Vacuum Pipe and Fittings for Central Vacuums

SHIPPED REGULAR GROUND ONLY.

Industry standard central vacuum pipe for seamless connections into central vacuum elbows/connection/fittings. Central vacuum pipe is thin, only 1/16" thick with a 2" outer diameter whereas SCH-40 (schedule 40) PVC pipe is measured by inner diameter and is thicker (3/16").
Made from virgin PVC. Manufactured to ASTM-F 2158 standards and has no schedule rating or pressure rating since it is not irrigation related. If you need a complete lift of pipe (800ft total) enter 10 as the quantity and it will ship out via truck.

Ten pipes, four feet long. Central vacuum installation pipe is used for seamless connections with central vacuum fittings. Unlike Schedule 40 PVC tube, this is thin walled and has a 2" outer diameter whereas SCH-40 plumbing pipe is thicker and measured by inner diameter. Use for installation, repairs, relocating a valve, adding a valve, exhausting, etc. Be sure to get extra PVC couplings (below) to fit it all together. This vacuum tubing is 2-inch outer diameter. Manufactured to ASTM standard F2158.

Great for small central vacuum jobs such as repairs, relocating a valve, adding a valve, exhausting, etc. Be sure to get extra PVC couplings (below) to fit it all together. This vacuum tubing is 2-inch outer diameter. Manufactured to ASTM standard F2158.

Comes in two 2-foot sections. If putting two pieces together use a coupling (not included). Manufactured to ASTM standard F2158.

Used to hang 2" OD Central Vacuum Pipe at a distance of a foot or less. Comes with a nail. Make of sturdy PVC. The pipe snaps into the J and looks real clean. To order a case type in 25.

Use this fitting at the mounting plates only. Since this is the sharpest turn in the system, potential clogging will occur with easy access - right at the inlet valve! If you need a case, enter 90 for the quantity.

M.D. Manufacturing sells the highest quality fittings. We suggest avoiding PVC sch40 fittings. They are thin and leave a 'step' where the pipe connects. Toothpicks or pins can get stuck creating clogs. Also make sure fittings have a 3/4" cuff, not 1/2", to provide strength at joints. If you need a case, enter 115 for the quantity.

Spigot fittings are made to fit directly into other fittings. This will prove helpful in tight spots! If you need a case of these enter 115.

We suggest using 45's, even two of them when possible, to use less 90's. When the pipe line needs to run up or down, angle a 90 at 45-degrees into a 45 fitting. If you need a case, enter 125 for the quantity.

Spigots fit directly into another fitting. If you need a case, enter 125 for the quantity.

For connecting two pieces of pipe together. If you need a case, enter 200 for the quantity.

For connecting a branch to the main line. Be sure the airflow is adequate. Do not install the tee backwards! If you need a case, enter 45 for the quantity.

Includes the items pictured and comes in a handy box straight off our warehouse shelf. Add pipe (80ft recommended) and maybe some extra couplings. Buy regular PVC cement from a local store. Includes three pure white inlet valves and backing plates. The included wire is low voltage and runs from the faceplate to the vacuum canister to turn it on. In addition, Romex (110 volt) wire from a local store is need for the 110 volts. The faceplates' 110 volt wires connect to the romex you stub out from the backing plate box during rough-in. Made by Hayden.

Includes the items pictured and comes in a handy box straight off our warehouse shelf. Add pipe (40ft recommended) and maybe some extra couplings. Buy regular PVC cement from a local store. Includes one pure white inlet valve and backing plate. The included wire is low voltage and runs from the backing plate to the vacuum canister to turn it on. The wire does NOT have 110 volts. Made by Hayden.

Inner diameter is 2 inches and seamlessly mates with central vacuum pipe. High quality virgin PVC. If you need a case, enter 65 for the quantity.

The Straight Tee is not recommended for any part of a central vacuum installation. Use only when necessary. It has poor air-flow characteristics and when used for back to back inlet valves dirt is deposited behind the opposite inlet valve door.

Used mainly in existing home installations where the pipe is visible (in closets, for example). If you need a case, enter 500 for the quantity.

Most popular bracket for all rectangle shaped Basic Inlet Valve Covers. Install into new construction by nailing or screwing it into a stud. For existing home installation cut the plastic stud mounting side off and set it in a 2-3/8" x 4-1/4" hole cut into drywall (or wall material). Fasten inlet cover (with attached low voltage wire) to backing plate for a long lasting, firm hold. When piping, connect a fitting such as a tight 90 or coupling to the flange on the back side of the mounting bracket. For existing installation it is helpful to glue the fitting on before mounting it with the vacuum plate to the wall. If you need a case of these enter 75.

Includes attached coupling, gasket and screws. Used in new construction. Fix to a stud. When piping, connect a fitting such as a tight 90 or coupling to the back side flange. Finish it with a basic inlet valve cover.

For use in metal piping jobs use this part and its gasket along with #524S Flanged 90 Ell.
Case is 120.

A cosmetic inlet facing, used in existing home installations where the pipe and low voltage wire go into the drywall. If you need a case, enter 100 for the quantity.

Installed on the outside of the home to exhaust the power unit. This is not needed with M.D.'s bag type units. Fits 2" OD (Vacuum PVC Pipe). Overall size is 3-5/8"w X 4-5/8"h. Distance on the door flap is 2 3/4 inch. If you need a case, enter 40 for the quantity.

Useful in new construction installations to cover up the backing plate, protecting it from dry-walling and painting. Also lets drywallers know where to cut an opening. You can use a rectangle piece of cardboard to protect the hole and wires or one of these. NOTE: You'll need longer screws if your back mount is plastic and also note that this guard covers 90% of the back mount - the edges are open because the guard is rounded not square. If you need a case, enter 125 for the quantity.

For new construction when the pipe line penetrates the fire barrier wall in garages, for example. Use rubber cement and couplings to connect to standard vacuum PVC piping.

Fire Stop Ring by STI was designed specifically for the central vacuum industry. It is easy to apply and very affordable.

Flex Pipe is excellent for installing VacPan automatic dustpans. Central Vacuum 2" OD PVC pipe fits snugly into this flexible pipe that is 2" ID. Use a Hose Clamp for Flex Pipe for best connection, do not glue. Not recommended as a replacement for rigid pipe.
SOLD BY THE FOOT. Enter number of feet you need.

The Hose Clamp for Flex Pipe keeps your flexible pipe clamped down on the 2" OD central vacuum pipe good and tight. Please do not glue the flex pipe to the PVC but use a clamp of some sort such as this for best results.

This part is used for two things.

1. Hide-A-Hose inline hose stop. One side fits the pipe and the other side goes into a coupling which then takes the pipe. The stop should be installed several feet from the expected end of the hose.

2. Pipe adapter for 1.8125 inch OD pipe to 2 inch OD vac pipe. This adapter is used to mate smaller HP Vacuflo or any 1.8125 inch (1-13/16") outer diameter vacuum pipe (not SCH 40) to standard 2 inch OD thin wall central vacuum pipe.

Adapter used to mate smaller vacuum pipe (not SCH 40) with 1.75 inch Outer Diameter (as some Kenmore systems have) to standard 2 inch OD thin wall vacuum pipe.

Adapter connects 2" ID SCH40 PVC to Central Vacuum PVC 2" OD. It is never recommended that SCH40 is used in a central vacuum system. It is not created for the smooth travel of air and debris but rather water. Clogs are bound to happen. But if the system is nearly roughed in and the wall mounts will not connect to SCH40 use one of these adapters per inlet. Come off the mount with a central vac fitting, some pipe and then this adapter into the SCH40 pipe. Outer diameter of Schedule 40 is 2-3/16". Adapter inner diameter on one side is 2" and the other side 2-3/16".

Used to terminate the end of a vacuum pipe. Also used to cap the unused debris intake neck on any of MD's power units. If you need a case of these enter 50.

Is your power unit too loud? Decrease that irritating sound by inserting this muffler into any central vacuum that has 2" OD diameter exhaust port(s). One muffler per exhaust port on the vacuum itself. Use a 90 Spigot Sweep Ell (part #503 in Hardware / Pipe and Fittings) to install it vertically if desired. Total Length is 13.5 inches.

Use with 511SN when you have walls that are not as wide as standard 2x4 walls. If you need a case of these, please enter 75.

Use only with 511MP.

Tank Only, No Motor, Pre-Unit-Filter Tank. Dirty air goes into the non-centered intake on top of the tank. As it enters the tank it creates a cyclonic cleaning action causing 96% of the debris to fall down to the bottom. The air is then moved out of the tank through the center hole on top where it heads to the actual motorized vacuum unit. Size: 31" tall, 14" wide, and holds 7 gallons.

Can be used in either direction. Wide side: inner diameter is 2", outer is 2-1/4". Narrow side: inner diameter is 1-7/8" and outer is 2-1/8". Central vacuum pipe fits into it to extent the exhaust. Central vacuum tubing is thin wall PVC, not SCH40. But SCH40 can be used, the 1.5" ID has a 2" OD that fits into the coupling like vacuum pipe does. SCH40 is three times thicker so the exhaust might be constricted a little, but with no adverse affects.

The Air Relief Valve stops damage to your motor caused by clogs and blockage. In the instance that a clog or blockage occurs the valve will spring open, allowing air to the motor, which prevents damage to the motor. You will need to purchase a sweep tee connector and splice it into your pipes - the closer to the unit the better.

The parts and and adapters you need to swap out your old central vacuum power unit for a new one from M.D. Manufacturing, Inc. Comes with two 2-foot sections of central vacuum pipe. Includes an adapter for narrower Kenmore PVC pipe. Kit has a hose adapter to fit a new hose into a 1-1/4 inch diameter vacuum wall port so you can buy any new attachment kit and be assured it fits any central vacuum system no matter the brand, year or model.
