ACS Flexible Pipe Joint Coupler for Rotary Screw Air Piping, 1 in. to 4 in.
A flexible compression pipe coupler joins two plain-end pipes without threading, welding or grooving them. The coupler body clamps over both pipe ends and a red silicone rubber donut inside does the sealing, which lets the joint absorb the vibration and thermal movement that a rotary screw package puts into its discharge piping. It is also the fastest way to break a line for service: loosen the coupler, pull the pipe, no pipe wrench and no torch.
Sizes
- 1 in. nominal pipe (P1419)
- 1-1/4 in. nominal pipe (P1420)
- 1-1/2 in. nominal pipe (P1425)
- 2 in. nominal pipe (P1430)
- 2-1/2 in. nominal pipe (P1435)
- 3 in. nominal pipe (P1440)
- 4 in. nominal pipe (P1450)
How to choose
Order by nominal pipe size, the same size as the pipe you are joining. AirComParts sizes this coupler family and its donut seals for schedule 40 standard steel pipe, so measure the pipe, not the fitting.
Matching donut seals
Each coupler seals on a red silicone rubber donut, sold separately. The donut is the wear part: when a joint starts weeping it is almost always the donut that has taken a heat set, not the coupler body. Pair them like this:
- 1 in. coupler to the 1.315 in. ID donut (P1302)
- 1-1/4 in. coupler to the 1.660 in. ID donut (P1303)
- 1-1/2 in. coupler to the 1.900 in. ID donut (P1304)
- 2 in. coupler to the 2.375 in. ID donut (P1305)
- 2-1/2 in. coupler to the 2.875 in. ID donut (P1306)
- 3 in. coupler to the 3.500 in. ID donut (P1307)
- 4 in. coupler to the 4.500 in. ID donut (P1309)
Typical applications
Rotary screw compressor discharge piping, separator tank and aftercooler connections, dryer and receiver tie-ins, and shop air headers that need a serviceable joint. Anywhere a rigid threaded joint would transmit package vibration into the pipe run or crack under thermal cycling.
AirComParts flexible compression pipe couplers join plain-end schedule 40 steel pipe on rotary screw air compressor installations, in 1 in., 1-1/4 in., 1-1/2 in., 2 in., 2-1/2 in., 3 in. and 4 in. sizes, sealing on replaceable red silicone donuts.
