{"product_id":"aircomparts-flexible-compression-pipe-coupler-rotary-screw","title":"ACS Flexible Pipe Joint Coupler for Rotary Screw Air Piping, 1 in. to 4 in.","description":"\u003cp\u003eA 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.\u003c\/p\u003e\n\u003ch3\u003eSizes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 in. nominal pipe (P1419)\u003c\/li\u003e\n\u003cli\u003e1-1\/4 in. nominal pipe (P1420)\u003c\/li\u003e\n\u003cli\u003e1-1\/2 in. nominal pipe (P1425)\u003c\/li\u003e\n\u003cli\u003e2 in. nominal pipe (P1430)\u003c\/li\u003e\n\u003cli\u003e2-1\/2 in. nominal pipe (P1435)\u003c\/li\u003e\n\u003cli\u003e3 in. nominal pipe (P1440)\u003c\/li\u003e\n\u003cli\u003e4 in. nominal pipe (P1450)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHow to choose\u003c\/h3\u003e\n\u003cp\u003eOrder by nominal pipe size, the same size as the pipe you are joining.
