200 psi poly pipe repair


I recently cut through my 1" 200 psi poly pipe wich feeds to the back yard and is under pressure all thetime and I tried to find cinch clamps for it and unabel to use the regular 1" Cinch Clamp. What size cinch clamp do I need and can I use a standard inch coupler with barbs to repir this line.

200 PSI? that's an unusually high pressure for water---

200 psi poly pipe repair


some water pressures have reported over 112 psi for our waterdistict. the poly was put in insted of PVC pipe. A regular 1 inch cinch clamp will not fit over a 1 inch 200 psi poly because of the thickness of it.

Use a barbed insert and hose clamps- standard procedure on 200 psi pipe. May need a little torch heat to get the insert in

Do me a favor and find out at your convenience. Is it like a Ford or McDonald fitting only plastic?

I've used a brass compression repair coupling in high pressure situations with great success.
