BOTTEN 4 Pack 1" T-Bolt Hose Clamp, Clamp Range 32-37mm for 1" Hose ID, hose clamps Stainless Steel,hose clamp heavy duty,radiator hose clamps

I use these on 1" high pressure black HDPE 'Poly' pipe. The T-Bolt style are so much better than typical automotive hose clamps (aka: 'worm-drive' clamps). Since I started using T-Bolt clamps on my irrigation lines I seldom get a leak. And since all my pipe is buried, and will be for 30 years, any leak now or in the future is gonna ruin my day. I found the Botten 32 - 37mm to fit my 1inch SDR-11 (150psi) HDPE and PEX pipe perfectly. If you have SDR-9 (which is 250psi) pipe, the thicker walls on the pipe will require the next larger size of clamp. Just say'n.

Great Pool clamps. no leaks

Does the job
