Stepless Ear Pinch Clamp, Stainless, 0.882 - 1.008 Inch Clamping Range, 0.276 Inch Width

Polyurethane is exactly the kind of tubing this clamp is built around. The smooth inner band keeps the hose surface from getting nicked or pinched during installation, and the tongue-in-groove design closes into a full 360-degree seal all the way around. For thin-walled or low durometer lines, that even clamping pressure matters a lot, and this one delivers it without biting into the material.
