Question by: Terry S on Sep 15, 2025, 4:06 PM

What size hose does this clamp fit best? I'm lookin' at a 2 1/2 inch ID hose.

Answer by: Customer Support on Sep 16, 2025, 4:11 PM

This constant torque clamp works with hoses having an inner diameter from 2-3/8 inches to 3 inches. So, a 2 1/2 inch ID hose should be a good fit.

Question by: Pete R on Jul 6, 2025, 1:09 PM

does this clamp actually hold steady when temps swing a lot, like real hot then cold? worried about it loosening up over time on a silicone hose

Answer by: Customer Support on Jul 8, 2025, 8:02 AM

That's exactly what the constant torque design handles. The Belleville spring washers built into the clamp maintain continuous pressure as the hose material expands and contracts with temperature changes. So instead of going slack when things cool down or over-compressing when they heat up, the clamp adjusts and holds consistent clamping force throughout. The internal liner also protects silicone hose from getting cut into or extruded under that pressure, which is a real concern with softer hose materials.
