Product Questions & Answers

What kind of clamps do I need to use with this hose? Don't wanna mess it up.

Question by: Kurt A on Aug 15, 2025, 3:44 PM

For fitting attachments, Oetiker Stepless Ear Pinch Clamps and Trident #730 S.S. Constant-Torque Clamps are recommended. You shouldn't use serrated, slotted, or wire-type clamps, though.

what's the temp range on this hose? running it on an engine brake system and need to know if it'll hold up to the heat

Question by: Shane W on Feb 17, 2026, 5:44 PM

Rated for continuous use from -65°F up to 350°F, so it handles the kind of heat engine brake systems throw at it without breaking down. The nylon fiber reinforcement adds to that durability, and the silicone construction holds up against coolant additives too. For that application, it's a solid fit.
