The 1-1/8 in. Nominal 2-Ear Hose Clamp is a two-ear stainless steel ear (pinch) clamp that creates a permanent, 360° leak-free seal by mechanically deforming the raised ear(s) with a pinch clamp tool. Unlike worm-drive clamps, ear clamps cannot be loosened after crimping — the seal is permanent and vibration-proof. Two ears provide higher clamping force than single-ear designs — specified for thicker hose walls, higher pressure connections, or larger tube ODs.

- Stainless steel resists corrosion from coolant, fuel, and chemical exposure
- OEM standard for automotive cooling, heater hose, and under-hood connections
- Requires dedicated pinch clamp tool (sold separately) for correct crimping
- Compact profile — fits in tight spaces where worm-drive clamps would interfere
Common Applications
Automotive cooling system and heater hose connections, fuel system hose clamps, appliance water inlet connections, medical device fluid circuits, industrial hose assemblies, and any application requiring a permanent, vibration-proof hose seal that will not be serviced or removed.
