Product Overview – HD T-Bolt Spring Load Clamp 3.81 in to 4.13 in

HD T-Bolt Spring Load Clamp 3.81 in to 4.13 in (OTX-4ST381H) is a reliable heavy-duty spring-loaded T-bolt clamp for charge air cooler, turbo and intake hoses, with a clamping range of 3-13/16 in to 4-1/8 in (97–105 mm).

A built-in spring keeps tension on the hose as it expands and contracts with heat and pressure, so the joint stays sealed without re-tightening.

Construction: a 301 stainless steel band 3/4 in wide, a zinc plated carbon steel screw, a 1/2 in nut, with a torque rating of 150 in-lbs.
