Product Overview \u2013 HD T-Bolt Spring Load Clamp 3.06 in to 3.38 in<\/h3>\n

When a standard clamp is not enough, the OTX-4ST306H heavy-duty spring-loaded T-bolt clamp (3-1\/16 in to 3-3\/8 in (78\u201386 mm)) gives a dependable seal on charge air cooler, turbo and intake hoses.<\/p>\n

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.<\/p>\n

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.<\/p>\n

It interchanges with 4 aftermarket part numbers from brands such as Breeze, Excoh, Norma, including Excoh 4ST306H, Norma 3630004082, Norma 0363 0004 082.<\/p>\n
