TBLS Spring-Loaded T-bolt clamp
Murray spring-loaded clamps are designed to compensate for the expansion and contraction of hose caused by temperature and/or hose cold flow. Typical installations include silicone hoses on charge air cooling/air-to-air, after cooling systems and primary engine coolant systems. TBLS series clamps are 300 Series Stainless Steel construction with plated carbon steel bolts, springs and selflocking nuts.
NOTE: Coil springs should not be compressed to solid at installation. Make sure the nut is positioned approximately one to two turns from solid. This allows the clamp to expand and contract.

Recommended Installation Torque: Plated Steel Bolt & Nut: 50-60in.lbs. (5.6 - 6.8Nm) 300 Series Stainless Bolt & Nut: 50-60in.lbs. (5.6 - 6.8Nm)
