4-bolt type with 4 gripping fingers and 2 clamp sections Bolts in Boss Clamps are designed to bend as they are tightened. This allows the clamp to conform to the hose outside diameter. Always tighten bolts to their specified torque value Periodic re-tightening of bolts is required due to “cold flow” phenomenon present in all rubber hoses Boss Clamps are for single use only! Once removed they are to be discarded. Recommended for steam service up to 450°F
