Uses:
- 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 (232°C).

Information:
- Torque values are based on dry bolts, the use of lubricant on bolts will adversely effect clamp performance.
- Worn-out hose couplings can be dangerous. They should be checked regularly and replace when necessary.
