## Features

- 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
- Recommended for steam service up to 450°F
- The bolts used in the boss interlocking clamps are not standard bolts
- They vary from standard bolts in their length, diameter, overall thread length and material hardness
- These bolts can be retorqued, but it is not recommended that the bolts or clamps be reused, as they are designed for a single bend only
- Torque values for clamps 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
- Each coupling user should review applications and add safety devices where indicated
- Note: pressurized steam is an extremely dangerous commodity
- Only hose, fittings, clamps and accessory items that have been approved for steam service should ever be used! never use an unapproved item for steam service
