4-bolt type clamp with 2 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 deg 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
When installing stainless steel bolts and nuts, the use of anti-seize or anti-galling lubricant is advised, a light coat is required on the bolts to prevent thread galling and artificial torque reading
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
Recommended torque rating in ft. lbs
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
Always follow the manufacturer's product recommendations for pressurized steam handling
