Boss® clamps 4-bolt type with 4 gripping fingers and 2 clamp sections are designed to bend as they are tightened to conform to the hose outside diameter. Tighten bolts to their specified torque value. Clamps will need to have bolts re-tightened periodically due to pressure changes in rubber hoses. Boss® clamps are for single use only- once they are removed they need to be discarded. The 350 clamp for use with Boss® System stems and couplings.

Installation
- Torque values for clamps are based on dry bolts. The use of lubricant on bolts will adversely effect clamp performance. Do not lubricate nuts and bolts
- Torque values for clamps are based on dry bolts.
- Bolts in Boss® Clamps are designed to bend as they are tightened which allows clamp to conform to the hose outside diameter
