  • 5/16” (7.9mm) slotted hex head screw made of 410 stainless steel
  • Meets SAE standard J1508 Type “F”

Constant Torque Hose Clamps

More Info
Call us at 1-800-944-5463 to order!

 

A revolutionary clamp that reacts to changes in hose systems by actually increasing or decreasing its own diameter as the system expands or contracts. Used for leakage or rupture problems because of “cold flow” or changes in environmental or operational temperatures. Aero-Seal construction for use on small diameter applications-torque rated 30-70 in./lbs. Heavy-duty construction for use on large diameter applications-torque rated 50-125 in./lbs.
