Description & Features

Introducing the TRIDENT RUBBER LLC Constant Torque Clamp featuring an internal liner that shields soft or silicone hoses from damage. The clamp adjusts as needed with a 5/8 inch wide 304 stainless steel band and housing. Its 410 stainless steel Belleville spring washers and screw ensure durability.

Compensates for "cold flow" and expansion or contraction in extreme temperatures.

Visual "Torque Check" feature simplifies inspection and adjustment.

Extended adjustment range of 7/8 inch O.D. suitable for sealed systems and hard-to-reach areas.

Installation is straightforward; tighten until the screw tip extends 1/4 inch beyond the housing and the washers nearly collapse flat. A torque wrench set to 90-125 inch pounds is recommended.
