Couplers - HILTAP, High Temperature Fluid Transfer

For the Toughest High Low Temperature and Pressure Applications

OPW’s HILTAP™ series features innovative couplings for high and low pressures as well as temperatures. For over a decade, the HILTAP™ and RapidLOK family of products have served global industries, providing safe transfer solutions for some of the most difficult and demanding liquid applications.

This all-purpose, high-performance quick coupling offers a non-restrictive flow with no variation in pipe diameter when required and conditions allow.

The reusable sealing components are made of different metals that have their own unique hardness and thermal properties, so as to further enhance the seal as temperature changes are encountered.

The sleeve retaining ring ensures safe venting at any residual pressure. The HILTAP™ Brand offers front line solutions and allows design engineers to specify safe and environmentally responsible connections.
