OPW Hiltap 3IU Series High Performance Quality Impact Unions

3IU SERIES High Performance Quality Impact Unions

The Hiltap™ 3IU impact union does what a conventional hammer union does, only better. Our "impact union" is designed for leak proof operation over a wide range of temperatures and pressures. The reuseable sealing components offer a metal-to-metal wedge seal, as well as an additional o-ring seal, targeting full compliance to the latest environmental laws.

Applications include: Next to sensitive electronic equipment e.g. most flow meters, modular skid "tie-ins", high pressure gas/oil, meter/production flow production, gas distribution "tie-ins", high axial load stresses, sour gas, unconventionally high pressures and high erosion/corrosion applications.
