OPW Hiltap 3U Series - Medium Pressure and Temperate Quality Unions

3U SERIES - Medium Pressure and Temperate Quality Unions

The 3U Series is an all purpose light weight quality union designed for leak proof operation as it cycles through a wide range of temperatures. The design offers a non-restrictive flow with no variation in pipe diameter in most sizes. The reusable metal-to-metal sealing components further enhance the seal as temperature and pressure changes are encountered. The safety ring ensures safe venting of residual pressure.

Applications

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.
