1003 high pressure Union

The 1003 High-Pressure Union is designed for high-pressure pipeline connections where angular flexibility is required. Featuring a spherical seat design, this union allows up to 7.5 degrees of angular deflection in each direction, providing a total deflection capacity of 15 degrees. This flexibility helps accommodate angular misalignment during pipeline connection and installation.

The union combines steel-to-steel sealing surfaces with an NBR O-ring seal to help maintain connection airtightness at different angular positions. It is recommended for high-pressure pipeline connections where precise alignment is difficult and can be used with air, water, oil, mud, or gas, subject to application compatibility.

The 1003 High-Pressure Union has a standard 10,000 PSI NSCWP (Non-Shock Cold Working Pressure) rating. For 4-inch and 5-inch sizes, the specified NSCWP rating is 7,500 PSI. The union features a black nut and green components for product identification.
