The FIG 207 hammer union is designed for reliable sealing in oilfield and industrial connection systems. An O-shaped nitrile-butadiene rubber sealing ring is mounted on the shutoff head to help provide effective sealing performance. The threaded connector is interchangeable with FIG 200 and FIG 206 hammer union components, supporting practical compatibility in field operations.
FIG 207 hammer unions are commonly selected for applications where secure connection, maintainability, and dimensional compatibility are important. Butt weld Sch. 40 can be supplied for the applicable configuration. Detailed dimensions, materials, and weight data are listed below to support engineering selection and purchasing evaluation.
