The features of hammer union

● Reliable Sealing Performance : Seal rings are made of quality rubber compound which greatly enhance load-bearing capacity and sealing performance and protect connectors from erosion . Different pressures and applications have different sealing method .

● Fast Installation :   Wherever they are, wing nuts and rigid ACME will ensure quick installation or dismantling without special tools .

● Highly Interchangeable:   All unions are made in English system, and can be interchanged with products in international market. Seal rings are fully interchangeable with SPM or FMC equivalent products; Marks of size and pressure in wing nuts are formed in die-forging model, same as international products .

● Advanced Machining and Inspection Method : Spherical adapters machined by precision NC machine tools and LP thread machined by special cutting tools can ensure high sealing performance; Wing nuts machined by NC machines have high strength and load-bearing capacity; Welding materials and welding grooves conform to API 16C; Unions for sour gas environment are strictly manufactured to NACE- MR0175 and API RP- 14E .
