Hammer Unions 
 
 
               Hammer Unions are high-pressure threaded or welded connections with two halves a threaded female half and a wing male half with swivel nut that fit together and seal upon turning and then hammering the nut half together with the threaded half. Weco-style hammer unions come in sizes from 1" up to 10" and in pressures from 1,000 psi up to 15,000 psi. These type of hammer unions are commonly used in oilfield and industrial applications to seal two pieces of pipe or hose together by making a connection via threads or welds.

                We offer a full line of Hammer Unions and Hammer Seals connections to fit a variety of applications. Hammer unions come in N.P.T. threaded-style and welded-style and are made of heavy duty steel in sch 40 sch 80 & xxh for tough and long lasting use. 

               Hammer unions are color coded to specific pressure ratings for example a figure 1502 is red and blue nut and is rated for 15,000 psi where as a figure 100 is yellow with black nut and rated for 1,000 psi. Please see below chart for complete pressure rating and color codes for each high presure hammer union availible.

                                              HAMMER SEALS

 

 

             Hammerseal Unions are designed to quickly join mud tanks without the work associated with flanged connections. Even if the tanks are not aligned perfectly, Hammerseal Unions can still be made up tight for a non-leak seal. The externally threaded female portion of the union welds to a stub of pipe at the tank wall. Connecting pipe extends through the nut, the macro o-ring and then into the female. When the internally threaded nut is hammered tight onto the female, the captive o-ring is compressed into a "D" square cross section, sealing fluid pressures.
