Hammer Union Nuts

What are Hammer Unions?

Hammer unions are commonly used in oilfield industry to seal two pieces of pipe or hose together and connected by threads or welds. They 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. To fit different sizes of pipe or hose, corresponding types of hammer unions are designed. In most cases, they come in sizes from 1" up to 10" and in pressures from 1,000 psi up to 15,000 psi. We distinguish pressure ratings with diffierent colours. Below is the chart for complete pressure rating and color codes for each high presure hammer union availible.
