HAMMER SEAL UNIONS

As a trusted Hammer Seal Union manufacturer in India, PRV INDUSTRIES provides reliable solutions for connecting mud tanks with speed, strength, and leak-proof performance. Our mud tank unions are commonly known as hammer seal unions. Our Hammerseal Unions are designed to join drilling mud tanks quickly and without leaks. The external threaded male portion of the union welds to a pipe stub at the tank wall. A smaller O.D. connecting pipe extends through the female portion, the o-ring, and then the male portion of the union. When the internally threaded female component is tightened onto the male component, the o-ring between the components is squeezed to an oblong cross-section. The o-ring then seals against the O.D. of the connecting pipe. Hammerseal unions are offered in sizes 4″ through 14″.
