HAMMER SEAL UNIONS

PRV INDUSTRIES offers 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″.
