HAMMER SEAL UNION

Recommended for Mud tanks, mud tank connecting lines, and pump suction flanges

Nitrile seal provides a compression seal. Elongated cross-section of seal ring ensures greater sealing surface when in contact with the pipe. Accepts up to 7º pipe misalignment. 6, 8, and 10-inch sizes require butt-weld.
