How the TECH-O-SEAL System Works
Two flat faced components–a threadpiece and a tailpiece–are joined by a union nut. The threadpiece is manufactured with a recessed groove that accommodates an elastic O-Ring–the secret behind this highly effective system. An initial leak proof seal is made by hand tightening the nut. Subsequent pressures in the line, by forcing the O-Ring to the outer edge of the groove, actually further strengthens the seal.
