The cutting and threading process can make the ends of steel pipe sharp, which can create an abrasive surface that leads to premature seal failure. To address this problem, FasTest (Minneapolis, MN) created the TwistMate MET-PT Series connector, featuring a unique seal design that is said to ensure a leak-tight seal every time. The connector provides a durable sealing surface, and by twisting the unit by hand, the patented design creates a leak-tight seal up to 750 psi as pressure is applied. —KD
