The connector is designed specifically to connect and seal threaded pipe. The ends of steel pipe are often sharp from the cutting and threading process, and this abrasive surface can cause premature seal failure. Engineers have addressed this problem with this connector, featuring a unique seal design that provides a durable sealing surface to ensure a leak-tight seal. No wrenches or tape is needed to make leak-tight connections in pressure testing applications. The patented design provides a quick and user-friendly seal with a simple twist of the hand motion until surface contact is made.
