O-SEAL (Pipe) & MARK VIII (Tubing) Fittings
CPV O-SEAL System flat-faced tube & pipe fittings for unlimited break-remake leakproof flexibility. The O-SEAL System of separable tube and pipe fittings offers a variety of end connection configurations to allow versatile pipe & tubing design flexibility. The union nut found in all O-SEAL System union connections is used to join two mating fittings…a tailpiece and a threaded piece or valve body. In this way variety of end connections types and styles may be specified. Brazed/Welded or threaded connections are available in pipe and/or tube sizes in any combination. In all cases the O-SEAL System provides leakproof reliability from vacuum to 6000 psi with unlimited break-remake flexibility.
At the heart of each union end connection is the CPV O-SEAL O-ring. Sealing is accomplished by the O-ring, which is recessed in a close-tolerance grove in one of the two mating metal pieces. When tightened, the union nut compresses the O-ring to provide an initial seal between the static metal surfaces. As the line pressure increases, the O-ring is pressed against the outer wall of the groove, effectively sealing even minute surface voids and assuring a leakproof connection.
O-SEAL end connections can be specified in nearly 40 different types and styles including elbows, tees and crosses and in pipe and tube sizes from 1/8” to 2”.
