"Slip in, Slip out" convenience

The unique CPV O-SEAL System design employs a flexible O-ring that is recessed into a close tolerance groove on each of the flat-faced union ends for slip in, slip out convenience. This creates a bubble tight seal that can withstand heavy vibration or pressure surges far better than gasket or metal-to-metal type seals. 

O-SEAL System Valves also provide users a cost-of-maintenance advantage by having a completely interchangeable valve cartridge.  The soft goods in the cartridge is removable and can be specified in different materials for special applications.  The software group is determined by compatability with the liquid or gas and the temperature range of the application. Because the cartridge is easily removed from the valve for maintenance or replacement, the cost of purchasing a new valve can be avoided.  In most cases, the old cartridge can be serviced off-line with a new soft goods kit and other soft goods for reuse another time when need arises.

CPV O-SEAL System flat-faced tube and pipe fittings
for unlimited break-remake leakproof flexibility
Catalog 68

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”.
