Couplings and male/female adapters for copper tubing.
Dresser Style 88 fittings are handy, ready-to-use boltless connectors specially designed for use with copper tubing. Their use eliminates such operations as cutting and squaring of tubing ends, squaring, soldering and brazing. The Dresser sealing principle assures an absolutely tight joint. Insulating adapter gaskets are also available to adapt Style 90 and Style 65 couplings and fittings to copper tube sizes. Each Style 88 fitting consists of a brass, malleable or steel body, as usage dictates, two rugged malleable or brass end nuts, and two resilient ARMORED gaskets, protected against damage from threads by gasket retainer cups. Gaskets are made of our exclusive Dresser rubber compound, with helical coil armours. All castings are 100 percent air-tested to assure a leak-proof seal.
