Dresser Style 90 Compression Coupling

These couplings are often called Dresser Style 90 Gas Service Coupling since they are commonly used on gas lines. Over the years, millions of Dresser Style 90 Fittings have been installed on natural gas service lines where they have helped to speed installation and cut costs. Style 90 couplings and fittings consist of a cast iron or forged steel body; two resilient, specially compounded gaskets; two steel, self-centering protective gasket retainer cups, and two heavy end nuts. All fittings are shipped assembled and ready-to-use.

Style 90 Insulating Couplings with Full-sleeve Insulators

With the Style 90 insulating coupling, a full length body insulator, together with the insulating gasket, effectively isolates the insulating end of the coupling from the pipe. The body insulator also facilitates installation of the coupling and aids correct reassembly if the coupling is disassembled. A high resistance, gas-tight insulating joint is provided, even with pipe-end deflection of up to 3 degrees.

Also, the sliding pipe-end spacer assures proper separation of pipe ends within the coupling for effective insulation. The full-sleeve insulator working in combination with the pipe-end spacer makes proper installation of the Style 90 insulating coupling virtually foolproof.

Dresser Style 65 Compression Coupling

Dresser Style 65 couplings are available in regular and long couplings, 90° Ell, and male and female adapters. Style 65 bodies are made of either steel or malleable iron; fitting bodies constructed of malleable iron conform to ANSI specifications for 150 psi rated fittings. The gasket retainer ring is made of cold-rolled carbon steel.

Shipped completely assembled and ready to use, Dresser Style 65 compression fittings install quickly onto plain-end pipe or tubing. Simply loosen the end nuts, stab the pipe into the fittings and tighten end nuts with a wrench. The connection is complete in less than a minute! No threading, flaring or exact pipe fitting required. Plus, the pipe joint can be easily disassembled for cleaning or repairs.

Style 65 compression fittings employ the same time-proven sealing principle that was developed by Dresser in 1891. The resilient gasket sealing principle provides permanent flexibility while absorbing expansion, contraction, vibration, stresses and deflection movement. Threaded pipes rob a pipe end of   40% of its strength. With Dresser Style 65 compression fittings you can use plain-end pipe and maintain uniform wall thickness throughout every joint in your piping system. Dresser Grade 27 Armored gaskets are supplied as standard, with Grade 42 Armored oil resistant gaskets available for special applications on request.

NOTE: Regular Style 65 couplings and fittings should not be used for temperatures over 150° F.
