Description
The Dresser Style 65 is a complete family of boltless compression couplings and fittings engineered for plain-end steel pipe connections. Using the same time-proven sealing principle Dresser developed in 1891, Style 65 fittings ship fully assembled and ready to use — install them in under a minute with nothing more than a wrench. No threading, flaring, or exact pipe-end preparation required. The connection is also fully demountable for cleaning, inspection, or system modifications.
Style 65 bodies are available in steel and malleable iron; malleable iron fitting bodies conform to ANSI specifications for 150 PSI rated fittings. The gasket retainer ring is made of cold-rolled carbon steel. Dresser Grade 27 Armored® gaskets are standard; Grade 42 Armored oil-resistant gaskets are available for special applications on request. Temperature limit is 150°F for regular couplings — for temperatures 150°F to 350°F, the Style 165 Plus-Temp™ is recommended.
The complete Style 65 line includes regular couplings, long couplings, 90° ells, female adapters, and male adapters, all in sizes 1/2" through 2". Insulating Adapter Gaskets are available for use with Style 65 couplings when connecting dissimilar metals (e.g., steel pipe to copper tubing) to prevent galvanic corrosion.
Key Features
- Installation complete in under a minute — no threading, flaring, or exact pipe fitting required
- Ships fully assembled; no loose parts or special tools needed
- Demountable joint — easily disassembled for cleaning or system changes
- Maintains uniform pipe wall thickness; no thread-cutting that removes 40% of pipe strength
- Flexible joint absorbs expansion, contraction, vibration, stress, and deflection movement
- Grade 27 Armored® gaskets standard; Grade 42 oil-resistant available on request
- Insulating Adapter Gaskets available for dissimilar metal connections
- Available in e-coat and galvanized finishes; sizes 1/2" through 2"
How It Works
Threaded end nuts (1) screw onto the threaded body (2), compressing resilient gaskets (3) against the pipe (4) to form a flexible, bottle-tight seal. Gasket retainer rings (5) confine and protect each gasket from damage and prevent friction between the gasket and end nut, providing an accurate sense of tightness and consistent sealing performance on every installation. Simply loosen the end nuts, stab the pipe into the fitting, and tighten with a wrench — the connection is complete.

All dimensions are maximum, approximate, and given in inches. Dim. A = across corner of octagonal end nut; B = overall length; C = coupling body length; D = center-to-end (ells only). Standard finishes: E-coat and galvanized for regular and long couplings; galvanized only for 90° ells, female, and male adapters. Where pipe movement could occur, pipe must be properly anchored.
