Style 90 | Compression Fittings

Product Description

Product Features:

Dresser Coupling Style 90 have been installed on millions of natural gas service lines where they have helped to speed installation and cut costs.

Dresser Coupling Style 90 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 Dresser Coupling Style 90 are shipped assembled and ready-to-use.

Material:

Gasket Retainer Cup

  • Cup-shaped design of style 90 protects gasket.
  • Prevents friction between the gasket and end nut, resulting in consistent high performance.
  • Eliminates gasket interference in end nut threads, providing an accurate sense of tightness.
  • Closely confines the gasket, permitting more clearance between the end nut and pipe, and greater pipe deflection

 Gasket

  • An ample, wedge-shaped section gives reserve packing power and high gasket pressure in style 90 Dresser coupling.
  • Scientifically compounded rubber is made to last the life of the pipe.
  • Interchangeable with most of the corresponding sizes of gaskets used in Style 38 bolted Dresser couplings.

 Body

  • Machined, wedge-shaped flare provides a perfect gasket seat and uniform pack at all points.
  • Thickness always at least equal to that of pipe (on couplings, ells & tees).
  • Longitudinal pipe movement up to 1/16” per gasket may be safely absorbed.
  • Dresser Coupling Style 90 is made of rugged iron or steel.

 End Nut

  • High-grade iron, perfectly formed and rigidly inspected.
  • Long threading affords reserve “take-up” on gasket when needed and prevents stripping.
  • Clearance between pipe and nut permits more deflection of pipe (Possible because the gasket retainer cup also confines gasket).
  • Robust thread design resists stripping. (Test torques of 600 ft. lbs. reveal no stripping.)
  • Coarse, rugged threads make for easy starting.

 Dresser Coupling Style 90 offers 150 psig pressure rating as standard. Other pressures available upon request.
