When you need a coupling for highly corrosive conditions - too corrosive for ordinary carbon steel
couplings - Dresser offers its proven Style 38 coupling in an all-stainless steel design. The coupling
is available in either Type 304 or Type 316 stainless steel. Followers are available in Type 316 only.
You can also specify the middle ring only in stainless or the nuts and bolts only in stainless.
Dresser Style 38 stainless steel couplings are furnished with gaskets to match the particular
service. Available compounds include Buna S (Grade 27) and Buna N (Grade 42), fluorocarbon
(Viton
®
)*, butyl and EPDM. There’s also a high temperature gasket for applications up to 1200° F.
See gasket recommendation chart on inside back cover.
Dresser stainless steel couplings provide flexible, bottle-tight connections with no need for costly
threading, beveling, exact pipe fittings or alignment. Installation is so easy, ordinary workmen can
make tight joints every time, only tool needed is a wrench.

Please specify if pipe stop is required.
2- Bolts - Furnished E-Coated steel as standard.
3- Gasket - Information appears on Page 20.
* Light Pattern Couplings - Standard pressure rating of 150 psi.
For severe service
conditions!
Style 38 Stainless Couplings
4- Dimension “L” - Overall length taken with fasteners drawn up finger tight.
5- Working Pressure - Pressure ratings are determined on the basis of
Barlow’s formula using a working stress equal to one half the minimum yield
of the middle ring material.
