Style 38 Couplings
Sizes and Specifications for Steel Pipe
Overall Dimensions
Proven by years of service on all kinds
of pipe, Dresser Style 38 couplings
provide flexible, leakproof connections
that last the life of the pipe. No costly
threading, beveling, exact pipe fitting
or alignment is required. The resilient
Dresser gaskets absorb vibration and
pipe movement and permit curves to be
laid with straight pipe lengths. Installa-
tion is safe and sure. There’s no hazard
to workmen or delays due to weather.
Dresser Style 38 couplings are available
from 1/2” ID to over 400” OD.
NOTE: Commonly used sizes are listed
in the tables, but couplings can be fur-
nished for practically any size or special
condition. Penstock coupling brochure
available on-line: www.dresser.com.
