Style 38 Couplings

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. Installation 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 furnished for practically any size or special condition.
