Dresser Couplings

Overview

Products feature Dresser AL-CLAD™ coating as standard in the most popular sizes. Our epoxy coating offers optimum protection against highly corrosive soil or aggressive water conditions and for handling brine, brackish water, most acids, alkalies, oil, chemical particulates and gases.
Use a Dresser coupling and your pipeline joint is non-rigid, accepting expansion, contraction, vibration and line deflection.

Dresser Style 38 Coupling

Proven by years of service on all kinds of pipe, Dresser Style 38 couplings provide flexible, leak proof connections that last the life of the pipe. No costly threading, beveling, exact pipe fitting or alignment is required. Dresser couplings are fast and easy to install with any size pipe or tubing. The resilient Dresser gaskets absorb harsh vibration and pipe movement, while still allowing curves to be laid with straight pipe lengths. Installation is safe and sure; there are no hazards to workmen or delays due to weather. Dresser Style 38 Couplings are available from 1/2" ID to over 400" OD.

Dresser Style 40 Coupling

Dresser Style 40 Long Couplings provide a simple and effective method of joining pipe when gaps in pipe ends are wider than ordinary. Style 40 couplings are similar in construction to Style 38 couplings except that middle rings are longer and have a larger belly diameter. Though longer, they absorb the same amount of expansion and contraction as the Style 38 coupling up to 3/8" per joint. 

Dresser Style 167 Lock Coupling

Dresser Style 167 Lock Couplings actually "lock" the pipe and the coupling together to protect the line from pipe separation due to unusual movement. These couplings are for exceptional conditions such as ash handling and coal transmission lines, or unanchored high-pressure surface lines where added holding strength is desired.

Style 167 lock couplings utilize standard Style 38 parts with the addition of leak-proof locking pins. The locking arrangement consists of threaded steel locking plugs at each end which extend through the middle ring into corresponding holes drilled in the pipe ends. This construction permits a "universal joint" action of the pipe in the coupling, yet prevents the pipe from pulling out under excessive longitudinal stresses.
