Dresser couplings provide flexible, leak-proof connections that are designed to be low-maintenance and ensure product longevity.
Style 38
Available from 1/2″ up to 120″ diameter and larger, and be engineered to high pressure and large diameter application.
Style 138 Bolted Couplings for CIP/DIP
Now you can stock one coupling in each nominal size, 4” through 12”, and be sure of a fit! Whether the cast-iron pipe was made in 1890, or from your latest shipment.
Style 39
The Dresser Style 39 Insulating Coupling is widely used on gas service lines but they are especially ideal for water and industrial applications – water lines, tank hook-ups, intake and discharge lines, pumping stations – anywhere that electrical isolation is required.
Style 40 Long Body
Dresser Style 40 Long Body Couplings provide a simple and effective method of joining pipe when gaps in pipe ends are wider than usual. Style 40 couplings are similar in construction to Style 38 couplings except that middle rings are longer.
Style 62 Reducing/ Transition
When is using the Dresser Style 62 Reducing Coupling ideal?
- When making actual reductions in pipe size
- When changing the class of pipe
- When joining steel and cast-iron pipe
They can be supplied for connections between any two kinds or sizes of pipe.
Style 31 Line Caps
Dresser Style 31 Line Caps are used to close off sections of a pipeline during construction and testing, and to cap off dead-ends in the line for future branch connections.

Style 128 Flange Adapter
Fabricated from high-strength steel, Dresser Style 128 Flange Adapters are offered standard up to 24” diameter in steel and cast-iron pipe sizes.
The compression end of the adapter has a Dresser coupling-type design utilizing a wedge gasket for an efficient, leak-proof seal. Larger sizes are available upon request—talk to your DPS representative today!
Style 131 Dismantling Joints
The Dresser Style 131 Dismantling Joint is a double-ended flanged adapter that allows for longitudinal adjustment in piping systems where flanged end pipe is the standard.
The Style 131 will provide the maximum in flexibility when installing and maintaining flanged end pipe interfaces with check valves, gate valves, ball valves, pumps, blowers, meters, engines, compressors, various fittings and accessories.
Style 63 Expansion Joints
The Dresser Style 63 Expansion Joint are used when no flexible joints are used in the pipeline or when the amount of concentrated movement at one point is in excess of the amount that can safely be absorbed by standard couplings.
Provided with rugged welded steel construction, the Style 63 is available in stainless or carbon steel.

Style 167 Lock Couplings
When it comes to Dresser quality, there’s nothing unusual about the Style 167 Lock Coupling!
The Dresser 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.
