Dresser Couplings Catalog
Built to endure the most demanding environments, Dresser couplings provide a versatile, bolt-tightened solution for joining pipes across water, gas, and industrial sectors. These mechanical powerhouses excel at absorbing vibration and accommodating thermal expansion, ensuring a resilient connection that moves with your infrastructure. Whether you are bridging dissimilar materials like steel and cast iron or securing high-pressure steam lines, the robust design of the Style 38 and Style 65 series delivers a leak-proof seal without the need for specialized tools. Engineers rely on the fusion-bonded epoxy coatings and high-strength alloy bolts to fight corrosion, while the flexible gasket technology handles everything from minor deflections to significant lateral offsets. From compact 1/2″ compression fittings to massive 400″ OD industrial sleeves, Dresser remains the gold standard for pipe joining performance and long-term reliability.
Top Dresser Couplings
Dresser Style 38 Bolted Coupling
The Style 38 is the industry’s most versatile and widely used bolted coupling, providing a flexible, leak-proof connection that accommodates expansion and vibration across a massive range of pipe sizes.
Dresser Style 65 Compression Coupling
This boltless, factory-assembled fitting is the go-to choice for quick installations on smaller diameter pipes, allowing you to create a secure joint in under a minute using only a wrench.
Dresser Style 90 Universal Coupling
The Style 90 offers a heavy-duty “universal” solution that provides both a high-pressure seal and positive pipe restraint, making it ideal for joining steel to polyethylene pipe in critical gas and water services.
Dresser Couplings sets the industry standard for high-performance pipeline integrity with American-made engineering that ensures every connection is as flexible as it is secure.

Bolted Couplings
The Style 38 and Style 39 series offer unmatched versatility for joining plain-end pipes while providing the necessary flexibility to absorb ground movement and vibration.
Compression Couplings
Heavy-duty Style 65 couplings allow for lightning-fast installation on smaller diameter lines, utilizing a thread-less compression design that eliminates the need for pipe threading or welding.
Wide Range and Large Diameter Couplings
These specialized connectors are engineered to bridge significant gaps in pipe outside diameters, making them the go-to choice for transitioning between different pipe materials in municipal water systems.
Leak Encapsulation Products
Designed for rapid response, these repair clamps and sleeves provide a permanent, pressure-rated seal over leaking joints without requiring a total system shutdown.
Tapping and Line Stopping Sleeves
Our tapping solutions allow for the safe addition of new branches or the isolation of pipe segments while the line remains under full operating pressure.
Expansion Joints
Engineered for high-stress environments, these joints protect your pipeline from structural damage by absorbing significant axial thermal expansion and contraction.
User Experiences
Mark Henderson I’ve been managing municipal water projects for over fifteen years, and we recently used the Dresser Style 38 bolted couplings for a major cast iron to ductile iron transition. The installation was incredibly straightforward despite the muddy trench conditions, and the ability of the coupling to handle minor deflection without leaking saved us hours of realignment work. It is rare to find a product that lives up to its pressure ratings so consistently, especially when dealing with older, irregular pipe surfaces.
Sarah Jenkins As a lead maintenance engineer for an industrial gas facility, I swear by the Style 65 compression couplings for our smaller utility lines. We had an emergency repair last month where welding wasn’t an option due to safety protocols, and the Style 65 allowed us to restore service in under twenty minutes with just a couple of wrenches. The galvanized finish has held up beautifully against the salt spray in our coastal location, proving that these are built for more than just standard indoor use.
Robert Miller We integrated Dresser’s expansion joints into our steam system overhaul last spring, and the performance has been flawless. The high-strength bolts and resilient gaskets have managed the constant thermal cycling of our plant without a single drop of seepage or loss of pressure. Knowing these parts are manufactured in Bradford, PA, gives me a lot of confidence in the quality control and the metallurgy of the steel sleeves we are putting into the ground.
Dresser FAQ
Can Dresser couplings be used to join pipes made of different materials?
Yes, Dresser couplings are specifically designed to join dissimilar pipe materials, such as connecting steel to cast iron or ductile iron, as long as the outside diameters fall within the coupling’s specified range.
Do I need special tools or welding to install a Style 65 coupling?
No, the Style 65 compression coupling is a threadless “handy” fitting that requires no welding, threading, or special equipment; it can be installed quickly using standard wrenches.
What is the maximum temperature rating for a Style 90 fitting?
The Style 90 seal-only fittings are generally rated for a maximum operating temperature of 212°F, making them suitable for most standard water and gas applications.
Where are Dresser products manufactured?
Dresser pipeline joining and repair products are proudly manufactured in the United States, with primary production facilities located in Bradford, Pennsylvania, and Olean, New York.
How much pipe deflection can a standard Style 38 coupling handle?
The amount of allowable deflection varies by size, but larger OD couplings typically support a deflection angle of approximately 2°, which helps the pipeline adapt to shifting soil or minor misalignments.
