Gallagher Fluid Seals Expands Machining Capabilities to Better Serve a Growing Market

At Gallagher Fluid Seals, we’ve built our reputation over the past 70 years by engineering high-performance sealing solutions that meet the evolving demands of today’s industrial markets. From servicing top-tier OEMs and MROs to supporting distributors across the U.S. and Europe, our mission has remained constant: deliver quality seals, on time, and at a competitive price.

Now, we’re taking that commitment even further.

Gallagher has significantly expanded its machining capabilities, investing in advanced equipment, growing our in-house design and engineering expertise, and positioning our team for a new phase of growth in the sealing industry. With an upgraded facility and enhanced tooling capacity, we’re ready to meet a broader range of customer needs, from high-volume production to highly customized sealing components.

Precision Machining for High-Performance Products

Our core manufacturing capabilities center around some of the most trusted and technically demanding sealing products on the market. These include:

PTFE Spring Energized Seals (SES) – Ideal for critical applications in extreme temperatures and pressures.
PTFE Metal Case Lip Seals (MCLS) – Designed for rotary applications where durability and low friction are essential.
Back-up Rings – Both solid and split designs, supporting extrusion resistance and seal longevity.
Elastomer and Urethane Seals – Commonly used in hydraulic and pneumatic applications, offering excellent resilience and sealing reliability.

Each product is manufactured with precision in our upgraded facilities, using both standard and custom-engineered materials - most notably our wide access to PTFE blends and in-house spring design capabilities. This allows us to build exactly to specification while maintaining flexibility across a variety of operating conditions and industries.

Advanced Equipment, Enhanced Capacity

Our recent acquisition of machining facilities has given Gallagher Fluid Seals a wider range of part sizes and tighter tolerances than ever before. Whether it’s a one-inch rotary lip seal or a custom 70-inch backup ring, we now have the tools and expertise to handle complex geometry, exotic materials, and both low- and high-volume production runs.

Here’s a closer look at our machining equipment lineup:

CNC Lathes

HAAS SL-20 (0.090” – 19.00”)
HAAS ST-20 (0.090” – 8.00”)
HAAS ST-30 (1.00” – 20.00”)
HAAS TL-3B Tool Room Lathe (20.00” – 80.00”)

Support Equipment

Manual Mill
Tool and Cutter Grinder
2 Spot Welders (for custom spring welding)
Saws, Comparators, Inspection Gages, and other precision instruments

This range of tooling allows us to machine parts with high repeatability and exceptional surface finish—whether we’re working with filled PTFE, urethanes, elastomers, or metal housings.

Engineering Expertise That Goes Beyond Machining

Machining capacity is only one part of the equation. Just as important is the experience and technical foundation behind it. Gallagher Fluid Seals combines decades of sealing knowledge with modern design software and materials expertise.

Our in-house engineering tools include:

AutoCAD and E-CAD programming software for detailed part modeling and toolpath generation
Comprehensive Spring Energized Seal and Rotary Lip Seal design manuals for optimized performance
Advanced measuring tools and inspection gages to maintain quality from the first part to the last
Full access to both standard and custom PTFE blends, enabling material optimization across a range of applications
Dedicated spring design capabilities, giving us complete control over the energizing components critical to seal integrity

Whether you're developing a new piece of equipment or improving an existing process, our engineering team is here to collaborate, prototype, and deliver.

Strategic Growth with Customers in Mind

Gallagher Fluid Seals has always prioritized long-term partnerships with OEMs, distributors, and maintenance teams alike. With these latest improvements, we’re building on that foundation to serve a broader segment of the industrial market and offer a faster turnaround for both custom and catalog parts.

We’ve also expanded our facility footprint to accommodate future growth, including larger batch sizes and more custom seal programs. And with the sealing industry undergoing significant changes due to new regulations, materials innovations, and electrification trends, we’re committed to staying at the forefront of technology and service.

Our strategic focus going forward is clear:

Expand relationships with large energy and industrial OEMs
Increase our footprint in international markets, especially in Europe
Continue to diversify our supplier base and material offerings
Offer a complete, in-house sealing solution from design to delivery
