Since 1982, Master Packing & Rubber Co. (MPRC) has gained extensive experience as a provider of innovative sealing solutions for hostile operating environments. Our skilled team customizes sealing solutions for virtually any industry or application. We offer significant expertise that allows us to identify unique problems and offer relevant and optimized solutions. The MPRC team incorporates computer finite element analysis into every project to simulate how designs will react under real-world conditions, enabling us to identify and correct design flaws before physical production ever begins.

While many of our competitors only sell out-of-the-box solutions, we know that most jobs aren’t as simple as one-size-fits-all. Our customer service representatives are continuously available to ensure every order meets exact customer needs. We take pride in our ability to provide superior sealing solutions for complex or challenging applications, such as those found across the industrial sector.

Services for Industry

MPRC maintains an experienced engineering team that will develop and customize sealing solutions for use in the harshest industrial settings. We use a high-output, computer-controlled Atom Flash cutter to produce our seals and gaskets, which has virtually eliminated steel rule die cutting from our manufacturing processes. This allows us to grant significant cost savings to our customers since we don’t have to fabricate any tooling in advance. With a ready CAD design, we can often begin production within a few hours.

Our manufacturing process is environmentally friendly, and we can accommodate rapid manufacturing on nearly any order. We also possess in-house rubber molding capabilities, which enables us to customize rubber moldings for specific industrial purposes.

We offer a broad portfolio of products for industrial customers, such as:

  • Boiler gaskets
  • Braided packing
  • Cut gaskets in ASME standards (available in broad variety of materials/thicknesses)
  • Die-formed and Mandrel-formed packing rings
  • Durometers
  • Hydraulic packings
  • Mechanical seals
  • O-rings
  • Spiral-wound gaskets
  • Spray chemicals and tools

Our tables can cut up to 100 feet and include tapering capabilities for adding holes. We offer fast turnaround on every order, as well as 24/7 emergency services. MPRC also offers much lower order minimums than our competitors.
