For over 40 years, Master Packing & Rubber Co. (MPRC) has provided high-quality sealing solutions for diverse industrial applications throughout Eastern Iowa and beyond.
Serving Eastern Iowa Customers with Industrial Sealing Solutions
At our headquarters in Cedar Rapids, our experienced engineering team develops custom seals, gaskets, and O-rings that stand up to the most challenging environments. Using advanced materials and reliable processes, we create products that tolerate high temperatures, pressure extremes, vibration, corrosion, and even improperly applied clamp loads. MPRC designs and manufactures innovative sealing solutions for a diverse range of industries and applications, including:
- critical components
- expansion joints
- piping systems
- pumps of all types
- valves.
Whenever possible, we reference original equipment manufacturer (OEM) part numbers to ensure reliable compatibility. From heavy machinery to material processing and manufacturing, MPRC industrial seals enhance the efficiency and service life of essential equipment with custom sealing solutions.
Why Choose MPRC?
At MPRC, our entire team is committed to developing efficient and innovative sealing solutions for companies throughout key industrial hubs in our region, including Cedar Rapids, Iowa City, Davenport, and Dubuque. We will work with you to provide excellent customer service and to make sure your order meets your expectations and requirements.
Unlike off-the-shelf or one-size-fits-all sealing products, MPRC understands each application has physical, operational, or environmental requirements that can’t be met with generic solutions.
Our in-house engineering team uses finite element analysis (FEA) to simulate real-world conditions, potential material or manufacturing problems, and other challenges. This allows us to refine designs prior to full production, reducing waste and giving you a better end result, such as:
- Optimal sealing performance
- Reduced maintenance costs
- Less operational downtime
- Proactive correction of design flaws
Comprehensive Material Selection and Manufacturing for Sealing Solutions
We use a variety of manufacturing processes to make seals, including lathe cutting, molding, extruding, and splicing. We also have several computer-controlled, high-output Atom Flash cutters for precision cutting, which provides superior results to traditional die-cutting. Our facility is outfitted with cutting tables that extend to 100 ft. and tapering capabilities that ensure precision hole placement. All of this gives us great range in the kinds of materials and products we can produce.
We also work with a large selection of materials for many different industrial applications. Options include natural rubber, neoprene, nitrile, silicone, cork, metal, EPDM, and PTFE. We stock many kinds of roll and sheet materials. In addition, rapid prototyping services are available to help test and refine sealing solutions for new applications.
With state-of-the-art technology, high-quality materials, and in-house expertise, we can provide custom seals that are cost-effective and quick to produce. We also maintain low order minimums and provide around-the-clock emergency services to accommodate our customers’ needs.
