Decades of Expertise Solving the Toughest Sealing Challenges

MPRC Products has supported clients across the Electro-Motive Diesel (EMD) market since 1982. Our in-house engineering and development teams have developed sealing solutions using new, innovative, and time-tested materials that deliver dependable results.

Complete Kits Designed for Every EMD Engine Configuration (645, 710, 567)

MPRC helps simplify ordering and logistics with complete sealing kits for EMD engines.

Proven Quality and Short Lead Times—What Sets MPRC Apart

When an EMD locomotive seal is damaged, degraded, or fails outright, the whole train can come to a screeching halt, risking crew and passenger safety, schedule delays, and product loss. From maintaining a large fleet with a nationwide distribution network to avoiding a backup of passenger trains, long lead times for replacement seals simply aren’t an option. MPRC Products specializes in fast delivery cycles for standard and custom components. We regularly maintain two-week lead times (or less!) for the industries we work with, which is a fraction of the two- to three-month lead times common to most OEMs.

The MPRC team delivers when fast service and high-quality seals are critical needs. Our internal team provides detailed quotes and estimated timelines to help our customers facilitate scheduled maintenance and unexpected repairs.

Backed by U.S. Manufacturing and Strict Quality Standards

To guarantee quality, we maintain ISO 9001:2015 and AAR M-1003 certifications, which ensure adherence to industry standards for reliability. Additionally, if needed, we provide complete kits comprising multiple types of sealing products that can meet your particular project needs.

Meeting and Exceeding OEM Material Standards

Every locomotive seal we manufacture is designed to meet or even exceed OEM material standards, with numerous upgrade options available to ensure you get what you need from us.

We utilize various premium materials, including:

• Rubber elastomers that optimize reliability, resistance, and versatility.
• Teflon, PTFE, Nylon, and other polymer materials that combine strength and resistance with cost-effective, lightweight designs and optimal manufacturability.
• Mineral and natural fiber gasket materials and seals for enhanced fireproofing, pressure resistance, and high-temperature insulation.

Shorter Lead Times and Better Support From a Domestic Supplier

Another advantage of U.S. manufacturing for railcar seals is the ability to maximize efficiency through shorter overall lead times. Working with a domestic supplier assures you get solutions when you need them, minimizing potential supply chain disruptions common with globally sourced products.
