EMD Locomotive Seals, Gaskets & Complete Kits
Replacement seals, gaskets, and ready-to-install kits for Electro-Motive Diesel 645, 710, and 567 engines. Engineered and manufactured in Cedar Rapids, Iowa since 1982.

EMD locomotive engines operate under extreme heat, pressure, and vibration, and every fuel, lubrication, cooling, and air system on the unit depends on a seal that holds. MPRC Products has supported the Electro-Motive Diesel market since 1982, engineering replacement seals, gaskets, and complete sealing kits for 645, 710, and 567 engines from our ISO 9001:2015 and AAR M-1003 certified facility.
Below you will find how our EMD kits and individual components are configured, which engine models and part numbers we support, and why railroads and rebuild shops rely on MPRC for fast, dependable sealing solutions.
Complete Kits for 645, 710, and 567 Engines
A locomotive rebuild stalls the moment one gasket is missing. MPRC kits contain every seal and gasket required for the job, organized by engine model and application, so technicians are not sourcing individual part numbers mid-overhaul. Kits meet or exceed OEM material requirements and are available with material upgrades for rail, marine, and power generation configurations.

Individual EMD Seals and Gaskets
Beyond kits, MPRC manufactures the individual components that keep an EMD unit in service:
- Cylinder head gaskets, head frame gaskets, and cylinder head seat rings
- Turbocharger, exhaust manifold, and aftercooler gaskets
- Water pump, oil pump, and cooler gaskets
- Fuel, hydraulic, and lubrication line seals
- O-rings, grommets, and dynamic seals in FKM, NBR, EPDM, and PTFE
- Custom-cut gaskets from your drawing or sample, in metal, graphite, rubber compounds, and specialty CG formulations
Materials Built for Locomotive Service
Every system on a locomotive has its own sealing demands. MPRC selects materials for the service, not the catalog.
- FKM and NBR for thermal and chemical resistance in fuel, hydraulic, and lubrication systems
- EPDM for weather-exposed brake and pneumatic systems
- PTFE and flexible graphite where temperature and chemical attack rule out elastomers
- Forgiving designs engineered to hold on flanges that are no longer in perfect condition
Why Railroads Choose MPRC Products for EMD Sealing
When an EMD seal fails, the whole train stops. MPRC is built to get it moving again.
100% In-House Manufacturing
Every seal and gasket is made in our Cedar Rapids, Iowa facility. No outsourcing, no offshore lead times.
Fast Turnaround
Two- to three-month OEM lead times are not an option when a unit is down. We regularly ship standard and custom components in two weeks or less.
ISO 9001:2015 & AAR M-1003
Certified quality systems built for the rail industry, with materials that meet or exceed OEM requirements.
