Railroad Seals and Gaskets for Locomotives and Railcars
High-performance sealing for locomotive fuel, hydraulic, lubrication, and air systems, and for tank car, dry bulk, and intermodal railcars. Engineered for the heat, pressure, and aggressive fluids of rail service.
In the railroad industry, every moving part, every railcar, and every system must be protected throughout the journey. MPRC Products engineers high-performance sealing solutions for these and other harsh operating environments.
Below: why sealing matters across the rail system, the seals we build for locomotives and railcars, and where to find our EMD and GE kits.
Why Railroad Sealing Matters
In the interconnected web of rail operations, a single compromised seal can disrupt the entire system.
The Cost of a Failed Seal
An ineffective seal leads to fluid leaks, pressure drops, and system inefficiencies that escalate into costly downtime, environmental risk, or regulatory violations. A leaking seal on a tank car carrying hazardous materials can trigger substantial cleanup costs and public safety concerns.
What Quality Seals Deliver
- Prevent operational failures and protect cargo integrity
- Maintain system pressure and prevent contamination or leakage
- Reduce unscheduled maintenance and increase uptime
- Extend the lifespan of rail assets and support regulatory compliance
Seals for Locomotives and Railcars
Purpose-built solutions for each environment, so every cargo type, from fuel to food-grade goods, is protected through transit.
Locomotive Sealing
Resistance to extreme heat, high pressure, and aggressive fluids.
- Fuel systems: handle volatile fluids and prevent leaks
- Hydraulic and lubrication systems: withstand high heat and pressure
- Brake and air systems: consistent pneumatic performance
O-rings, gaskets, and dynamic seals in FKM and NBR for thermal and chemical resistance, with EPDM for weather resistance in some pneumatic systems.
Railcar Sealing
Cargo integrity under a wide range of conditions.
- Liquid tank cars: manway, valve, and vent seals compatible with chemicals and fuels
- Dry bulk and intermodal: seals that block moisture and contamination and stay flexible over long hauls
PTFE or FKM for aggressive environments, and EPDM for dependable water and general-purpose sealing.
