The M-Nozzle™ Gasket from MPRC.

When it comes to Railcar Manway gaskets, let’s face it: there are too many sizes, thicknesses, and variations to keep track of. How can you tell the difference between a gasket that’s supposed to be 21” x 19” versus a gasket of similar color that’s 21 1/4” x 18 7/8”? In addition, supplier lead times are at an all-time high, making some Railcar gaskets very difficult to get your hands on. So, how do you get the gaskets you need promptly?

It’s frustrating, and we get it. That’s why MPRC developed a simplified solution: One gasket that fits over any standard 20” Nozzle that replaces manway or “top hatch” cover gaskets.  The M-Nozzle™ Gasket from MPRC.  One Gasket- One Answer- ONE SOLUTION.

***SPOILER ALERT: MPRC is working on a new Yellow Viton “B” M-Nozzle gasket at this time (shown below) that we hope to have available for release in the very near future, as we continue to navigate through material shortages and excessive lead times for all Viton materials.  Stay tuned for more updates!***
