Both positions would involve walking/standing, lifting (up to about 50 Lbs), performing tasks on a computer, reading a tape measure, operating various types of machinery, and the ability to perform repetitive functions for an entire day. We offer competitive wages as well as health insurance and an IRA. We will train you into the position, so a willingness to learn is key.

MPRC's previous edition of our Cylinder Head Gasket with yellow grommets has often been copied. Though we understand that copying is one of the biggest forms of flattery, the real issue is quality and performance when it comes to a critical sealing component of the engine. The fact is, it's easy to copy a color, but it's not about the color choice of a grommet in your Head Gasket- it's about the COMPOUND. The material must be able to withstand proper temperatures and mechanical torque, or failure is inevitable.
Use a trusted source for all your Rail, Marine, and Power Generation Engine needs- MPRC. Quality products designed, engineered, and made with the highest-quality materials. Veteran-owned and trusted since 1982.
