About us

MJ Produkte^® - Automotive seal and repair kits

Founded in 2014, we have been offering improved seal and repair kits for selected vehicle components whose inner parts tend to wear out quickly and force the customer to replace the entire component instead of just the worn out part itself. Working with retailers and repair shops as well as using our own online shops, we were able to provide more than 30,000 customers all around the world with our products. We work exclusively with our trusted suppliers and manufacturers in order to guarantee high quality and a long service life and have all of our custom seals manufactured in Germany.

We have always been focusing on high-quality, long lasting products. We achieve this by using high-tech materials such as Viton® and PTFE that are custom tailored to the individual application as well as specifiying finer tolerances for CNC produced seals than what most companies work with. We subject every new product that we devise and develop to extensive testing before selling it to our customers. We strive to far exceed OEM materials and specifications whenever possible. 

That "made in Germany" is still regarded as a synonym for high-quality automotive products is reflected in our international sales which make up more than 32% of all sales (2014 - 2023, data rounded).

In 2023 we moved operations to the United States and are now operating as the MJ Products LLC in Idaho. In an effort to meet our customers' high expectation of quality, we continue to have all of our custom seals and parts manufactured in Germany and import them into the United States.

Currently we plan to expand our product portfolio for the US market and add products for Buick, Cadillac, Chevrolet, Chrysler, Dodge, Ford, GMC and Ram.
