Making rings each day is time-consuming, but I take pride in every step of the process. From start to finish, I make sure each ring is manufactured to precise specifications and properly finished. I value the craftsmanship that goes into every ring I make, and I believe that attention to detail matters.

Every day is an opportunity to grow, learn, and improve. That is what I strive for each day—not just to make a ring, but to make it better than the last.

If you’re in need of a piston ring, be sure to take a look at what we have to offer. We make rings to specific measurements and take pride in getting the details right.

Don’t see the ring you need? Send us your measurements! Please include:

OD (Outside Diameter)
ID (Inside Diameter)
Ring Thickness
Bore Size

We’ll take a look at your specifications and see what we can make for you. Custom rings are made to order, because sometimes the ring you need isn’t sitting on a shelf—you need one made specifically for your application.

"We’re back making rings! Thanks for your patience — last month was family vacations and our 20th wedding anniversary. I work full time and make rings in the evenings after our three kids are in bed, so manufacturing can take up to 15 days before shipment. Our website is live again and ready for orders. Thank you for your business and continued support."
