You can find the products we design, manufacture, and distribute all over—and even off—the planet

Eclipse Engineering was the brainchild of a passionate, business-minded engineer. His goal was to provide answers to seal and bearing questions to a niche market. Since operations began in 1999, Eclipse has evolved into a comprehensive partner for many OEM, MRO and industrial customers around the world. These companies have come to count on our engineered solutions, problem solving skills, in-house manufacturing capabilities and the responsiveness associated with distribution.

Our staff has more than 200 years of combined seal and bearing experience. This experience allows us to determine if a standard off the shelf product can be used or if an engineered solution will be required for an application.

At Eclipse, we've designed seals:

In reciprocating, oscillating, rotary and static applications

That work in applications in excess of 500K PV

To maintain extreme vacuum

To withstand 100K PSI

To contain radioactive water, fire resistant hydraulic fluid, H2S, solvents, and more

As a top tier supplier, we strive to continually improve our processes, while keeping with the essential principle of providing, foremost, engineering and technical assistance that results in an optimized solution for your sealing application.

From our sales professionals to our engineers, we take pride in the fact that we listen to our customers' needs and provide them with quality products—at a competitive price, in a timely manner.

What Our Customers Have to Say

When it comes to engineering and manufacturing seals, customer satisfaction is everything. From initial communications to the quality of the products we deliver, we always aim to be the best. Want proof? Read what some of our customers have to say about working with us!

We’ve been a customer of Eclipse Engineering for many years and have found them to be a very reliable source for products. They are very supportive of our stocking program on some special wear bands they have made for us. Barry has been especially helpful over the years in finding sources for other items i.e. loaded lip seals, EC121 tubing, gaskets, etc. I would recommend them as a viable source for many applications.

Eclipse Engineering, Inc has been a reliable key partner in our production process. I can always rely on having what I need available and delivered (Thank you Barry!) when I need it. Recently I was out of the country and received a desperate message from my production supervisor that we had unexpectedly run critically low on a component. All it took was 1 email to Eclipse and Barry had what we needed delivered and saved our production deadlines.


Eclipse supplies our company with a range of products from seals to O-rings. We have worked with them over the last 8-10 years. They have a engineering capability that has helped us with some parts that needed redesign and updating. Barry has always been very responsive when we had a question or issue.
