Eclipse Engineering “On the Move”

Cliff • July 9, 2010

After 11 years in beautiful downtown Broomfield Colorado, Eclipse has finally moved to a permanent home.

Eclipse Engineering started out in an expansive 1750 Sq ft facility on Industrial Lane in 1999. At the time I thought of renting out some of the space as it seemed too big for our needs. In 2001, we purchased the soft seal side of Jemco Seal. Jemco was primarily a Colorado business and with that acquisition, we nearly doubled in size causing us to increase our floor space.

With our lease up, and the real estate market being what it was, we purchased a building in Erie, Colorado. We moved into a space a bit larger than before with the opportunity to expand 3 fold.  The Building is located “in the country” with a great view of the Front Range Colorado Rockies. We also are located at the Erie Airport, so if you want to fly in to visit, you could taxi up to the back door.

Your support over the past 11 years has allowed us the opportunity to continue to grow and better serve you.

Like any move, it always looks a lot better after the fact. We are still in the throes of re-building and improving our infrastructure. I’m guessing another 5 months or so ought to get us moved in. Until then, it seems every day we move something else.

At the same time we are increasing the number of operations we perform in house, allowing us to better serve your immediate needs.

Eclipse has built its business on responsiveness to the market place.  While we realize you have a choice in purchasing product, our goal is to make the decision a delightful experience working with us.

Thank you again for you support over the last decade.

When designing a successful sealing system, factors such as leakage control, wear resistance, and seal material selection often receive the most attention. However, another critical component can have just as much influence on performance: the seal gland. A seal gland, also referred to as a groove, is the space within the hardware that houses and retains a seal. Its design affects not only how the seal functions but also how easily it can be installed, removed, or replaced. Different seal materials and configurations require different gland designs. For example, an elastic O-Ring may be relatively easy to install in a solid gland, while a PTFE spring-energized seal may require a split or stepped configuration to prevent damage during installation. Understanding the different types of seal glands is essential when selecting a sealing solution. Below, we'll explore four common gland designs, their advantages and limitations, and the seals best suited for each. What Are the Four Main Types of Seal Glands? The four common types of seal glands used in rod and piston sealing applications are solid, open, split, and stepped glands. Each offers different benefits depending on the seal material, installation requirements, and hardware configuration. Solid glands feature a simple rectangular groove and are commonly used with O-Rings and certain O-Ring energized PTFE seals. Open glands allow seals to be installed directly into a counterbore and are typically best suited for metal-cased seals, including rotary lip seals and cased spring energized seals. Split glands use a removable retaining component to simplify seal installation, removal, and maintenance. They are particularly useful for spring energized seals and applications requiring frequent seal replacement. Stepped glands incorporate a small retaining step that secures the seal without additional hardware. They are often used in spring energized sealing applications where a one-piece hardware design is preferred. Choosing between these designs involves balancing installation requirements, manufacturing complexity, and long-term seal performance. Solid Glands
