Why Eclipse Engineering Exceeds as Your Seal Distributor

Cliff • February 6, 2019

At Eclipse, reliability is not an accident. Our customers’ expectation is that each seal we design and manufacture is to print, and meets the quality requirements that are specified. 

Quality and reliability are part of who we are. Our culture at Eclipse Engineering is to place our customers at the center of our purpose. If we succeed in satisfying our customer, we will succeed in our goals.

Seals are always a part of a system to retain or exclude a fluid. A method for improving reliability is creating sub-assemblies, or cartridges, which retain the seal with other components.

Installation is improved because there’s little or no chance of seal damage. And field replacement can be accomplished by cartridge replacement again, allowing for improvement of repaired units without risk of seal damage.

Single Source for All Components

At Eclipse, we often source all the components, build the seals and build up the sub assembly. This reduces part count for the OEM, reducing the overall cost of the end product due to sub assembly build up and installation.

We Handle Repackaging and Reselling

We can also package for resale of our OEM’s, preparing the product to move from the shelf into the rebuilder’s hands, with a high probability that the rebuild will be successful.

Eclipse prepares kits for OEM resale into the rebuild market, saving time and resources by pulling all the soft replaceable components for seal rebuild. We can manage the purchasing of all the components and brand package for resale.

O-Rings can be dotted or individually packaged, or tagged for easy identification for the end customer during their build cycle.

As an authorized DuPont Kalrez distributor, we can supply genuine Kalrez products in their original packaging. They can be supplied individually or packaged in kits for resale.

Certification, Delivery and Inventory Maintenance

Certification of products is available depending what the requirements are.
Products can be dropped shipped anywhere in the world.

We also can plan delivery and maintain inventory to smooth out manufacturing insuring products will always be available regardless of the production schedules.

Reliability, delivery, quality, and price will continue to be our customers focal point. Contact us today with any customer service question or need »

The Different Types of Seal Glands and How to Choose the Right One

By Doug Montgomery • October 21, 2026
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
