The O-Ring gland (also known as O-Ring groove) is a very important design feature for anufacturing both efficient and cost-effective O-Rings.
The most important consideration for gland design is that it allows for proper and complete compression between the groove and the mating surface. While the shape of the O-Ring relies and depends on the application, shape is generally unimportant. The groove can be a variety of shapes; anything from triangular, rectangular, or dovetail.
O-rings are the most common sealing product in the world; utilized across all types of sealing applications and industries. At its core, an O-ring is a circular sealing element with a circular cross section. Used effectively, an O-ring can seal practically all fluid, both liquid and gas. The wide range of potential liquids and gases that need to be sealed has necessitated the development of a wide range of materials.
GFS O-rings are manufactured in accordance with metric and imperial standards, such as: AS568, DIN, ISO 3601 and JIS. Additionally, O-rings can be manufactured to custom sizes upon request. Below are some of the most popular metric O-ring materials and durometers.
Spring Energized Seals are designed for applications with high pressures and temperatures, cryogenic fluids, extreme media and other service conditions which exceed the performance characteristics of O-rings and conventional elastomeric seals.
We introduced our Spring Energized Seal guide in 2016 are we're happy to share that it's now available for FREE to download.

For immediate release
East Longmeadow, MA | October 25, 2023 – Gallagher Fluid Seals is expanding! We are pleased to announce the grand opening of our new state-of-the-art warehouse in East Longmeadow, MA.
This new 15,000 square foot warehouse located at 142 Denslow Road is a climate controlled, energy efficient space which will store gaskets, O-rings, sheet material, braided packing, and a variety of other fluid seals for key customers.
With the new warehouse, Gallagher is expecting 26% staff growth in both its adjacent fabrication facility (136 Denslow Rd) and 142 Denslow.
Global leader and manufacturer of specialty chemicals and natural materials. Their product line includes a variety of additives and chemicals such as: monomers and polymers, surfactant blends, polyglucosides, and oils.
Customer experienced an issue on their RV-7 dryer in a chemical application; their food grade compression packing was flaking, causing white specs, fibers, and flakes in the end product, which caused equipment maintenance and unplanned downtime.
Through testing and evaluation with a site visit
Gallagher Fluid Seals has published our newest sizing guide, the DIN 3771 O-Ring sizing chart.
Standards such as AS568, BS 1806, DIN 3771, JIS B2401, NF T47-501, and SMS 1586 were developed by national standards organizations to satisfy the needs of their national industries.
The DIN 3771 o-ring standard is issued by The German Institute for Standards (Duetsches Institut für Normung). This standard identifies O-Ring sizes by the Inner Diameter x Cross Section.
In this sizing chart, you will find both metric and actual data regarding the size of each O-Ring in the standard.
For information about how to interpret or read this chart, feel free to contact Gallagher Fluid Seals.
Leading manufacturer of reliable filter & distillation technology for pulp & paper, chemical and petrochemical, and semiconductor applications. Their membrane technology helps to reduce load on energy-consuming evaporators or distillers.
