An O-ring is a circular seal typically made of an elastomeric material, such as rubber. It is designed to create a reliable and flexible seal between two adjacent surfaces, preventing leakage or penetration of liquids or gases.

O-rings are used in a wide range of industries and applications due to their versatility and efficiency. Some important reasons for using O-rings include: 

1. Sealing ability: O-rings provide an effective sealing solution by filling the gap between two adjacent surfaces and creating a tight seal. They can withstand pressure differences and prevent the leakage of liquids or gases, ensuring the integrity and efficiency of the system.

2. Versatility: O-rings come in different sizes and materials, making them adaptable to different applications and environments. They can be tailored to meet specific requirements, enabling a wide range of sealing solutions.

3. Cost-effective: O-rings are relatively inexpensive compared to other sealing options, providing a cost-effective solution for sealing applications. They are widely available and can be easily replaced when needed, reducing maintenance costs.

4. Easy Installation: O-rings are easy to install and require minimal tools or expertise.

5. Fluid and temperature resistance: O-rings are designed to withstand a variety of fluids, including water, oils, fuels, chemicals and gases.

6. Longevity and durability: O-rings are known for their durability and longevity. When properly selected and maintained, they can withstand continuous use, cyclical movements and various environmental conditions without significant deterioration.

We have nearly 40 years of experience in providing high quality O-rings. We have access to thousands of standard dimensions that are often only a few weeks away from delivery, but we are exceptionally competitive with non-standard o-rings as we have no MOQs and rarely tooling costs.

Historically, we have supplied o-rings as small as under 1mmID up to over 3000mmID, with cross-sections under 1mm up to 15mm.

We offer full traceability, in-house & independent lab testing. Coverings (eg silicone oil, PTFE, etc.), identification with a coloured dot, and conductive (EMI/EMC) o-rings.
