O‑rings and elastomeric seals

Our extensive portfolio of high performance, high pressure O‑rings includes metric and inch sizes to a range of international, national and industry standards.

High performance O-rings

James Walker specialises in high-performance O-rings, manufactured in a variety of general and high performance elastomers to suit the vast majority of industrial and specialised applications.

The seemingly humble O-ring, or toroidal seal, is an exceptionally versatile sealing device. Applications ranging from garden hose couplings to critical aerospace or oil and gas duties make it the world's most popular volume produced seal.

We have been making top-quality O-rings since this sealing method was introduced in the 1930s. Today we stock many thousands of types and sizes in our most popular materials - including high pressure O-rings and specialised grades for applications such as oilfield, bioprocessing and nuclear - ready for same-day despatch.

If the O-rings you want are not available off-the-shelf, with our 'lean' manufacturing plant and flexible production schedules, we can often precision manufacture them within hours if necessary, to meet the most urgent of requests.

Bespoke seals and custom O-rings

At James Walker, we deliver custom sealing solutions and bespoke O-rings to meet the needs of a broad range of specialised applications.

We create bespoke seals that adhere to an extensive range of international, national and industry standards, with a focus on high-performance and high-pressure environments. We make use of a combination of general and high-performance elastomers, to create custom O-ring and sealing solutions specifically engineered for the most demanding applications.

Our advanced manufacturing capabilities and flexible production schedule allow us to offer precision-manufactured, bespoke O-rings.

Working under tight time constraints? Let us know your deadline, and we will work to turn around your bespoke order to meet your schedule, potentially within hours.

Our technology


Whilst a decision on the proposed PFAS regulation, and the likely timeline for implementation, are still being considered by the ECHA, James Walker is proactively looking at, and qualifying, alternative materials and working with its suppliers to ensure sealing materials are available that will offer the required levels of performance and be compliant with any proposed regulations.
