O rings banner


Our O‑ring range includes metric and inch sizes to a range of international, national and industry standards, 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 specialised grades for applications such as oilfield, bioprocessing and nuclear - ready for same day despatch.

If the 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.

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.
