Good selection at a reasonable price.

I needed an o-ring for my ebike's hydraulic bakes so I ordered a few packs either side of the size i thought i needed. I also noticed that they did a pack of o-rings for hozelock connectors so I ordered a pack as some of mine were leaking.
I haven't had time to try the bike o-ring yet but I have replaced some of my old brittle water butt connector o-rings and they are as new again.
They have a good selection of seals at a reasonable price, my only gripe is that the website is awkward to use. If you add an item to your basket, you can't go back to where you were browsing, you have start from scratch.

Jack back in action.

Exactly what I needed to fix leaky pump shaft on my 3 ton trolley jack. With new O-ring fitted, there is no leak and the jack no longer sinks under load. Didn't really need the full minimum purchase of 20 O-rings but at least I can fix the jack another 19 times!

Great quality FKM O-rings

Fast delivery and very good quality Viton/FKM O-rings. Material feels strong and high temperature resistant. Unfortunately I ordered the wrong size for my Audi coolant pipe repair, but the product itself is excellent. Would buy again.

What is a Nitrile O-Ring?

A synthetic rubber material that is extremely versatile, nitrile (NBR) is used for seals due to its ability to resist common chemicals including petrol, oil, acid and alkalines. This makes it the perfect choice for automotive components, as it is usually used for fuel tanks components and any other seals that are constantly in direct contact with fuel.

Nitrile is also perfect for medical devices, as it causes less allergic reactions to common substances such as latex and rubber.

Why use a Nitrile O-Ring?

Nitrile (NBR) O-Rings are popular for their durability, especially in applications requiring resistance to oils, fuels, and certain chemicals. They offer a reliable, cost-effective sealing solution for various industries, including automotive, aerospace, and manufacturing. With excellent wear resistance and the ability to handle temperatures from -40°C to +120°C, Nitrile O-Rings ensure a long-lasting, secure seal in demanding environments.

How do I choose the right size o-ring?

To select the correct size Nitrile O-Ring, start by measuring the internal diameter (ID), outer diameter (OD), and cross-sectional thickness. These measurements will help you determine a proper fit, ensuring an effective seal. It’s essential to consider factors like pressure, temperature, and the type of material it will come into contact with, as these can impact the performance and longevity of the O-Ring. For guidance on specific sizes or custom requirements, refer to our size charts or reach out to our team for assistance.
