Collection: Metric O-Rings
O-Rings, also known as packing seals, are mechanical gaskets created in the shape of an O, which can be placed into a groove and compressed between two or more parts. Often used in hydraulic cylinders and pump shafts, they are the most common seals used in machinery as they are simple, effective and cost-efficient.
With a high resilience to pressure and a wide variety of sizes available, O-rings are the top choice for most hobbyists on their mechanical projects.

Let customers speak for us
from 52 reviewsExactly as described but without the rip off prices
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.
Excellent service went above what may have been expected on sourcing product.
Excellent service very fast delivery thanks
Easy to use website, easy to order, well packed and fast delivery. What else can you ask for. Excellent
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!
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.
Great service product bang on
All good all round, thank you.
