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.

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.
