Seals & O-Rings

Seals and O-rings are used to join two parts of a machine, engine or other mechanical assembly by filling the space between both parts, creating a filled and seal space in between. This seal prevents particle, vapour and fluid leakage to protect and maintain pressure whilst keeps debris out, ensuring proper function and safety. Seals and O-rings are used in various fields and industries including automotive, aerospace and general engineering.

How do seals and O-rings work?
A seal or O-ring is seated in a groove in one of the two parts to be joined then compressed between these two components to the corresponding groove creating a securely sealed joint. They can be used in dynamic joints where there is movement as well as in static or fixed applications.

Types of seals and O-rings
Seals and O-rings come in various materials suited to different purposes. Some have a high temperature tolerance for use in both hot and cold applications, while others are made to be chemically resistant for use in lab or test equipment. Available in a wide range of sizes both in single size packs or in seal and O-ring kits for general maintenance or when looking after a range of sealed part to ensure the correct size is available.

Seals and O-rings are typically made of elastomers like nitrile rubber and silicone, but they also come in plastics, metals and other materials. This variety of material allows for specific seal and O-rings to be used to ensure the best fitting and most reliable seal.

Sizes vary between seal and ring types both in diameter and thickness, these variations help provide an exact and precise seal to protect the joint. Both Metric and Imperial sizes are available to replace new and old seals and rings whether maintaining modern parts or older machines, engines and other mechanical parts.
