O-rings and Back-up Rings

O-rings, back-up and buffer rings, and square-profile gaskets.

The O-ring is the most common sealing element: it is compressed between two surfaces and closes the passage. Its simplicity is deceptive — the wrong material or the wrong groove dimension will cause a leak in a short time.

A back-up ring sits next to the O-ring and prevents it from being extruded into the clearance under high pressure. In high-pressure circuits an O-ring is never used on its own; when the back-up ring is left out, the O-ring is sliced within a few cycles.

Material is selected according to temperature and oil: NBR for general purposes, FKM where high temperature and chemical resistance are needed. Hardness (Shore) also changes with the groove and the pressure.

Is it time to replace?

Leakage to the outside at connection points
Slicing or twist marks in the O-ring cross-section (missing back-up ring)
Hardening or cracking of the material — a sign of exceeded temperature
Leakage within the first cycles after assembly — groove dimension or fitting error

What to send us when you order

Manufacturer code, or the dimensions: inner diameter × cross-section diameter
Material and hardness, such as NBR 90 Shore or FKM
Operating pressure — it determines whether a back-up ring is required
Machine model

Cannot find the part you are looking for?

Our inventory is wider than this list and it keeps growing. Send us the part code and we will come back with availability and lead time. Adding the machine model and, if you have one, a photograph of the part will speed things up.
