Key specifications

Selecting and fitting

Choose the O-ring from the groove it fits: the inside diameter, the cross section and the part number. To match an existing O-ring, measure the cross section with calipers and the inside diameter with the O-ring relaxed, then pick the closest part number.

Other metric cross sections are listed under NBR 70 O-Ring, Metric, 3 mm Cross Section, 3 to 150 mm ID; NBR 70 O-Ring, Metric, 2.5 mm Cross Section, 3 to 49 mm ID; NBR 70 O-Ring, Metric, 2.5 mm Cross Section, 50 to 150 mm ID; NBR 70 O-Ring, Metric, 3.5 mm Cross Section, 5 to 150 mm ID. For a size that is not stocked, NBR 70 O-Ring Cord, Metric, 1.5 to 16 mm Diameter can be cut and joined to make a seal for a non-standard groove.

Nitrile rubber suits many oils, fuels and hydraulic fluids. Check that the fluid and the operating conditions suit nitrile before fitting. The catalogue does not list a temperature range for these O-rings, so contact AIMS if temperature is critical.

The inside diameter and cross section are the measured dimensions with tolerances as listed in the manufacturer catalogue.

Dimensions are as listed in the manufacturer catalogue and are for reference. Contact AIMS to confirm a measurement if it is critical to your application.
