The price shown is for the pack.
Available
NBR (nitrile rubber) 70 durometer metric O-rings with a 2.5mm cross section. This page covers the NBR 70 O-Ring, Metric, 2.5mm Cross Section, 3 to 49mm ID, available in 54 inside diameter - id (mm) options: 3, 4, 5, 5.5, 6, 6.5, 7, 8 and 46 more.
An O-ring seals a joint by sitting in a groove and being squeezed between two surfaces, and nitrile rubber is a common choice for oils, fuels and hydraulic fluids. The part number reads MOR, the inside diameter, X and the cross section, so MOR24X2.5 is 24mm inside diameter by 2.5mm cross section. Measured dimensions and tolerances come in each part number.

Choosing the right option
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 under NBR 70 O-Ring, Metric, 2.5mm Cross Section, 50 to 150mm ID; NBR 70 O-Ring, Metric, 2mm Cross Section, 1 to 100mm ID; NBR 70 O-Ring, Metric, 3mm Cross Section, 3 to 150mm ID; NBR 70 O-Ring, Metric, 1.6mm Cross Section, 14.1 and 15.1mm ID. For a size that is not stocked, NBR 70 O-Ring Cord, Metric, 1.5 to 16mm 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.
