Finer Power NBR 70 O-Ring, inside diameter - id (mm) 12.5
The price shown is for the pack.
Available
NBR (nitrile rubber) 70 durometer metric O-rings with a 1mm cross section.
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 MOR12X1 is 12mm inside diameter by 1mm 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, 1.5mm Cross Section, 1.5 to 50mm ID; NBR 70 O-Ring, Metric, 1.6mm Cross Section, 14.1 and 15.1mm ID; NBR 70 O-Ring, Metric, 2mm Cross Section, 1 to 100mm ID; NBR 70 O-Ring, Metric, 2.5mm Cross Section, 3 to 49mm 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.
