Finer Power NBR 70 O-Ring, inside diameter - id (mm) 30
Available
NBR (nitrile rubber) 70 durometer metric O-rings with a 5mm 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 MOR76X5 is 76mm inside diameter by 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, 4mm Cross Section, 4 to 150mm ID; NBR 70 O-Ring, Metric, 6mm Cross Section, 50 to 150mm ID; NBR 70 O-Ring, Metric, 3.5mm Cross Section, 5 to 150mm ID; NBR 70 O-Ring, Metric, 3mm Cross Section, 3 to 150mm 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.
