These 18mm ID, 24mm OD nitrile rubber O-rings are ideal for mechanics, DIY enthusiasts, and engineers looking for a reliable, oil-resistant seal for cylindrical mating surfaces. They provide excellent fluid containment in pressurized environments like engines and hydraulic systems, though users should be aware that the material is not suitable for high UV exposure or specific solvents like acetone.

Yes, nitrile rubber is generally compatible with petroleum-based fuels and oils.
Yes, their 70A Shore hardness makes them capable of handling standard hydraulic sealing requirements.
While they are effective, nitrile is primarily engineered for oil resistance; they will perform adequately for standard water plumbing applications.
It is a measurement of the rubber's hardness. A 70A rating is considered semi-rigid, providing a good balance between flexibility for sealing and resistance to being cut or penetrated.
Only if the storage area is dark and free of ozone-producing motors or UV light, as these elements degrade nitrile rubber over time.
Verify the groove dimensions are correct for a 3mm cross-section and check that the mating surfaces are not pitted or damaged.
Apply a small amount of system-compatible lubricant to the O-ring and the groove to assist with smooth seating.
To ensure a lasting seal, ensure the mating surfaces are clean and free of metal burrs or debris that could nick the nitrile rubber. When installing, use a light coat of compatible lubricant to prevent the O-ring from twisting during the tightening process. Avoid stretching the ring beyond its elastic limit. Regarding care, store these rings in a cool, dry place away from direct sunlight or ozone-generating equipment to prevent degradation. Do not use these seals in systems carrying acetone, ketones, or esters, as these chemicals will cause the nitrile material to fail prematurely.
