The uxcell Nitrile Rubber O-rings are essential components for DIY enthusiasts, mechanics, and maintenance professionals who need a reliable seal for hydraulic or pneumatic systems. These 31mm OD rings excel at preventing leaks in engines, valves, and cylinders, providing a durable barrier against petroleum-based fluids. While these rings are highly resistant to oils and grease, they are not suitable for high-heat environments exceeding 212°F (100°C) or exposure to specific aggressive solvents that degrade nitrile rubber.

These are made from high-quality Nitrile Rubber (Buna-N), which is known for its excellent oil resistance.
While they provide a good seal for general fluid applications, they are optimized specifically for petroleum and hydraulic fluids.
It refers to the material's durometer (hardness). 70A is a standard hardness that provides a good balance between seal integrity and elasticity.
It is generally recommended to replace O-rings after they have been compressed in an assembly, as the material can take a permanent 'set' over time.
No. These are rated for a maximum of 212°F (100°C) and will fail rapidly if exposed to exhaust temperatures.
Check for debris in the seating groove or nicks on the mating metal surfaces.
Apply a small amount of compatible silicone-based lubricant to assist in seating the ring.
Replace the O-ring immediately, as this indicates it has exceeded its service life or temperature limits.
Before installation, thoroughly clean the groove or mating surface to remove old gasket residue, dirt, or metal shavings. Lightly lubricate the O-ring with a compatible lubricant to prevent twisting or tearing during insertion. Verify that your groove dimensions match the 3mm cross-section size to ensure proper compression. Keep these rings stored in a cool, dark place away from direct sunlight, as UV exposure can degrade nitrile rubber over time, leading to cracking and reduced sealing performance.
