BlueSpot O-Ring Assortment Set - 225 Piece

Nitrile, also known as Buna-N, is a synthetic rubber commonly used for O-rings due to its good resistance to oil, fuel, water, and many solvents. It is a cost-effective and versatile material for general-purpose sealing.

Nitrile O-rings can be used in moderate pressure applications. However, for very high-pressure systems, additional backup rings or specialized O-ring materials and designs might be necessary.

Measure the inner diameter and the cross-section (thickness) of the groove where the O-ring will sit, or measure the old O-ring if replacing one. The set provides a range of metric sizes to accommodate common fittings.

Yes, nitrile O-rings generally offer good resistance to gasoline and other petroleum-based fuels.

Store the O-rings in their provided case in a cool, dry environment away from direct sunlight, heat, and ozone. This helps maintain their elasticity and prevent premature degradation.

The primary advantage is convenience and cost-effectiveness. Having a wide variety of common metric sizes readily available saves time and money compared to purchasing individual O-rings or sets for specific sizes.

Ensure the correct O-ring size is used for the application. Check that the O-ring is not twisted, pinched, or damaged during installation. Verify that the mating surfaces are clean, smooth, and free from defects. Confirm O-ring material compatibility with the fluid/gas being sealed.

This indicates material incompatibility. The O-ring is likely exposed to a fluid or chemical it cannot withstand. Replace with an O-ring made of a more resistant material suitable for the specific application.

Apply a small amount of appropriate lubricant (compatible with the O-ring material and the system's fluid) to ease installation. Ensure the groove or seating area is clean. If the O-ring is too tight, it may be the wrong size; double-check measurements.
