This Sealey 407-piece Rubber O-Ring Assortment is designed for mechanics, plumbers, and DIY enthusiasts who need a reliable supply of imperial-sized O-rings for repairs and maintenance. Its key benefit is providing a wide range of sizes in a organized case, ensuring you have the right O-ring for most common applications. A caveat is that the material is either Nitrile or Buna-N, which may not be suitable for all chemical or high-temperature environments.

The O-rings are manufactured from either Nitrile or Buna-N rubber. The specific material variant is indicated on the product packaging.
Nitrile O-rings generally withstand temperatures up to 120°C, and Buna-N up to 100°C. For applications exceeding these temperatures, a different material may be necessary.
They are generally compatible with petroleum-based oils, fuels, water, and some hydraulic fluids. They are not suitable for strong acids, ketones, esters, or brake fluids (unless specifically stated for Buna-N).
The set contains approximately 407 O-rings. The exact count can vary slightly due to the bulk packaging method.
Yes, the O-rings are supplied in a partitioned, interspaced box for organization and storage.
These are imperial-sized O-rings. While some metric sizes might be coincidentally close, they are designed for imperial measurements and may not provide a perfect seal in metric applications.
Store the O-rings in their original partitioned box in a cool, dry place away from direct sunlight and sources of heat to maintain their integrity.
Ensure the correct size and thickness O-ring has been selected for the groove. Check that the mating surfaces are clean and free of debris. Verify that the O-ring material is compatible with the fluid or gas it will encounter.
Lubricate the O-ring and the groove with a compatible lubricant (e.g., silicone grease or a drop of the system fluid). Avoid using excessive force, which can damage the O-ring. Ensure there are no burrs or sharp edges on the component.
Check if the O-rings are exposed to temperatures or chemicals beyond their compatibility range. Ensure they are stored correctly away from UV light and extreme temperatures. Consider if a different O-ring material is required for the application.
Setup: The O-ring assortment comes ready for use in its partitioned storage box. Simply open the box and select the required O-ring.
Compatibility: This assortment contains O-rings in imperial sizes, manufactured from Nitrile or Buna-N rubber. These materials are generally compatible with petroleum-based oils, fuels, water, and some mild chemicals. They are typically not recommended for use with high temperatures (above 120°C for Nitrile, 100°C for Buna-N), strong acids, ketones, or esters. Always verify the specific requirements of your application to ensure material compatibility.
Care: Keep the O-rings in their original partitioned box to protect them from dust, dirt, and UV light, which can degrade the rubber over time. Store the box in a cool, dry place. Inspect O-rings before use for any signs of damage, cracks, or deformation. Clean any components before installing a new O-ring.
