The Sealey BOR407 407-piece imperial O-ring kit is an essential utility pack for automotive technicians, professional plumbers, and DIY enthusiasts who require reliable sealing solutions for a wide range of mechanical applications. This assortment provides high-quality Buna-N rings in numerous imperial sizes, ensuring that you have the correct seal on hand to prevent fluid leaks or gas escapes during repairs. While the set is highly comprehensive, users should note that the rings are manufactured specifically to imperial standards and may not be suitable for applications requiring metric-specific sizing.

These O-rings are manufactured from Buna-N, also known as Nitrile rubber, which is highly resistant to oils and fuels.
This kit consists entirely of imperial-sized O-rings.
Buna-N has standard temperature tolerances. Please check your specific application requirements, as it may not be suitable for extreme high-heat engine components.
Yes, the kit comes in a partitioned, interspaced box designed for easy organization.
The set includes diameters ranging from 1/8 inch to 2 inches with thicknesses from 1/16 inch to 1/8 inch.
While Buna-N is versatile, you should verify if the specific grade is certified for potable water use if your project involves drinking water lines.
Verify that the ring is the correct size; if the ring is too loose, it will not seal, and if it is too tight, it may have been stretched or pinched during installation.
This indicates chemical incompatibility or heat degradation; confirm the application temperature and fluid type are within the tolerance of Buna-N material.
Use a sizing cone or a digital caliper to measure the inner diameter and cross-section thickness to match against standard imperial sizing charts.
To ensure optimal performance, verify the size of the groove where the O-ring will be placed using a digital caliper before selecting a replacement from the kit. Ensure the sealing surface is free of debris, rust, or old adhesive before installation, as these can cause premature failure. To maintain the life of your O-rings, store the kit in a cool, dry place away from direct sunlight, as UV exposure can degrade rubber over time. When installing, use a small amount of compatible lubricant to prevent pinching or tearing the ring during the seating process.
