  • Confirm Size & Material — Measure your existing O-ring or groove dimensions. Ensure nitrile rubber (NBR) is suitable for your application before purchase.
  • Remove Old Seal — Carefully extract the worn or damaged O-ring from the fitting or pipe, clean the groove thoroughly to remove debris.
  • Install New O-Ring — Lubricate lightly with compatible grease, then press the new Buna-N O-ring into the groove, ensuring a snug fit without deformation.
  • Test & Reassemble — Turn on water or pressure system, check for leaks. Reinstall fittings securely. Replace every 1-2 years or if leaks reappear.

FAQ, See What Others Asked

What is the difference between nitrile (NBR) and Viton (FKM) o-rings?
Nitrile o-rings are cost-effective, suitable for water and oil sealing at moderate temperatures. Viton handles higher heat and chemicals, ideal for demanding environments. Match material to your application's temperature and chemical exposure.
How do I choose the right o-ring size?
Measure the inner diameter and cross-section of your fitting. Confirm whether the size follows metric or AS568 standards. Select an o-ring that matches these measurements for a proper seal.
Are these o-rings safe for plumbing in India?
Yes, these nitrile rubber o-rings are suitable for Indian plumbing systems, resisting oil, water, and UV exposure. They are factory-sealed and imported from the USA for reliable performance.
Can I use these o-rings in high-pressure applications?
These O-rings are designed for standard plumbing and mechanical uses. For high-pressure or chemical-critical systems, consider specialized seals. Always verify compatibility with your system's pressure and fluid type.
How long will these o-rings last in Indian conditions?
With proper installation and maintenance, nitrile o-rings can last 1-2 years in typical Indian environments, resisting UV, heat, and weathering. Replace if signs of wear or leaks appear.
