Extended Product Information

FAQs

Can these be used for hot water plumbing?

Yes, provided the water temperature does not consistently exceed 212°F (100°C).

Are these safe for fuel lines?

Nitrile is generally compatible with petroleum-based fuels, but check your fuel type for specific chemical compatibility.

What does 70A Shore hardness mean?

It indicates the material's resistance to indentation, with 70A being a standard, medium-soft rating ideal for effective sealing.

Are these O-rings reusable?

While they may remain intact after removal, it is industry standard to replace O-rings whenever a system is disassembled to ensure a proper seal.

Can I use these in an outdoor sprinkler system?

Nitrile is not recommended for long-term outdoor use due to poor resistance to UV light and ozone-related degradation.

Troubleshooting

Seal is leaking shortly after installation

Check if the seating groove was cleaned of old gasket debris or corrosion before installation.

O-ring keeps pinching during assembly

Apply a small amount of lubricant and ensure the O-ring is not twisted in the groove before tightening mating parts.

Visible cracking or hardening

Ensure the application temperature has not exceeded 212°F (100°C), as extreme heat will bake the nitrile rubber.

Pros and Cons

Pros

  • Excellent resistance to petroleum oils and greases
  • High-quality, flexible nitrile material
  • Wide operational temperature range
  • Reliable sealing performance for pressure washers and pumps

Cons

  • Not suitable for outdoor exposure to UV light or ozone
  • Limited to specific temperature thresholds
  • Cannot be used with certain synthetic esters or polar solvents

Setup, Compatibility & Care

When installing these O-rings, ensure the seating surface is clean, smooth, and free of burrs or debris, as sharp edges can cause premature cutting of the rubber. For ease of installation and to prevent pinching, lightly lubricate the ring with a compatible hydraulic fluid or light grease. Avoid overstretching the ring during placement. Store these items in a cool, dark, and dry area away from direct sunlight, as exposure to UV light and ozone can cause the rubber to crack or degrade over time.
