Installation tips & best practices
- Always match the O-ring inner diameter and cross-section thickness to the original part for a proper seal.
- Lubricate O-rings lightly with compatible lubricant (silicone grease or application-specific lubricant) to prevent twisting or tearing during installation.
- Inspect sealing surfaces for scratches or debris — a clean groove ensures a longer-lasting seal.
- Avoid sharp edges and use plastic tools when possible to reduce the risk of nicking the O-ring during fitting.
- Store O-rings away from direct sunlight and harsh chemicals to prolong shelf life.
Frequently asked questions (FAQ)
Are these O-rings suitable for gasoline?
Nitrile (NBR) has good resistance to many fuels and oils, but for continuous exposure to strong fuels or specialized chemicals, consider fluoroelastomer (Viton) O-rings. Use NBR for typical automotive and household applications.
Do the sizes cover common metric fittings?
Yes — the 21-size assortment includes many commonly used metric inner diameters and thicknesses used in plumbing, automotive fittings, and pneumatics.
Can I use these for high-temperature engine applications?
The working temperature tops out at 120°C (248°F). For components exposed to temperatures above this range, choose a high-temperature material such as silicone or Viton.
