Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening fasteners, causing excessive compression and premature failure.Adhere to recommended torque specifications for fasteners to avoid over-compression of the O-ring.
Using incompatible lubricants that degrade the Viton material.Only use lubricants explicitly rated for compatibility with Viton to prevent material degradation and sealing failure.

Common Applications

  • High-temperature sealing in engines and exhaust systems
  • Chemical processing equipment seals
  • Aerospace hydraulic and fuel systems

⚠️ Engineering Warnings

  • Avoid exposure to certain high-concentration ketones and esters, which can degrade Viton.
  • Ensure proper material compatibility with all fluids and gases in the operating environment.
