Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using an O-ring of incorrect size, leading to leaks or improper sealing.Always verify the required O-ring dimensions (ID, OD, cross-section) against the groove specifications before installation.
Overtightening fasteners, which can compress the O-ring excessively and cause premature failure.Follow torque specifications for fasteners to ensure the O-ring is compressed to its optimal sealing range.
Installing a damaged or degraded O-ring, compromising the seal integrity.Inspect the O-ring for nicks, cuts, or signs of hardening/cracking before installation.
