Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-stretching the O-ring during installation, leading to premature failure and leakage.Install the O-ring without excessive tension. If the O-ring is difficult to fit, consider a slightly larger size or a different cross-section.
Contaminating the O-ring or groove with lubricants or cleaning agents incompatible with silicone or 304 stainless steel.Use only approved lubricants and cleaning agents specified for silicone and stainless steel applications. Ensure all surfaces are thoroughly dried before assembly.
