Installation Procedure

1. Ensure the mating groove is clean, dry, and free from burrs or sharp edges. 2. Carefully install the O-ring into the groove, avoiding stretching or twisting beyond its elastic limit. 3. Apply a thin layer of compatible lubricant if recommended for the specific application to facilitate installation and ensure proper sealing.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overstretching the O-ring during installation, leading to premature failure and leakage.Install the O-ring without excessive stretching. If the O-ring is difficult to fit, verify the groove dimensions and consider a slightly larger cross-section O-ring if design allows.
Using incompatible lubricants or cleaning agents that degrade the silicone or stainless steel.Consult the material compatibility chart for the specific silicone compound and 316 stainless steel. Always use lubricants specifically approved for silicone and the intended operating environment.

Common Applications
