How to use

Select an O-ring of matching inner diameter and cross-section to the original seal. Inspect the groove and mating surfaces for debris or damage and clean before installation. Lightly lubricate the O-ring with a compatible lubricant if required to ease fitting and reduce abrasion. Fit the O-ring into the groove without twisting, then reassemble the joint and tighten according to the component’s specifications to achieve proper sealing without overstressing the ring.

Usage recommendations

Keep spare O-rings stored in a dry, cool place away from direct sunlight and ozone sources. When choosing a replacement, verify chemical compatibility and temperature limits for the application; for critical systems select materials rated for the specific fluid or gas and operating temperature.
