A prominent fitting manufacturer was experiencing high warranty claims due to reported leaks once the product was in use in the field.
The fitting manufacturer was installing o-rings onto their fittings and placing fittings onto shelves for two to three weeks before final assembly. After this period of time, the o-rings had visible cracks on their surface due to ozone attack.
Proper packaging, storage, and the utilization of lubricants are all techniques that would prevent an ozone attack from occuring. If it is necessary to pre-assemble o-rings onto hardware and proper storage processes cannot be followed, Parker O-ring Division offers many ozone resistant compounds.
