PRODUCT CHANGE — AccuLock™ S Conventional Liner Gas Diffusers — O-Ring Color Change to Gray

All AccuLock S conventional liner gas diffusers began shipping with a gray o-ring instead of a black o-ring on February 22, 2023. The gray o-ring makes it easier to tell the difference between an AccuLock S dual-locked liner gas diffuser and an AccuLock S conventional liner gas diffuser.

For reference, the AccuLock gas diffuser part numbers listed below will be assembled with a gray o-ring:
