Zodiac Large Collar with O-ring

The Zodiac R0502300 is the replacement large collar, with o-ring, for the Nature2 Fusion Soft and Nature2 Fusion inground pool water sanitizers. It is the genuine Zodiac part.

The o-ring comes with the collar, so a cracked collar or a weeping seal is fixed in one go. A light coat of silicone o-ring lubricant on the o-ring before reassembly helps it seat and seal.

This is the large collar. If you are not sure which collar your unit needs, check the Nature2 Fusion Soft or Nature2 Fusion inground parts diagram before ordering.
