Genuine Pentair. I used this to fix a leak on my spa heater where the PVC pipe connects.

If you're looking for the O-ring to replace for a Pentair Mastertemp pool heater for either the in/outlet this doesn't fit. it is too small and isn't a match.

This fit perfectly on my old pump... about four months and not a single drop of water has leaked.
