This is a Standard 2" Heater or Pump Union Gasket featuring a 2 1/2" Lip Center to Center. Outer diameter measures 2 7/8" across, inner diameter is approximately 2 3/16", and the lip designed to fit into the union measures 2 1/2" center to center. Compatible with most unions, though exceptions exist so please verify measurements. If the ridge doesn't fit your specific union, simply trim it off to use as a flat gasket. This component creates a seal between your hot tub heater or pump union and the heater or pump assembly.
