Generic Heater Pump Gaskets and O-Rings for hot tub spas
SKU: O-RING-GASKET
|
Overview
Sizes in o-rings and gaskets can be misleading
Our measurements may not be exact but close
The flat gaskets work best when used with the old o-ring still in place.
The flat gaskets work on both heater and pump unions.
The O-ring / gaskets are flat gaskets with half an o-ring molded on one side to hold them in place better.
The extra thick 2 gasket fills the gap on heater plumbing that is a bit off
We can mail these out via first class for a few dollars shipping
