Description
Coast Spas o-ring for 2-inch union fittings used where pumps, heaters and main lines join. It sits between the union faces to stop water from escaping when the nut is tightened. Made of EPDM, it resists chlorine, bromine, salt and hot water. Many other spa brands with 2-inch unions in the Waterway or Balboa pattern can use it as well. Replace it whenever you see leaks or a worn seal. Sold individually.
