One face is flat, the other carries a molded raised O-ring rib that compresses into the union groove for a leak-tight seal without thread sealant or Teflon tape. Replace it any time you break a 2 inch union, swap a heater element, or chase a slow drip at the pump suction or discharge.\u003c\/p\u003e\n\n  \u003csection class=\"wwunion-spec-section\"\u003e\n    \u003cdiv class=\"wwunion-spec-heading\"\u003eSpecifications\u003c\/div\u003e\n    \u003ctable class=\"wwunion-spec-table\"\u003e\n      \u003ctbody\u003e\n        \u003ctr\u003e\n\u003cth\u003eManufacturer\u003c\/th\u003e\n\u003ctd\u003eWaterway\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eModel \/ MPN\u003c\/th\u003e\n\u003ctd\u003e711-4030B\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSKU\u003c\/th\u003e\n\u003ctd\u003ePST-WW7114030B\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFits Union Size\u003c\/th\u003e\n\u003ctd\u003e2 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOuter Diameter\u003c\/th\u003e\n\u003ctd\u003e2-15\/16 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInner Diameter\u003c\/th\u003e\n\u003ctd\u003e2-1\/8 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFlat Section Thickness\u003c\/th\u003e\n\u003ctd\u003e3\/32 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTotal Thickness with Rib\u003c\/th\u003e\n\u003ctd\u003e3\/16 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProfile\u003c\/th\u003e\n\u003ctd\u003eFlat one side, ribbed raised O-ring opposite side\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eChemical resistant elastomer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCommon Use\u003c\/th\u003e\n\u003ctd\u003eHeater unions, pump suction and discharge unions, flow switch unions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCross Reference\u003c\/th\u003e\n\u003ctd\u003e711-4030, 6000-287, 610874\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCompatible Brands\u003c\/th\u003e\n\u003ctd\u003eWaterway, Gecko, Hydro-Quip, Aeware, United, Balboa heater assemblies with 2 inch unions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSold As\u003c\/th\u003e\n\u003ctd\u003eEach (one gasket)\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003c\/tbody\u003e\n    \u003c\/table\u003e\n  \u003c\/section\u003e\n\n  \n  \u003csection class=\"wwunion-faq\"\u003e\n    \u003cdiv class=\"wwunion-spec-heading\"\u003eGood to Know\u003c\/div\u003e\n    \n    \u003cdiv class=\"wwunion-faq-item\"\u003e\n      \u003cp class=\"wwunion-faq-q\"\u003eWhich side of the gasket faces the union nut?\u003c\/p\u003e\n      \u003cp class=\"wwunion-faq-a\"\u003eSeat the gasket so the \u003cstrong\u003eraised ribbed O-ring side\u003c\/strong\u003e faces the union groove on the heater or pump body, and the flat side rides against the union tailpiece.
