It is the genuine Pentair part, molded in plastic.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere it sits\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe spacer belongs to the bulkhead assembly at the tank penetration. It sits on the outside and sets the standoff, which is what lets the assembly pull up square and load its seals evenly all the way around. Left out or fitted with the wrong size, the joint clamps unevenly and weeps under pressure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhile you have it apart\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA spacer usually only comes out when a bulkhead is being rebuilt. Gaskets that have been compressed for years rarely reseal after being disturbed, so plan on replacing the seals in the joint at the same time rather than finding out at start up.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48633769132244,"sku":"PAC-051-2811","price":22.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_1a10574d-ac38-402d-b7b5-b1d0ea4beab1.png?v=1788815029","url":"https:\/\/www.activepoolsupply.com\/products\/external-spacer","provider":"Active Pool Supply","version":"1.0","type":"link"}
