It is the genuine Pentair part and belongs to the heater burner system group.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen you need it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe combustion chamber has to seal on reassembly. Any job that opens it up, igniter work, burner tray service, an inspection after a shutdown, disturbs the seals, and a seal that has been compressed once has usually taken a permanent set. Refitting an old one is the common reason a chamber will not close up tight again.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis kit is listed for the MasterTemp 125. The larger MasterTemp models use their own seal parts, so check the model plate on the heater rather than going by the family name.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48629300789460,"sku":"PUR-151-3844","price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/pentair_474952.jpg?v=1788762109","url":"https:\/\/www.activepoolsupply.com\/products\/pentair-474952-combustion-chamber-o-ring-kit","provider":"Active Pool Supply","version":"1.0","type":"link"}
