It is the genuine Speck part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere it sits\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe casing o-ring seals the split in the pump housing. That joint has to hold on both sides of the impeller, against suction on the way in and pressure on the way out, so a ring that has hardened or taken a set shows up as air pulled into the system or as water weeping from the seam. Neither symptom improves on its own.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOrdering and fitting\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eCheck the measurement, 215 mm by 6 mm, against the ring you have out. The source lists this same part under both the Model 433 and the Model E91 pump breakdowns, so verify the number against your own pump rather than going by model name alone. Clean the groove, dress the new ring with a silicone based lubricant, and draw the casing bolts down evenly.\u003c\/p\u003e","brand":"Speck Pumps","offers":[{"title":"Default Title","offer_id":48629099299028,"sku":"SPK-101-2697","price":15.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_2db37c38-2740-407f-9e05-5ace19bc65ae.jpg?v=1788759672","url":"https:\/\/www.activepoolsupply.com\/products\/o-ring-for-casing-model-433","provider":"Active Pool Supply","version":"1.0","type":"link"}
