This is the large rubber O-ring (item 3 in the PB4-50 exploded diagram) that seals the volute (pump body) to the bracket adaptor plate on the Polaris PB4-50 booster pump. A worn or cracked O-ring causes water to leak from the joint between the volute and the bracket adaptor. Replacing this O-ring restores a watertight seal.\u003c\/p\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePolaris PB4-50 Booster Pump — 2011 to current (new style)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eProduct Details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: Polaris \/ Zodiac\u003c\/li\u003e\n\u003cli\u003ePart number \/ SKU: WS0137300\u003c\/li\u003e\n\u003cli\u003ePosition: item 3 in PB4-50 exploded diagram (volute \/ bracket adaptor O-ring)\u003c\/li\u003e\n\u003cli\u003eGenuine Polaris spare part\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003ch3\u003eHow do I know if this O-ring needs replacing?\u003c\/h3\u003e\n\u003cp\u003eIf water is leaking from the joint between the pump volute (the front pump body) and the bracket adaptor plate, this O-ring is the most likely cause. Turn off the pump and relieve system pressure before inspecting. Remove the volute bolts, separate the volute from the bracket adaptor, and inspect the O-ring for cracks, flattening, or deformation. Replace if any damage or deterioration is visible.\u003c\/p\u003e\n\n\u003ch3\u003eDoes this suit the older PB4-60 or pre-2011 PB4-50?\u003c\/h3\u003e\n\u003cp\u003ePart WS0137300 suits the \u003cstrong\u003ePB4-50 from 2011 to current\u003c\/strong\u003e (new style). Pre-2011 PB4-50 and PB4-60 models may use a different O-ring. If you are unsure of your pump’s manufacture date, check the label on the pump body or contact us with your pump’s serial number before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eShould I lubricate the O-ring when fitting it?\u003c\/h3\u003e\n\u003cp\u003eYes — apply a small amount of silicone-based O-ring lubricant (not petroleum-based grease) to the O-ring before fitting. This helps the O-ring seat correctly and extends its service life.\u003c\/p\u003e","brand":"Zodiac","offers":[{"title":"Default Title","offer_id":45287857062163,"sku":"WS0137300","price":10.35,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/0591\/1827\/products\/Polaris-Oring-Bracket-Adaptor_7364765a-b901-4e7e-92b2-c57484131ca6.jpg?v=1684891911","url":"https:\/\/poolshop.com.au\/products\/polaris-pb4-50-booster-pump-bracket-adaptor-oring-ws0137300","provider":"Pool Shop Australia","version":"1.0","type":"link"}
