If you are servicing a Pentair pump and need to restore a proper seal at the suction port, this is the correct OEM replacement component.\u003c\/p\u003e\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\u003cp\u003eThe suction gasket seals the connection at the pump's suction inlet, preventing air from entering the hydraulic circuit and maintaining prime. A compromised or deteriorated suction gasket allows air infiltration, which reduces pump efficiency and can cause the pump to lose prime entirely. Match the part number C20-123-50 to the number stamped or molded on your existing gasket before ordering.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0px; border: 1px solid rgb(204, 204, 204); height: 97.9545px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color: rgb(248, 249, 250); height: 19.5909px;\"\u003e\n\u003ctd style=\"border: 1px solid rgb(204, 204, 204); padding: 10px; height: 19.5909px;\"\u003e\u003cstrong\u003ePentair Part Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid rgb(204, 204, 204); padding: 10px; height: 19.5909px;\"\u003eC20-123-50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5909px;\"\u003e\n\u003ctd style=\"border: 1px solid rgb(204, 204, 204); padding: 10px; height: 19.5909px;\"\u003e\u003cstrong\u003ePart Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid rgb(204, 204, 204); padding: 10px; height: 19.5909px;\"\u003eSuction Gasket\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: rgb(248, 249, 250); height: 19.5909px;\"\u003e\n\u003ctd style=\"border: 1px solid rgb(204, 204, 204); padding: 10px; height: 19.5909px;\"\u003e\u003cstrong\u003eApplication\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid rgb(204, 204, 204); padding: 10px; height: 19.5909px;\"\u003ePool and Spa Pump\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5909px;\"\u003e\n\u003ctd style=\"border: 1px solid rgb(204, 204, 204); padding: 10px; height: 19.5909px;\"\u003e\u003cstrong\u003eQuantity Included\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid rgb(204, 204, 204); padding: 10px; height: 19.5909px;\"\u003eEach\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5909px;\"\u003e\n\u003ctd style=\"border: 1px solid rgb(204, 204, 204); padding: 10px; height: 19.5909px;\"\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid rgb(204, 204, 204); padding: 10px; height: 19.5909px;\"\u003e4.7\" x 4.7\" square\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003ePro Tip\u003c\/h3\u003e\n\u003cp\u003eBefore ordering, verify the part number C20-123-50 against the number stamped or molded on your existing suction gasket.
