It creates a pressure-tight seal between the pump body and volute assembly. The seal prevents leaks at one of the highest-stress joints in the pump. Proper sealing is critical for maintaining flow efficiency and pump prime. This part restores the original factory seal between housing components.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eWhy This Part Matters\u003c\/strong\u003e\u003cbr\u003e A failed volute O-Ring often causes visible leaks and air infiltration. Even small leaks can reduce pump performance and increase noise. Continued operation with a compromised seal can lead to motor damage or overheating. Replacing the O-Ring restores hydraulic integrity without replacing the entire pump. Correct sizing ensures uniform compression and long-term reliability.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eKey Features and Specifications\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eWaterway Plastics manufacturer part number 805-0261\u003c\/li\u003e \u003cli\u003eO-Ring size designation #261\u003c\/li\u003e \u003cli\u003eDesigned for pump volute sealing\u003c\/li\u003e \u003cli\u003eUsed on select Waterway pump models\u003c\/li\u003e \u003cli\u003eMaintains pressure between pump housing components\u003c\/li\u003e \u003cli\u003eRound profile O-Ring design\u003c\/li\u003e \u003cli\u003eSingle replacement seal\u003c\/li\u003e \u003cli\u003eService replacement component\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eInstallation and Fitment Guidance\u003c\/strong\u003e\u003cbr\u003e Disassemble the pump according to manufacturer procedures. Inspect the volute groove for debris or damage before installation. Light lubrication may be used to assist proper seating. Tighten fasteners evenly to avoid housing distortion. Confirm by manufacturer part number before ordering.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eAbout the Waterway Plastics Brand\u003c\/strong\u003e\u003cbr\u003e Waterway Plastics designs pump systems trusted throughout the pool and spa industry. Their volutes and sealing systems are engineered for precise alignment and pressure control. OEM manufacturers frequently specify Waterway pumps for new installations. Replacement parts are built to match original tolerances. This consistency simplifies service work. Waterway continues to set industry standards for reliability.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eCommon Service Context\u003c\/strong\u003e\u003cbr\u003e This O-Ring is commonly replaced during pump rebuilds or seal kit installations. Technicians encounter it when addressing leaks between pump sections. It is also replaced during motor swaps or housing separation. Water around the volute seam is a typical indicator.\u003c\/p\u003e","brand":"Waterway Plastics","offers":[{"title":"Default Title","offer_id":52008420311314,"sku":"805-0261","price":3.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/2279\/1186\/files\/WWP8050261_0.jpg?v=1770399520","url":"https:\/\/www.aquaterrabackyard.com\/products\/waterway-plastics-805-0261-o-ring-volute-261","provider":"Aqua Terra Backyard","version":"1.0","type":"link"}
