Hayward Handle and Piston Assembly | SPX0410BA Panama Jack Onyx Collection enhancing the overall visual appealWhat This Part Is Used For The SPX0410BA handle and piston assembly is used in compatible Hayward push pull or slide valve systems to control backwash and filter functions. It connects the external handle to the internal piston for water direction control. Why This Part Matters A worn piston or damaged handle can cause internal bypass or water leakage. That may reduce filtration efficiency or allow water to discharge incorrectly during backwash.
