This is a genuine Starway replacement Viton (FKM) O-ring, sized 6.07 mm inner diameter \u00d7 1.78 mm cross-section, designed to maintain a leak-free seal within the Starway Automatic Backwash Valve. It provides a reliable static seal that keeps the valve operating correctly during automated sand-filter backwash cycles.<\/p>\n
This O-ring is a genuine Starway spare part for the Starway motorised 5-way Automatic Backwash Valve used in pool sand filtration systems. Always verify your valve model and the part reference (Type 2027) against your valve’s parts list before ordering, as multiple O-ring sizes are used within the valve assembly.<\/p>\n
Viton (FKM) fluorine rubber offers outstanding resistance to pool chemicals, chlorine by-products, and elevated temperatures \u2014 far outperforming standard NBR rubber in harsh pool environments. With a working temperature range up to +200 \u00b0C and a Shore A hardness of approximately 80, this O-ring holds its shape and sealing force over extended service life, reducing the risk of costly valve leaks or premature failure.<\/p>\n
Before fitting, clean the O-ring groove thoroughly and remove all traces of the old seal. Apply a thin coat of silicone grease to the new O-ring to ease installation and prevent rolling. Hand-tighten only \u2014 no tools should contact the O-ring directly. If you are unsure about disassembling the backwash valve, consult a qualified pool technician.<\/p>","protected":false},"excerpt":{"rendered":"
