The assembly combines an ABS body, neoprene valve seat, a stainless steel spring and an integrated sight glass to help operators see flow direction and backwash performance. It replaces worn or damaged couplings and restores precise, leak-resistant valve operation without modifying existing plumbing when using 1.5\" female threaded connections.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this coupling improve backwash performance?\u003c\/h3\u003e\n\u003cp\u003eThe SP0710XR50 coupling works with the Vari-Flo six-position valve to channel water accurately for filtration, backwash, rinse and waste cycles.

Pool technicians, maintenance teams, and DIY owners who service Hayward Pro-Series or other compatible Vari-Flo valve systems will benefit most. Choose the SP0710XR50 when you need a dependable 1.5\" FIP coupling with a long-lasting valve seat, simple installation, and features that cut down routine maintenance. If your filter uses different thread sizes or a non-Vari-Flo valve, confirm compatibility before ordering to ensure a correct fit.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is this coupling compatible with 1.5\" FIP plumbing?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — the SP0710XR50 is designed for 1.5\" female iron pipe (FIP) threaded connections.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does the part include a sight glass and self-cleaning feature?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — it has a built-in sight glass and an automatic self-cleaning design to reduce clogging.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":56801461928276,"sku":"B002EL3Z64","price":223.42,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1063\/2652\/4244\/files\/hayward-sp0710xr50-front-coupling.jpg?v=1786742380","url":"https:\/\/gardenluxe.co.uk\/products\/hayward-vari-flo-backwash-valve-coupling-sp0710xr50-1-5-fip-pro-series-self-cleaning-with-sight-glass","provider":"Gardenluxe Uk","version":"1.0","type":"link"}
