{"product_id":"o-ring-for-ssi-uv-quartz-sleeve","title":"O-Ring - for Wrekin SSi UV Quartz Sleeve 30x4mm EPDM - Master","description":"\u003cp\u003eThis 30x4mm EPDM O-ring is the replacement seal for Wrekin SSi UV quartz sleeves, fitting the 15WQS, 30WQS and 75WQS models. WrekinWater stocks it as the correct-size fix for a sleeve joint that has started to weep, rather than asking you to guess at a generic rubber seal from a hardware shop. EPDM is a durable rubber compound well suited to the chlorinated, warm conditions inside a UV chamber.\u003c\/p\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eO-ring seal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e30 x 4mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eEPDM rubber\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatible systems\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eWrekin SSi 15WQS, 30WQS and 75WQS UV quartz sleeves\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePack size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSingle O-ring (SKU 10022026)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eSigns this seal needs replacing\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eWater is weeping or dripping from the quartz sleeve joint.\u003c\/li\u003e\n\u003cli\u003eThe old O-ring feels hard, flattened, or cracked when you remove the sleeve.\u003c\/li\u003e\n\u003cli\u003eThe joint keeps leaking even after you've refitted and retightened the housing.\u003c\/li\u003e\n\u003cli\u003eThe rubber has taken on a permanent groove from sitting compressed for a long time.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThis EPDM O-ring keeps the joint between the quartz sleeve and its housing watertight on Wrekin SSi 15WQS, 30WQS and 75WQS systems. EPDM is chosen because it copes reasonably well with the chlorine and warmth found inside a working UV chamber, but no rubber lasts forever under those conditions — over time it hardens and loses its ability to compress and seal. Left in place, a perished O-ring will eventually let water weep past the sleeve.\u003c\/p\u003e\n\u003cp\u003eWrekinWater has been fitting and supplying parts for SSi UV systems as part of a wider stock of major water treatment brands for over 15 years, so we hold the correct EPDM size rather than a generic substitute. Getting the exact 30x4mm dimension matters here — too loose a fit and the joint will never seal properly, however hard you tighten it.\u003c\/p\u003e\n\u003ch3\u003eHow to replace it\u003c\/h3\u003e\u003col\u003e\n\u003cli\u003eIsolate the water supply to the UV unit and depressurise the line.\u003c\/li\u003e\n\u003cli\u003eUndo the sleeve retaining nut or union and withdraw the quartz sleeve from the housing.\u003c\/li\u003e\n\u003cli\u003eRemove the old O-ring and wipe away any scale from the sleeve and the housing seat.\u003c\/li\u003e\n\u003cli\u003eLightly grease the new 30x4mm EPDM O-ring with food-safe silicone grease before fitting.\u003c\/li\u003e\n\u003cli\u003eRefit the sleeve and union, restore the water supply, and check the joint for leaks.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Wrekin Water","offers":[{"title":"Default Title","offer_id":53562654982473,"sku":"10022026","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0896\/0235\/9625\/files\/WonderORing.jpg?v=1749643561","url":"https:\/\/wrekinwatertreatment.co.uk\/products\/o-ring-for-ssi-uv-quartz-sleeve","provider":"WrekinWater","version":"1.0","type":"link"}
