{"product_id":"fleck-o-ring-019-2900","title":"Fleck O-Ring, -019, 2900","description":"\u003cp\u003eThis is a genuine Fleck -019 O-ring made for the 2900 control valve, supplied by Pentair. Designated by its AS568 dash-number size (-019), this small elastomer seal creates a watertight barrier between mating parts inside the valve body, preventing leaks and internal bypass at one of the valve's critical joints. Despite its modest size and cost, an O-ring like this is fundamental to keeping a control valve sealed and operating at full pressure.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOEM Fleck -019 size O-ring for the 2900 valve\u003c\/li\u003e\n\u003cli\u003eForms a reliable seal between internal valve surfaces\u003c\/li\u003e\n\u003cli\u003eHelps prevent leaks and internal bypass\u003c\/li\u003e\n\u003cli\u003eResilient elastomer rated for potable-water service\u003c\/li\u003e\n\u003cli\u003eExact-fit replacement, no trimming required\u003c\/li\u003e\n\u003cli\u003eStandardized dash size for accurate, repeatable fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThe Fleck 2900 is a high-flow control valve used on larger residential and light-commercial softeners and filters, where dependable sealing is essential to maintain flow, pressure, and accurate cycle behavior. Because the 2900 handles substantial volumes of water, even a minor leak at an internal joint can develop into a noticeable drip or a loss of efficiency over time.\u003c\/p\u003e\u003cp\u003eOver years of service, O-rings gradually lose elasticity, harden, or take a compression set, and a tired seal is one of the most common sources of weeping leaks and erratic valve performance. Heat, chlorine, and mechanical compression all contribute to this aging. Refreshing O-rings is inexpensive insurance during any valve rebuild, and many technicians replace the full O-ring complement whenever they have a valve open rather than risk a return visit. Because this part is factory-correct and sized specifically for the 2900 in the -019 dimension, it seats properly and restores the original seal without guesswork or improvisation. Installing a fresh genuine O-ring returns the valve to leak-free, reliable operation and helps protect the surrounding equipment and finished space from water damage.\u003c\/p\u003e\u003cp\u003eFor installers, carrying a selection of common Fleck O-ring sizes turns most leak repairs into a same-visit fix. The -019 is one of several seals worth keeping on hand for 2900 service, since a high-flow valve often has multiple O-rings that age at a similar rate. Proactively renewing the full seal set during any major service keeps a large softener or filter operating quietly and leak-free, protecting both the equipment and the space around it from water damage.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":45668803018805,"sku":"FL14812","price":6.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/4950\/2261\/files\/fl14812.jpg?v=1782533783","url":"https:\/\/watersoftenerplus.com\/ja-as\/products\/fleck-o-ring-019-2900","provider":"Water Softener Plus","version":"1.0","type":"link"}
