{"product_id":"discontinued-see-extended-desc-41","title":"Discontinued-See Extended Desc.","description":"\u003cp\u003eThis is the Fleck Plug (FL19691), a recessed black plug with a 0.750-inch diameter used as a port closure or finishing component within Fleck control valves. Plugs like this seal off unused passages or ports in the valve body and cover, ensuring water and brine follow only their intended paths during service and regeneration. A correctly seated plug is a small thing that quietly keeps the valve's internal hydraulics honest.\u003c\/p\u003e\u003cp\u003eThe standalone plug has been \u003cstrong\u003ediscontinued\u003c\/strong\u003e. It remains available as part of several Fleck service kits, namely \u003cstrong\u003eFL62103-02, FL62103-30, and FL62103-50\u003c\/strong\u003e. When a rebuild calls for this plug, order one of those kits to receive the current equivalent for your valve.\u003c\/p\u003e\u003ch3\u003eAbout this component\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eRecessed black plug, 0.750-inch diameter\u003c\/li\u003e\n\u003cli\u003eSeals or caps designated ports within the Fleck valve body\u003c\/li\u003e\n\u003cli\u003eGenuine Pentair Fleck part for a precise fit\u003c\/li\u003e\n\u003cli\u003eSupplied in kits FL62103-02, FL62103-30, and FL62103-50\u003c\/li\u003e\n\u003cli\u003eDiscontinued as an individual item\u003c\/li\u003e\n\u003cli\u003eHelps prevent internal cross-leaks that sap efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eSmall closure components are easy to overlook, but a missing or improperly seated plug can create internal cross-leaks that sap regeneration efficiency and let untreated water bypass the media bed. Because these leaks are internal, they often go undiagnosed for a long time, showing up only as gradually declining softness or higher salt consumption that the homeowner attributes to other causes.\u003c\/p\u003e\u003cp\u003eDuring a valve rebuild, inspect all plugs and caps for cracks, distortion, or a poor seal, and replace any that show wear. A new plug is inexpensive insurance against an annoying, hard-to-trace performance loss. Since this part is no longer offered separately, use the referenced FL62103 kits to source it along with the other seals and components those kits provide. As always, place the valve in bypass and relieve pressure before opening the control head for service, and apply a light film of silicone lubricant to the plug's O-ring during reassembly for a clean, watertight fit. Keeping a few of these inexpensive plugs in your service kit means you are never held up by a single missing closure when a rebuild is otherwise ready to go back together. Taking the time to verify every port is correctly capped before returning the valve to service is a small discipline that pays off in consistent softening and predictable salt usage for years afterward.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":45668807737397,"sku":"FL19691","price":1.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/4950\/2261\/files\/fl19691.jpg?v=1782533993","url":"https:\/\/watersoftenerplus.com\/nl-eu\/products\/discontinued-see-extended-desc-41","provider":"Water Softener Plus","version":"1.0","type":"link"}
