{"product_id":"1-2-brass-tube-support","title":"1\/2\" Brass Tube Support","description":"\u003cp\u003eThis 1\/2-inch brass tube support is a metal insert (Midland Metal Mfg, also cross-referenced as Fleck part FL15415) that reinforces the inside of 1\/2\" flexible or soft tubing at a compression connection. Slipped into the tube end, the support holds the tubing round and rigid so a compression nut and ferrule can grip evenly and form a leak-tight seal. It is a small but important component for making dependable joints in soft-walled tubing.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1\/2\" brass tube support insert\u003c\/li\u003e\n\u003cli\u003eReinforces tubing at compression fittings\u003c\/li\u003e\n\u003cli\u003ePrevents tube collapse under nut compression\u003c\/li\u003e\n\u003cli\u003eCorrosion-resistant brass construction\u003c\/li\u003e\n\u003cli\u003eCross-referenced to Fleck part FL15415\u003c\/li\u003e\n\u003cli\u003eHelps create reliable, leak-free brine-line joints\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eSoft and semi-rigid tubing tends to deform or collapse when a compression nut is tightened directly onto it, which leads to weak, leak-prone joints that may seep or pull apart under pressure. A tube support solves this by providing internal backing, ensuring the ferrule bites against a firm wall and the connection holds pressure reliably over time. Without it, even a properly torqued fitting can fail as the tubing slowly cold-flows under the clamping force.\u003c\/p\u003e\u003cp\u003eBrass is the material of choice here for its corrosion resistance and its long-standing compatibility with potable-water plumbing, making it well suited to the wet, sometimes salty conditions around water-treatment equipment. In water-treatment installations, brass tube supports are commonly used on brine lines and other small-diameter tubing runs around softeners and filters, where a secure connection is essential to consistent operation.\u003c\/p\u003e\u003cp\u003eUsing the correct 1\/2\" support is a small step that makes a meaningful difference in connection integrity. It helps installers and homeowners avoid the slow drips and air leaks that can undermine brine draw, reduce softening efficiency, or cause water damage. Keeping a few on hand ensures every compression joint in a 1\/2\" tubing run can be made up correctly the first time.\u003c\/p\u003e\u003cp\u003eFor technicians, stocking a few brass tube supports in common sizes is cheap insurance against the slow leaks that can develop weeks after an installation when soft tubing finally yields under a compression nut. Using a support every time a compression fitting is made up on soft 1\/2-inch tubing ensures each joint holds the first time, sparing both installer and homeowner the nuisance of a callback for a connection that should have been solid from the start.\u003c\/p\u003e","brand":"Midland Metal Mfg","offers":[{"title":"Default Title","offer_id":45668804427829,"sku":"FL15415","price":1.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/4950\/2261\/files\/fl15415.jpg?v=1782533861","url":"https:\/\/watersoftenerplus.com\/th-as\/products\/1-2-brass-tube-support","provider":"Water Softener Plus","version":"1.0","type":"link"}
