{"product_id":"guest-tube-support-3-8","title":"Guest Tube Support, 3\/8","description":"\u003cp\u003eThe John Guest 3\/8\" Tube Support from Reliance Worldwide Corporation is a small insert that reinforces the end of soft or flexible tubing, helping it hold its round shape inside a push-fit fitting for a more reliable seal. It is an easy, inexpensive upgrade for water filtration and reverse osmosis lines where a dependable connection is essential.\u003c\/p\u003e\u003cp\u003eFlexible tubing can deform slightly under the grip of a collet or over time under pressure, and even a small loss of roundness can compromise the seal between the O-ring and the tube wall. A tube support, sometimes called a tube insert or stiffener, slides into the tube end to keep the bore open and the wall fully round. This ensures the O-ring seats evenly all the way around, which is the key to a leak-free push-fit joint.\u003c\/p\u003e\u003ch3\u003eBenefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eReinforces the tube end against deformation\u003c\/li\u003e\n\u003cli\u003ePromotes a consistent, leak-free O-ring seal\u003c\/li\u003e\n\u003cli\u003eMade from durable, corrosion-resistant polypropylene\u003c\/li\u003e\n\u003cli\u003eSized for 3\/8\" John Guest tubing and fittings\u003c\/li\u003e\n\u003cli\u003eInserts by hand with no tools required\u003c\/li\u003e\n\u003cli\u003eEspecially helpful with softer tubing and pressure cycling\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eTo use, simply push the tube support into the end of your 3\/8\" tubing before inserting the tube into a John Guest fitting. The support is particularly valuable with softer tubing materials and in systems that experience repeated pressure cycling, where an unsupported tube end is most likely to deform over time. Once the support is in place, complete the connection as usual by pushing the tube fully into the fitting's collet until it bottoms out, then confirm the grip with a gentle tug. Because the support resists corrosion and scale, it performs reliably throughout the life of the tubing. For added assurance against leaks in residential water treatment plumbing, this John Guest tube support is an inexpensive, worthwhile addition to any build.\u003c\/p\u003e\u003cp\u003eWhile not every installation strictly requires a tube support, adding one is cheap insurance on the connections that matter most, particularly those that will sit under constant pressure or are difficult to reach for future service. Many experienced installers fit supports on all soft-tube connections as a matter of routine, treating the small extra step as worthwhile assurance against the slow leaks that deformed tube ends can cause.\u003c\/p\u003e","brand":"Reliance Worldwide Corporation","offers":[{"title":"Default Title","offer_id":45668822482997,"sku":"JG03TS","price":0.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/4950\/2261\/files\/jg03ts.jpg?v=1782534575","url":"https:\/\/watersoftenerplus.com\/pl-eu\/products\/guest-tube-support-3-8","provider":"Water Softener Plus","version":"1.0","type":"link"}
