{"product_id":"guest-3-8x1-4-union-stem-x-tube","title":"Guest 3\/8x1\/4 Union, Stem x Tube","description":"\u003cp\u003eThe John Guest 3\/8\" Stem x 1\/4\" Tube Union from Reliance Worldwide Corporation links a 3\/8\" stem to a 1\/4\" tube port, giving you a direct plug-in connection on one side and a standard push-fit tube grip on the other. It is a handy fitting for compact reverse osmosis and water filtration builds that need both a component connection and a tube run handled in a single piece.\u003c\/p\u003e\u003cp\u003eThe 3\/8\" stem end is meant to push directly into another John Guest fitting, while the 1\/4\" tube end accepts flexible tubing. This dual nature lets you connect a component and a tube run at once, cutting down on the number of joints in tight cabinet installations. Fewer joints means fewer potential leak points and a cleaner, more serviceable layout overall.\u003c\/p\u003e\u003ch3\u003ePlug-In Convenience\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eConnection: Tube x Tube, 3\/8\" stem to 1\/4\" tube\u003c\/li\u003e\n\u003cli\u003eStem union mates directly with John Guest ports\u003c\/li\u003e\n\u003cli\u003ePolypropylene body resists corrosion and scale\u003c\/li\u003e\n\u003cli\u003ePush-fit tube side seats in seconds without tools\u003c\/li\u003e\n\u003cli\u003eFully demountable for easy servicing\u003c\/li\u003e\n\u003cli\u003eReduces junctions in space-limited installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eTo install, push the 3\/8\" stem fully into the receiving fitting's collet until it bottoms out, then cut your 1\/4\" tube square and free of burrs and insert it into the tube port until it seats. The internal O-rings seal both connections automatically, and a gentle tug confirms the tube grip. The corrosion-resistant polypropylene construction holds up to years of contact with treated water without scaling or rusting. When it is time to service the system, depress the collets to release the stem and tube cleanly and undamaged, then reassemble once the work is done. For reliable size and connection transitions in residential water treatment plumbing, this John Guest stem union is a smart, space-saving pick.\u003c\/p\u003e\u003cp\u003eAs part of the wider John Guest range, this stem union works hand in hand with the elbows, tees, valves, and connectors that use the same collet system, so a complete layout can be assembled from interchangeable parts. The stem design in particular shines in crowded cabinets, where plugging a component straight into a mating fitting saves both space and an extra junction that could otherwise leak.\u003c\/p\u003e","brand":"Reliance Worldwide Corporation","offers":[{"title":"Default Title","offer_id":45668821794869,"sku":"JG0302SU","price":14.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/4950\/2261\/files\/jg0302su.jpg?v=1782534545","url":"https:\/\/watersoftenerplus.com\/es-eu\/products\/guest-3-8x1-4-union-stem-x-tube","provider":"Water Softener Plus","version":"1.0","type":"link"}
