It has a low opening pressure of 1 psi. This check valve is suitable for clean liquids such as water or for gas. Since it cannot be disassembled for cleaning, we do not recommend it for beverage applications. The internal components are made from stainless steel. Compatible with EVABarrier 8 mm OD Tubing (\u003ca href=\"https:\/\/northtexashomebrew.com\/product\/evabarrier-double-wall-draft-tubing-4mm-5-32-id-x-8mm-5-16-od\/\"\u003eD1717\u003c\/a\u003e, D1718).\n\nDuotight fittings are high-quality push-in fittings that seal tight and offer superior sealing capacity due to the double O-ring sealing design.\n\nHigh Performance Double O-Ring Design:\n\nThe secret to Duotight’s superior sealing performance comes from the fact that they use not one, but two high-quality EPDM O-rings.  The double O-ring means they have literally twice the sealing surface when compared with other push-in fittings.  This makes them more reliable and significantly reduces the chance of leakage.\n\nThe double O-ring system also means that tubing can be bent at a much tighter radius without causing leaking issues, which can be an issue with other fittings.  This combination of factors makes Duotight the most reliable push-in fittings on the market.\n\nEPDM offers excellent chemical resistance for a longer life span. When compared with silicone and vinyl, EPDM has much better gas transmission rates, better wear resistance, and is BPA-free.\n\nNo Clamps Necessary!\n\nWe recommend cutting your tubing straight, not on an angle, to ensure the line forms a complete seal. To remove the fitting simply push in the collet and the hose can be removed.\n\nFeatures:\n\nInsert tubing and firmly push to connect\n\nEasily release tubing by pushing in the collet\n\nSuitable for both gas \u0026amp; water applications\n\nMade from food-grade acetal plastic\n\nDouble O-rings made from highly chemical resistant EPDM\n\nLocking teeth made from stainless steel\n\nPressure rated to 150 psi\n\nTemperature rated to 212°F (100°C)","brand":"Kegland","offers":[{"title":"Default Title","offer_id":47280929210556,"sku":"duo110","price":4.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0790\/7370\/6172\/files\/duocheckvalve.jpg?v=1786816898","url":"https:\/\/nthbs.com\/products\/duotight-push-in-fitting-check-valve-8mm-5-16","provider":"North Texas Homebrew Supply","version":"1.0","type":"link"}
