This carbon steel tank is pre-charged at 12 psi, tank volume is 15.0 gallons and features a durable expansion membrane that prevents contact of the water with the air in the tank. This rugged butyl diaphragm minimizes loss of the air change and ensures long and trouble-free life for the system. This tank is made of carbon steel with epoxy finish, mounts to supply piping, 3\/4 inch MNPT system connection and a 0.302-32 inch charging valve connection (standard tire valve) to facilitate on-site charging of the tank to meet system requirements. The maximum working pressure is 75 psi (5.3 bar).\u003c\/p\u003e\n\n\u003cstrong\u003eFeatures\u003c\/strong\u003e\n\u003cul\u003e\n \u003cli\u003ePrecharged to 12 psi\u003c\/li\u003e\n \u003cli\u003eRugged flexible butyl diaphragm\u003c\/li\u003e\n \u003cli\u003eInline and free standing models\u003c\/li\u003e\n \u003cli\u003eSteel construction\u003c\/li\u003e\n \u003c\/ul\u003e\n\u003ctable\u003e\n \u003cthead\u003e\n \u003ctr\u003e\n \u003cth colspan=\"2\" style=\"text-align: left;\"\u003eSpecifications\u003c\/th\u003e\n \u003c\/tr\u003e\n \u003c\/thead\u003e\n \u003ctbody\u003e\n\u003ctr\u003e\n \u003ctd\u003eAir Precharge\u003c\/td\u003e\n \u003ctd\u003e12 PSI\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eAir Valve\u003c\/td\u003e\n \u003ctd\u003eYes\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eBladder Material\u003c\/td\u003e\n \u003ctd\u003eButyl\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eBrand\u003c\/td\u003e\n \u003ctd\u003eWatts\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eBuy American Act Compliant\u003c\/td\u003e\n \u003ctd\u003eNO\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eColor\u003c\/td\u003e\n \u003ctd\u003eGray\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eDiameter\u003c\/td\u003e\n \u003ctd\u003e16 IN\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eEAN\u003c\/td\u003e\n \u003ctd\u003e098268219470\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eElectricity Required\u003c\/td\u003e\n \u003ctd\u003eNo\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eFuel Gauge\u003c\/td\u003e\n \u003ctd\u003eNo\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eInlet Connection Size\u003c\/td\u003e\n \u003ctd\u003e3\/4 IN\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eInlet Connection Size-Metric\u003c\/td\u003e\n \u003ctd\u003e20 MM\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eInlet Connection Type\u003c\/td\u003e\n \u003ctd\u003eMale Threaded\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eInlet Thread Type\u003c\/td\u003e\n \u003ctd\u003eNPT\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eLead Free\u003c\/td\u003e\n \u003ctd\u003eNO\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eLiner Material\u003c\/td\u003e\n \u003ctd\u003eDoes Not Apply To Product\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eMaximum Operating Temperature-Fahrenheit\u003c\/td\u003e\n \u003ctd\u003e220\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eMaximum Working Pressure-PSI\u003c\/td\u003e\n \u003ctd\u003e100\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eMount Type\u003c\/td\u003e\n \u003ctd\u003ePipe\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eOrientation\u003c\/td\u003e\n \u003ctd\u003eVertical \/ Horizontal\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003ePart Number\u003c\/td\u003e\n \u003ctd\u003e\u003cspan class=\"highlight\"\u003e\u003cspan class=\"highlight\"\u003e0066608\u003c\/span\u003e\u003c\/span\u003e\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eSeries\u003c\/td\u003e\n \u003ctd\u003eETX\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eStand Included\u003c\/td\u003e\n \u003ctd\u003eNo\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eTank Acceptance\u003c\/td\u003e\n \u003ctd\u003e6 Gallons at 12 PSI\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eTank Height\u003c\/td\u003e\n \u003ctd\u003e20 13\/16 IN\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eTank Material\u003c\/td\u003e\n \u003ctd\u003eCarbon Steel\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eTank Volume\u003c\/td\u003e\n \u003ctd\u003e15 Gallon\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/media.mainlinematerials.com\/files\/es-etx-etsx-pdf.pdf\" target=\"_blank\"\u003eSpecification Sheet - ETX\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e\n\u003cb\u003eUPC\u003c\/b\u003e - 098268219470","brand":"Watts","offers":[{"title":"Default Title","offer_id":44887702634696,"sku":"0066608","price":657.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0172\/0762\/3734\/files\/639004257830000000.jpg?v=1767122822","url":"https:\/\/www.mainlinematerials.com\/products\/watts-etx-90-part-of-the-etx-series","provider":"Mainline Materials","version":"1.0","type":"link"}
