{"product_id":"eastman-thermal-expansion-tank","title":"Eastman Thermal Expansion Tank","description":"\u003cp\u003eThe Eastman thermal expansion tank is designed to prevent dangerous build-ups of pressure in your water heater tank. These thermal expansion tanks are available in 2 and 4.5-gallon sizes. The Eastman thermal expansion tank stops hot water from backflowing into the cold water line while preventing hot water from escaping through the pressure relief valve and onto the floor, addressing the constant fluctuations in water pressure that can be dangerous and potentially damage your water heater tank permanently. Recommended for homes with a closed-loop water supply system, this product comes with a 6-year limited warranty and is factory pre-charged at 40 psi. It complies with NSF-61 and Lead-Free law, and it is UPC approved.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures \u0026amp; Benefits\u003c\/strong\u003e \u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFor use in 30 gal. to 160 gal. water heater tanks.\u003c\/li\u003e\n\u003cli\u003eFactory pre-charged at 40 psi.\u003c\/li\u003e\n\u003cli\u003ePrevents dangerous pressure build-ups.\u003c\/li\u003e\n\u003cli\u003eFor installation on residential water heaters.\u003c\/li\u003e\n\u003cli\u003e304 Stainless Steel fittings.\u003c\/li\u003e\n\u003cli\u003eBuilt with a butyl rubber diaphragm.\u003c\/li\u003e\n\u003cli\u003eMax operating temperature of 210° F.\u003c\/li\u003e\n\u003cli\u003eMax working pressure of 150 psi.\u003c\/li\u003e\n\u003cli\u003e6 year warranty.\u003c\/li\u003e\n\u003cli\u003e3\/4\" MIP connection.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Eastman","offers":[{"title":"2 Gal (60022)","offer_id":51793257660647,"sku":"20301321","price":45.49,"currency_code":"USD","in_stock":true},{"title":"4.5 Gal (60023)","offer_id":51495629422823,"sku":"20301339","price":73.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0672\/1536\/0231\/files\/product-media-458748.jpg?v=1771366850","url":"https:\/\/fletcherlawnandgarden.com\/products\/eastman-thermal-expansion-tank","provider":"Fletcher Lawn \u0026 Garden Hardware","version":"1.0","type":"link"}
