{"product_id":"min-tnk-6x18-blue-polyglass","title":"Min Tnk, 6x18 Blue Polyglass","description":"\u003cp\u003eThis Pentair 6\" x 18\" blue Polyglass mineral tank is a compact, corrosion-resistant pressure vessel sized for small-volume water-treatment applications where space is at a premium. Its modest footprint makes it a frequent choice for point-of-use filters, small commercial setups, RO booster applications, and specialty media beds that simply do not require a full-size residential column. When you need treatment capability in a tight closet, under a counter, or alongside other equipment in a crowded mechanical area, a 6x18 tank fits where larger vessels cannot, opening up installation possibilities that bigger tanks would rule out.\u003c\/p\u003e\u003cp\u003ePolyglass tanks are built by winding fiberglass over a seamless polyethylene liner, producing a vessel that comfortably withstands typical residential and light-commercial operating pressures while completely resisting the rust and corrosion that eventually claim steel tanks. Just as importantly, the inert inner liner keeps the tank from affecting water chemistry, which matters when the vessel will hold carbon, calcite, or specialty filtration media that must perform without interference from the container around it. The blue exterior gives a clean, finished appearance in any equipment area and resists fading over years of service.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eNominal dimensions of 6\" diameter by 18\" height\u003c\/li\u003e\n\u003cli\u003eDurable Polyglass (fiberglass-wound) construction\u003c\/li\u003e\n\u003cli\u003eAttractive blue exterior finish\u003c\/li\u003e\n\u003cli\u003eCorrosion-resistant for long service life with treatment media\u003c\/li\u003e\n\u003cli\u003eChemically inert liner that will not alter treated water\u003c\/li\u003e\n\u003cli\u003eCompatible with standard control valves and distributor systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eBuilding your system\u003c\/h3\u003e\u003cp\u003ePair this tank with a compatible top-mount valve or filter head, an appropriate riser and distributor tube, and the media of your choice to build a tailored treatment column suited to your specific water problem. Before assembly, always confirm that the valve thread, distributor size, and intended media volume match the tank, and be sure to operate within the manufacturer's published pressure and temperature limits so the vessel performs safely throughout its life. The small size also makes this tank convenient for test setups, demonstration units, and specialty applications where a full column would be impractical. Whether you are assembling a compact new filter, building a point-of-use system, or replacing an existing small vessel, this Pentair 6x18 is a reliable, space-saving foundation for point-of-use and specialty filtration projects.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":45668838211637,"sku":"PT0618-B","price":98.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/4950\/2261\/files\/pt0618-b.jpg?v=1782535239","url":"https:\/\/watersoftenerplus.com\/pl-eu\/products\/min-tnk-6x18-blue-polyglass","provider":"Water Softener Plus","version":"1.0","type":"link"}
