Min Tnk, 12x48 Natural Poly Glass

Pentair's 12 x 48 Natural Poly Glass Mineral Tank (PT1248-A) is a workhorse pressure vessel for residential and light-commercial water treatment. Measuring 12 inches in diameter by 48 inches tall, it provides the media chamber for water softeners, backwashing filters, and a wide range of conditioning systems. The natural, translucent finish makes it easy to gauge media levels at a glance, a small convenience that installers genuinely appreciate during media loading and routine inspection of the system.

Poly glass tanks pair a seamless inner polyethylene liner with a fiberglass-reinforced outer wrap, delivering the pressure rating needed for whole-house service while resisting the rust and pitting that plague metal vessels. That construction is precisely why this style of tank has become the standard for modern softeners and filters across the United States. The seamless liner gives water nothing to corrode, and the filament-wound exterior provides the hoop strength to handle everyday household pressure swings without fatigue.
