Marquest MTG-22060SB-PVC Pool Spa Filter Gauge, 0-60 PSI, PVC Isolator, Lower Mount, 1/4" Male NPT Thread

The Marquest Scientific Pool Spa Filter Gauge was engineered to provide a no fuss, high quality solution to the pool and spa industry where typical filter economy pressure gauges are overcome by a variety of stresses causing them to fail prematurely. The fully assembled unit is comprised of the following: (1) Wika 212.53 Stainless Case/Brass Internals 2.5" Dia. Gauge, Glycerin Filled Case. 2.5% Accuracy Full Span (2) Marquest PVC Mini Tuff Guard, Composite PTFE/FKM pressure sensing diaphragm,1/4" Male NPT lower mount connection (3) The internals of the assembly are vacuum filled with Aqueous Glycerin which eliminates all air allowing the diaphragm to simply transmit the pressure accurately to the pool filter gauge. The gauge guard provides a compatible, protective barrier between pool process fluid and the pool filter gauge. No Corrosion, Dampened Vibration, Long Life.
