Winters PFQ805 Liquid Fillable Pressure Gauge 0-160 Psi

Product Description

The WINTERS PFQ805 is a liquid fillable analog pressure gauge designed for accurate pressure monitoring in plumbing, HVAC, and industrial piping systems. It features a 2.5-inch diameter dial with a dual-scale readout and a measurement range of 0 to 160 psi. The case is constructed from 304 stainless steel, and all wetted parts are brass. The glycerine-filled design dampens needle vibration and reduces wear on internal components, making it suitable for systems with pulsating or fluctuating pressures. Accuracy is rated at 1.5 percent of full scale per ASME B40.100. This gauge is installed by licensed plumbers, HVAC technicians, and pipefitters.

The PFQ805 is suited for residential and light commercial applications including water supply lines, hydronic heating systems, air compressors, and pump discharge monitoring. The lower-mount NPT connection allows for direct inline or tee installation on vertical pipe runs. The glycerine fill and polycarbonate lens make it appropriate for environments with moderate vibration or moisture exposure. It ships as a single unit and is intended as a replacement or new-installation gauge for systems requiring a compact 2.5-inch dial format.

Key Features

• Glycerine-filled construction dampens needle vibration for stable readings under pulsating pressure
• 304 stainless steel case provides corrosion resistance in wet or humid environments
• Brass wetted parts compatible with water, light oils, and common HVAC fluids
• Dual-scale analog dial reads 0 to 160 psi with 1.5 percent full-scale accuracy
• Lower-mount 1/4-inch NPT connection for direct pipe or tee installation
• Polycarbonate lens with IP65-rated enclosure for moisture and dust resistance

Compatibility

Designed as an OEM-style replacement or new-installation gauge for residential and commercial plumbing, hydronic, and HVAC systems requiring a 2.5-inch lower-mount NPT pressure gauge rated to 160 psi.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician. Shut off system pressure and depressurize the line completely before removing any existing gauge or fitting. Apply thread sealant or PTFE tape to the NPT threads per local plumbing code requirements. Do not over-tighten the brass connection; use a wrench on the hex fitting body, not the gauge case, to avoid damaging internal components.
