Pro-source 22070037PRO Frl Pressure Gauge 0-300 Psi

Product Description

The PRO-SOURCE 22070037PRO is a replacement pressure gauge designed for use with FRL (filter-regulator-lubricator) filter units in compressed air and pneumatic systems. Constructed from glass filled nylon, this gauge provides a lightweight yet durable solution for monitoring line pressure in industrial and commercial pneumatic installations. It reads from 0 to 300 psi and fits 3/8 inch pipe connections. Pneumatic technicians and maintenance professionals install this gauge as a direct accessory replacement when an existing filter-mounted gauge becomes damaged or unreadable, restoring accurate pressure monitoring without replacing the entire FRL assembly.

This gauge is intended for use with compatible FRL filter bodies in pneumatic systems where line pressure must be monitored at the point of filtration. Typical applications include air compressor distribution lines, production equipment air supplies, and maintenance shop pneumatic systems. It is suited for both light industrial and general commercial environments where a compact, readable pressure indicator is required at the filter stage of an FRL assembly.

Key Features

• Glass filled nylon construction offers corrosion resistance and reduced weight compared to metal-bodied gauges
• 0 to 300 psi pressure range covers a wide span of standard compressed air system operating pressures
• 3/8 inch pipe size connection for straightforward integration with compatible filter bodies
• Compact form factor at 3 inches long, 3 inches tall, and 2 inches wide for installation in tight enclosures or panel-mounted FRL setups
• Designed as a direct accessory replacement, minimizing downtime during filter maintenance cycles

Compatibility

Designed as an OEM-style accessory replacement pressure gauge for FRL filter units requiring a 3/8 inch pipe connection and a 0 to 300 psi range.

Installation Notes

Installation should be performed by a qualified pneumatic or mechanical technician. Depressurize and lock out the air supply line completely before removing or installing any FRL component. Use appropriate thread sealant on the pipe threads as required by the installation and applicable codes, and avoid overtightening the gauge into the filter body to prevent cracking the nylon housing. Verify the system pressure does not exceed the 300 psi maximum rating after restoring air supply.
