Pro-source 4710302525PRO Air Regulator 1/4 Npt 120 Psi

Product Description

The PRO-SOURCE 4710302525PRO is a dial-type compressed air regulator designed to maintain consistent downstream pressure in pneumatic systems. It accepts supply pressure up to 120 psi and delivers an adjustable output across a range of 10 to 160 psi, making it suitable for a wide range of air-driven tools and equipment. The regulator features a brass body for durability and corrosion resistance in compressed air service. An integrated pressure gauge is included, allowing technicians to monitor regulated output without adding a separate gauge fitting. Operating temperature range runs from 32 to 122 degrees F. This unit is installed by pneumatic technicians, maintenance mechanics, and HVAC service professionals working with compressed air distribution systems.

This regulator is suited for use on compressed air lines in light industrial, commercial, and trade service environments. The 1/4 inch NPT port size makes it a common fit for tool drops, air supply manifolds, and equipment inlets that call for a quarter-inch threaded connection. It is appropriate for applications where regulated, consistent air pressure is required at a control point — such as spray equipment, pneumatic controls, or instrumentation supply lines. The included dial gauge port uses a 1/4 inch thread, matching standard gauge fittings already common in most shop and field setups.

Key Features

• Dial-type adjustment for precise, repeatable pressure setting
• 120 psi maximum supply pressure rating
• Adjustable output range of 10 to 160 psi
• Brass body construction for corrosion resistance in compressed air service
• Pressure gauge included with 1/4 inch gauge port
• Operating temperature range: 32 to 122 degrees F

Compatibility

Designed for use with compressed air systems using 1/4 inch NPT threaded connections. Suitable as an inline regulator on compressed air distribution lines, tool drops, and pneumatic equipment inlets within the rated pressure and temperature limits.

Installation Notes

Installation should be performed by a qualified pneumatic or mechanical technician. Depressurize the air line fully before removing any existing regulator or installing this unit. Apply thread sealant appropriate for compressed air service to the NPT threads before assembly — do not use PTFE tape beyond the thread area. Verify inlet pressure does not exceed the 120 psi maximum supply rating after startup.
