Pro-source 4710302535PRO Air Regulator 120 Psi 1/4 Npt

Product Description

The PRO-SOURCE 4710302535PRO is a dial-type compressed air regulator designed to control downstream air pressure in pneumatic systems. Built from zinc construction, this regulator features a 1/4 inch NPT port and handles supply pressures up to 120 psi. An integrated pressure gauge is included, allowing technicians to monitor regulated output without adding additional instrumentation. The unit operates across a temperature range of 32 to 122 degrees F, making it suitable for indoor shop environments and general-purpose compressed air lines. It is a compact unit measuring 1.97 inches wide by 1.97 inches high, well suited for installations where space is limited.

This regulator is used in compressed air distribution systems found in maintenance shops, light manufacturing, and HVAC or plumbing service vehicles. It is a standard inline regulator for applications requiring controlled air pressure delivered to tools, actuators, or pneumatic controls. The dial adjustment allows the technician to set output pressure precisely within the operating range, making it practical for both stationary bench setups and portable compressor rigs.

Key Features

• Dial-type adjustment for direct, readable pressure control
• Integrated pressure gauge included — no additional gauge port fitting required
• 1/4 inch NPT port fits standard compressed air line fittings
• 120 psi maximum supply pressure capacity
• Zinc body construction for durability in shop environments
• Compact 1.97 inch by 1.97 inch profile for tight installation spaces

Compatibility

Designed as a general-purpose inline air regulator for compressed air systems using 1/4 inch NPT connections with supply pressures at or below 120 psi.

Installation Notes

Installation is typically performed by a qualified maintenance technician or pipefitter. Depressurize and lock out the compressed air supply line before installing or removing the regulator. Apply thread sealant appropriate for compressed air service to NPT threads before making connections. Verify that supply pressure does not exceed 120 psi and that ambient operating temperature remains within the rated range of 32 to 122 degrees F.
