IMPA: 590823

Air Line Pressure Regulator with Pressure Gauge – 1/2" PT Connection

Maintain constant air pressure on pneumatic lines with this non-relieving pressure regulator. Designed for marine and industrial applications, it ensures stable output pressure for reliable tool operation. The integrated pressure gauge allows easy monitoring, and the 1/2" PT thread connection fits standard air line fittings.

With a maximum operating pressure of 140 psi (9.9 kgf/cm²) and a set pressure range of 7–123 psi (0.05–0.85 MPa), this regulator handles demanding conditions. The maximum operating temperature is 140°F (60°C), making it suitable for engine rooms and workshops.

Built for durability, this regulator is a direct replacement for IMPA 590823. Its compact design and easy adjustment knob simplify installation and use. Ideal for ship chandlers and maintenance crews.

Frequently Asked Questions

Is this regulator relieving or non-relieving?

This regulator is a non-relieving (non-vented) type, meaning it does not vent excess downstream pressure to the atmosphere. It maintains set pressure without bleeding air, ideal for applications where pressure stability is critical.

What type of thread does it have?

The connection thread is PT 1/2", which is a parallel pipe thread commonly used in marine and industrial pneumatic systems. It matches standard 1/2" BSP or NPT adapters with proper sealing.

Does it come with a pressure gauge?

Yes, a pressure gauge is included as a standard accessory with the unit, allowing you to monitor the regulated output pressure directly at the regulator.

What is the maximum operating temperature?

The maximum operating temperature is 60°C (140°F), making it suitable for use in engine rooms and other warm environments typically found on ships.
