Norgren R06-221-RNKA Air Regulator 1/4 Inch Npt

Product Description

The NORGREN R06-221-RNKA is a compressed air regulator designed to maintain consistent downstream pressure in pneumatic systems. It features a 1/4 inch NPT port and does not include a pressure gauge. This regulator is used to reduce and stabilize supply-line pressure to protect downstream equipment and ensure reliable system operation. Licensed HVAC technicians, pneumatic system technicians, and industrial maintenance professionals typically install and service this component as part of air preparation and distribution assemblies.

This regulator is suited for light to medium-duty compressed air applications in residential and commercial settings. It fits standard 1/4 inch NPT inline installations where pressure regulation is required ahead of pneumatic tools, actuators, solenoid valves, or other air-operated equipment. Its compact form factor makes it appropriate for space-constrained panel or manifold installations.

Key Features

• 1/4 inch NPT port size for standard inline installation
• Regulator-only configuration — no pressure gauge included
• Compact and lightweight at 0.2 pounds
• Designed for consistent downstream pressure control in pneumatic circuits
• Single-unit packaging suitable for replacement or service applications

Compatibility

Designed as an OEM-style replacement regulator for pneumatic systems using 1/4 inch NPT air line connections.

Installation Notes

Installation should be performed by a qualified technician familiar with compressed air system servicing. Before installing, shut off and bleed the compressed air supply line completely to relieve system pressure. Apply thread sealant tape to NPT threads per standard practice and torque fittings by hand before using a wrench to avoid over-tightening. Verify downstream pressure setpoint after installation with an appropriate test gauge before returning the system to service.
