Parker R46-02BK Miniature Air Regulator 1/4 Npt 60 Psi

Product Description

The PARKER R46-02BK is a miniature compressed air regulator designed to control downstream pressure in pneumatic systems. Built on Parker's R46 series platform, it features a 1/4 inch NPT port connection and regulates output pressure across a 0 to 60 psi range while accepting supply pressure up to 150 psi. The plastic body keeps weight low at 0.38 pounds, making it well suited for space-constrained panel or inline installations. Licensed HVAC technicians, industrial maintenance technicians, and pneumatic system integrators install this type of regulator when precise, stable downstream pressure is required in light-duty or miniature pneumatic circuits.

The R46-02BK is suited for compressed air applications in residential and light commercial environments. Its compact footprint — 2.06 inches wide by 3.43 inches high — allows it to fit in tight enclosures or manifold assemblies. Operating temperatures range from 40 degrees F to 125 degrees F, covering standard indoor pneumatic system conditions. Note that Parker lists water as a compatible fluid type for this regulator, making it applicable in light water-pressure regulation scenarios in addition to compressed air service. No pressure gauge is included, but a 1/4 inch gauge port is available if monitoring is required.

Key Features

• Miniature R46 series form factor — 2.06 inches wide by 3.43 inches high for space-constrained installations
• 1/4 inch NPT end connections for standard compressed air line integration
• 0 to 60 psi output pressure range with 150 psi maximum supply pressure rating
• Plastic body construction keeps unit weight at 0.38 pounds
• 1/4 inch gauge port included for optional downstream pressure monitoring
• Compatible with both compressed air and water fluid types

Compatibility

Designed as an OEM-style miniature regulator for compressed air and water pneumatic systems using 1/4 inch NPT connections where downstream pressure must be regulated to 60 psi or below from supply lines up to 150 psi.

Installation Notes

Installation should be performed by a qualified technician familiar with pneumatic or fluid control systems. Depressurize and lock out the supply line before installing or removing the regulator. Apply appropriate thread sealant to NPT connections per industry practice — do not over-torque plastic-bodied fittings. Verify downstream pressure with a calibrated gauge at the 1/4 inch gauge port before returning the system to service.
