Parker 05R213AD Air Regulator 3/8 Npt 300 Psi 40 Cfm

Product Description

The PARKER 05R213AD is an economy-series compressed air regulator designed to maintain consistent downstream pressure in pneumatic systems. Built from zinc with a 3/8-inch NPT port, it accepts supply pressure up to 300 psi and delivers regulated output across a 2 to 125 psi adjustment range. Maximum air flow is rated at 40 CFM. A built-in relief function vents excess pressure when the regulator is adjusted downward, protecting downstream equipment. Licensed plumbers, pipefitters, and industrial maintenance technicians are the typical installers for this type of inline pressure control device.

The 05R213AD fits into compressed air distribution systems where downstream pressure must be reduced and stabilized from a higher supply. It is suited for light-duty to medium-duty shop air lines, pneumatic tool circuits, and automated production equipment where a compact economy regulator meets pressure and flow requirements. The modular connection feature allows it to be paired with compatible Parker 05 Series filter and lubricator bodies to build a filter-regulator-lubricator assembly. Operating fluid is compressed air only, with a minimum rated temperature of 32 degrees F.

Key Features

• 3/8-inch NPT end connections for standard compressed air line integration
• 300 psi maximum supply pressure with a 2 to 125 psi regulated output range
• 40 CFM maximum air flow supports pneumatic tools and automation circuits
• Built-in relief function automatically vents downstream pressure on adjustment
• Modular connection compatible with Parker 05 Series components for FRL assembly
• Zinc body construction for lightweight, corrosion-resistant service

Compatibility

Designed as an OEM-style economy regulator within the Parker 05R Series, compatible with modular Parker 05 Series filter and lubricator units for inline compressed air system assemblies.

Installation Notes

Installation should be performed by a qualified pipefitter or industrial maintenance technician familiar with compressed air system safety procedures. Depressurize and lock out the air supply upstream before connecting or disconnecting the regulator. Apply appropriate thread sealant to NPT connections per shop or facility standards, and verify all fittings are leak-free before returning the system to service. Do not exceed the 300 psi maximum supply pressure rating.
