Parker R46-03CK Miniature Air Regulator 3/8 Npt 150 Psi

Product Description

The PARKER R46-03CK is a miniature compressed air regulator designed to reduce and maintain downstream pressure in pneumatic systems. Part of the Parker R46 series, it accepts supply pressures up to 150 psi and delivers a regulated output range of 0 to 125 psi. The body is constructed of plastic, keeping weight low at 0.38 pounds. Its 3/8 inch NPT end connections suit a wide range of compressed air lines. Licensed HVAC technicians, industrial maintenance techs, and plumbing professionals install this regulator where space is limited and precise low-pressure control is required.

The R46-03CK is suited for compact pneumatic control applications in both light commercial and residential settings. It handles fluid type water in addition to compressed air, making it adaptable to low-pressure water regulation tasks. The operating temperature range of 40 to 125 degrees F covers most indoor mechanical room and utility environments. With overall dimensions of 2.06 inches wide by 3.43 inches high, it fits into tight panel or inline installations where a full-size regulator is impractical.

Key Features

• Miniature form factor: 2.06 inches wide by 3.43 inches high for space-constrained installs
• Maximum supply pressure of 150 psi with output range of 0 to 125 psi
• 3/8 inch NPT end connections for standard compressed air line compatibility
• 1/4 inch gauge port thread size for optional downstream pressure gauge addition
• Plastic body construction reduces weight to 0.38 pounds
• Operating temperature range of 40 to 125 degrees F

Compatibility

Designed as an OEM-style inline replacement for miniature compressed air regulators with 3/8 inch NPT connections and 150 psi maximum supply pressure ratings in pneumatic control systems.

Installation Notes

Installation should be performed by a qualified technician familiar with compressed air or pneumatic system service. Depressurize the supply line completely before removing or installing the regulator. Verify that downstream equipment pressure ratings are compatible with the regulator output range before pressurizing. Follow applicable local codes and the system manufacturer guidelines for thread sealant use on NPT fittings.
