Parker 62C-4-3 Compression Tube Reducer Brass Sae J-512

Product Description

The PARKER 62C-4-3 is a brass compression tube reducer designed to connect two compression-style tube ends of differing sizes within fluid and pneumatic line assemblies. It features a 3/8-24 inch thread size with compression-to-compression end connections, making it suitable for reducing tube diameter inline without welding or soldering. Rated to 300 psi maximum working pressure and a temperature range of -65 to 250 degrees F, this fitting handles demanding service conditions found in hydraulic, fuel, and instrumentation lines. It is installed by plumbers, HVAC technicians, and fluid systems technicians in both residential and light commercial applications.

The 62C-4-3 fits into compression tube assemblies where a step-down in line size is required. Its compact overall length of 1.29 inches makes it practical in tight plumbing or equipment enclosures. Common applications include fuel line routing, refrigeration tubing, hydraulic circuits, and instrumentation tubing runs where SAE J-512 compliance is required. The fitting is sold as a single unit and is appropriate for new installations and service replacements alike.

Compatibility

Designed as an OEM-style replacement or service fitting for compression tube assemblies requiring a 3/8-24 inch thread size reducer conforming to SAE J-512.

Installation Notes

Installation is performed by a licensed plumber, HVAC technician, or fluid systems technician. Depressurize and drain the line fully before removing the existing fitting or installing this reducer. Compression fittings require proper tube preparation — cut tubing square and deburr before seating the ferrule. Follow applicable codes such as ASME B31 or equipment manufacturer guidelines for torque and assembly procedure.
