Parker 238-4-4 Barbed Tube Solder Connector

Product Description

The PARKER 238-4-4 is a barbed tube solder connector designed for use in fluid and refrigerant line assemblies where a secure, permanent tube-to-fitting joint is required. Constructed from brass, this fitting accepts tubing with an inside diameter of 0.17 inches and an outside diameter of 0.25 inches. The barbed design provides mechanical retention during the soldering process, keeping the tube positively seated before and during heat application. It is well suited for HVAC, refrigeration, and plumbing applications where copper or compatible soft tubing is joined by soldering. Installation is typically performed by licensed HVAC technicians or plumbers working on low-pressure line sets and fluid circuits.

This connector is used in residential and light commercial systems where small-diameter tubing connections are required. It is appropriate for applications involving refrigerant piping, condensate lines, or fluid transfer circuits that call for a soldered brass fitting. The single-piece barbed solder connector simplifies assembly by combining mechanical bite retention with a brazed or soldered permanent seal.

Key Features

• Brass construction provides corrosion resistance and compatibility with copper tubing
• Barbed design holds tubing in place during soldering for consistent joint alignment
• Inside diameter of 0.17 inches accommodates small-bore tubing applications
• Outside diameter of 0.25 inches for standard quarter-inch tubing fitment
• Compact, lightweight form factor at 0.01 pounds

Compatibility

Designed as an OEM-style replacement or service fitting for small-diameter copper or compatible soft tubing assemblies requiring a soldered brass barbed connector.

Installation Notes

Installation should be performed by a qualified HVAC technician or licensed plumber. Shut off all system pressure and depressurize the line before cutting or connecting tubing. Clean and flux all mating surfaces per standard soldering practice before applying heat. Follow applicable mechanical and plumbing codes, including IFGC and IPC guidelines, when working on pressurized fluid or refrigerant systems.
