Parker 229-6-4 Barbed Male Elbow 1/4-18 Brass Fitting

Product Description

The PARKER 229-6-4 is a barbed tube male elbow fitting designed for fluid and pneumatic line connections in trade plumbing, HVAC, and industrial applications. Constructed from brass, this fitting features a male threaded end sized at 1/4-18 and a barbed end sized for a 0.25 inch tube inside diameter. The elbow configuration allows directional changes in tubing runs without the need for additional adapters. The brass construction offers corrosion resistance and reliable sealing performance in low to medium pressure systems. This fitting is installed by licensed plumbers, HVAC technicians, and pipefitters working on fluid transfer and pneumatic control lines.

This fitting is suited for residential and light commercial applications where a tubing line must connect to a male-threaded port at a 90-degree angle. Typical use cases include refrigerant-adjacent control lines, water supply tubing connections, and compressed air distribution in equipment panels. The 1/4-18 thread size is a standard taper pipe thread (NPT) commonly found on valves, manifolds, and equipment fittings across HVAC and plumbing systems. The barbed end secures flexible tubing for a leak-resistant connection when used with an appropriate clamp or ferrule.

Key Features

• Brass construction for corrosion resistance in fluid and air service
• Male elbow configuration for 90-degree directional changes in tubing runs
• 1/4-18 NPT male thread for connection to standard threaded ports
• 0.25 inch barbed tube inside diameter for secure flexible tubing retention
• Compact single-piece design reduces potential leak points

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 1/4-18 NPT male threaded ports and 0.25 inch ID flexible tubing in HVAC, plumbing, and pneumatic control applications.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or pipefitter in accordance with applicable codes including the IPC and IFGC. Depressurize and isolate the line before removing or installing any fitting. Apply thread sealant or PTFE tape to the male NPT threads before tightening. Secure the barbed end with an appropriate hose clamp or crimp ferrule rated for the application pressure and fluid type.
