Parker 6FEL6N-B Compression Female Elbow 3/8 in Brass

Product Description

The PARKER 6FEL6N-B is a brass compression tube female elbow fitting designed to connect 3/8 inch OD tubing to a female NPT port at a 90-degree angle. The compression end grips and seals the tube mechanically, while the FNPT end threads into a standard female-tapered pipe port. Rated to 2300 psi maximum working pressure, this fitting is built for demanding fluid and instrumentation systems. It is installed by licensed plumbers, HVAC technicians, and instrumentation mechanics working on refrigerant lines, compressed air systems, hydraulic circuits, and similar pressure-bearing tube runs.

The 6FEL6N-B is suited for residential and light commercial plumbing and HVAC applications where a tube-to-pipe directional change is required. Common install scenarios include connecting copper or brass tubing to valve bodies, manifolds, or equipment ports that carry a female NPT inlet. The compression style end allows installation without soldering or flaring, making it practical for field service and tight-access installations.

Key Features

• 2300 psi maximum working pressure for high-demand fluid system service
• Compression x FNPT end connections allow tube-to-pipe transitions without soldering or flaring
• 90-degree female elbow configuration for directional changes in tight spaces
• Brass construction for corrosion resistance and reliable sealing in plumbing and HVAC environments
• 3/8 inch tube OD compression end paired with a female NPT threaded port

Compatibility

Designed as an OEM-style compression fitting for use with 3/8 inch OD tubing in systems with female NPT ports. Cross-references to Swagelok part number B-600-8-6 as noted in manufacturer data.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician. Depressurize and isolate the system completely before removing or installing any compression fittings. Hand-tighten the compression nut onto the tube, then use a properly sized wrench to complete the turn as specified by the fitting manufacturer — do not overtighten, as over-compression can deform the ferrule and cause leaks. Apply thread sealant or PTFE tape to the FNPT threads in accordance with applicable IPC or IFGC code requirements for the fluid being carried.
