Parker 270NTA-6-4 Compression Female Elbow 1/4 in Fnpt

Product Description

The PARKER 270NTA-6-4 is a brass compression tube female elbow fitting designed to connect tubing to a female NPT port at a 90-degree angle. It accepts a compression-style tube connection on one end and a 1/4-inch FNPT threaded connection on the other. Rated for up to 150 psi working pressure, this fitting is suited for fluid and gas line applications in HVAC, refrigeration, instrumentation, and plumbing systems. The brass construction provides reliable corrosion resistance across a wide temperature range. Licensed plumbers, HVAC technicians, and pipefitters install this fitting during both new construction and service work.

This fitting is used in residential and light commercial applications where tubing must transition to a female NPT port. Common scenarios include connecting copper or compatible soft tubing to valves, gauges, manifolds, or control devices. The compression-by-FNPT configuration eliminates the need for soldering at the tube end, making it practical for field repairs and tight-access installations. It is rated for service from -40 degrees F to 200 degrees F, covering typical operating ranges in HVAC and refrigeration piping.

Key Features

• 90-degree elbow configuration routes tubing cleanly in confined spaces
• Compression x FNPT end connections — no soldering required at the tube end
• Brass construction for corrosion resistance in fluid and gas service
• 150 psi maximum working pressure rating
• Wide temperature range: -40 degrees F to 200 degrees F
• 1/4-inch NPTF thread standard for reliable pressure-tight engagement

Compatibility

Designed as an OEM-style compression fitting for use in HVAC, refrigeration, instrumentation, and plumbing systems requiring a tube-to-female-NPT elbow connection at 1/4-inch thread size.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off system pressure and depressurize the line before disassembly or fitting installation. Hand-tighten the compression nut onto the tube, then advance with a wrench per standard compression fitting practice — do not overtighten, as brass fittings can be damaged by excessive torque. Apply appropriate thread sealant or PTFE tape to the FNPT threads in accordance with local plumbing codes and the fitting manufacturer's guidance.
