Parker 270NTA-4-4 Compression Female Elbow 1/4 in Brass

Product Description

The PARKER 270NTA-4-4 is a brass compression tube female elbow designed to connect 1/4-inch outside diameter tubing to a female NPT port at a 90-degree angle. The fitting uses a compression end on one side and a female NPTF-threaded end on the other, creating a secure, leak-resistant joint without soldering or brazing. Rated to 150 psi maximum working pressure and a temperature range of -40 degrees F to 200 degrees F, this fitting is suited for refrigeration lines, pneumatic controls, instrumentation tubing, and similar low-pressure fluid or gas service applications. Brass construction provides corrosion resistance in a wide range of media.

This elbow fitting is used in residential and commercial HVAC systems, refrigeration equipment, pneumatic control circuits, and plumbing instrumentation where a direction change from tubing to a female-threaded port is required. The compression-to-FNPT configuration is common in field service and panel assembly work where a reusable, tool-assisted connection is preferred over permanent joints. Licensed HVAC technicians, refrigeration mechanics, and plumbers routinely use fittings of this type when routing copper or compatible soft tubing to valve bodies, gauges, or manifold blocks.

Key Features

• Compression x FNPT end connections allow tubing to be joined to female NPT-threaded ports at a 90-degree angle
• Brass material provides corrosion resistance and compatibility with a broad range of fluids and gases
• 150 psi maximum working pressure suitable for low-pressure pneumatic and fluid service
• Operating temperature range of -40 degrees F to 200 degrees F covers most HVAC and refrigeration ambient conditions
• NPTF thread standard supports pressure-tight connections without additional sealant tape in many applications
• Compact elbow geometry assists routing in tight spaces where a straight fitting will not clear

Compatibility

Designed as an OEM-style replacement or service fitting for systems using 1/4-inch outside diameter compression tubing terminated to female NPT ports, consistent with UNSPSC code 27121700 fluid-fitting classification.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified refrigeration mechanic. Shut off and depressurize the system before removing or installing any fittings. Ensure the compression ferrule is properly seated on the tubing before tightening the compression nut; do not overtighten, as brass fittings can distort. Verify thread compatibility and apply thread sealant per the applicable code and system fluid requirements before making up the NPTF end.
