Parker 270AB-6-6 Compression Female Elbow 3/8-18 Fnpt

Product Description

The PARKER 270AB-6-6 is a brass compression tube female elbow fitting designed to connect compression tubing to a female NPT port at a 90-degree angle. It is rated for a maximum working pressure of 400 psi and handles temperatures from -65 degrees F to 250 degrees F, making it suitable for demanding fluid and pneumatic line applications. The fitting uses a 3/8-18 NPTF thread on the female end and a compression connection on the tube end. It meets D.O.T. FMVSS571.106 and SAE J246 standards, confirming its use in vehicular and fluid power systems. Licensed plumbers, HVAC technicians, and fleet maintenance professionals are the primary installers.

This fitting is used in hydraulic, pneumatic, and fluid transfer systems where a tubing run must change direction and terminate into a female threaded port. Common applications include brake line and air brake assemblies, compressed air systems, fuel lines, and refrigeration or HVAC tubing circuits. Its brass construction provides corrosion resistance in both wet and dry service environments. The -65 degrees F minimum temperature rating supports cold-climate installations and low-temperature fluid service.

Key Features

• 90-degree elbow configuration routes tubing into a female NPT port without additional adapters
• Brass construction offers corrosion resistance and compatibility with a wide range of fluid media
• Rated to 400 psi maximum working pressure for reliable performance in pressurized systems
• Operating temperature range of -65 degrees F to 250 degrees F supports extreme service conditions
• Meets D.O.T. FMVSS571.106 and SAE J246 standards for vehicular and fluid power applications
• 3/8-18 NPTF thread ensures a pressure-tight seal on the female port end

Compatibility

Designed as an OEM-style compression fitting for fluid power, pneumatic, and vehicular brake line systems requiring a 3/8-18 NPTF female threaded port connection with a compression tube inlet.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or fleet maintenance professional familiar with compression fittings and NPT thread connections. Shut off and depressurize the system completely before removing any existing fittings or tubing. Do not overtighten the compression nut, as brass fittings can be damaged by excessive torque. Verify that tubing is cut cleanly and squarely and that the compression sleeve is seated correctly before pressurizing the system.
