Parker VS271NTA-4-4 Compression Male Run Tee 1/4 in Brass

Product Description

The PARKER VS271NTA-4-4 is a brass compression tube male run tee designed for connecting tubing runs in fluid and pneumatic systems. It features a Compression x MNPT x Compression end configuration, allowing a threaded male branch off a continuous compression tube run. The fitting carries a 1/4 inch NPTF thread and is rated to 150 psi maximum working pressure. Operating temperature range spans from -40 degrees F to 200 degrees F, making it suitable for a wide range of service environments. Licensed plumbers, HVAC technicians, and fluid-system mechanics install this type of fitting in refrigerant, fuel, air, and hydraulic tubing assemblies.

This fitting is used in residential and light commercial applications where a compression tube line must branch off to a male pipe thread port. Common install scenarios include brake and fuel line assemblies, pneumatic control lines, and HVAC refrigerant or oil tubing. The Compression x MNPT x Compression arrangement keeps the main tube run intact while adding a side male NPT takeoff. The 0.137 inch inside diameter suits standard 1/4 inch compression tubing. Meets D.O.T. FMVSS571.106, SAE J1131, and SAE J246 standards, which are frequently required in automotive and fluid-transfer applications.

Key Features

• Compression x MNPT x Compression end connections for in-line branch fittings without cutting the main run
• 1/4 inch NPTF thread standard for leak-resistant sealed connections
• Brass construction for corrosion resistance and reliable sealing under compression
• 150 psi maximum working pressure rating
• Wide temperature range: -40 degrees F to 200 degrees F
• Certified to D.O.T. FMVSS571.106, SAE J1131, and SAE J246

Compatibility

Designed as an OEM-style replacement or direct-install compression male run tee for 1/4 inch compression tube systems requiring a male NPT branch connection in fluid, pneumatic, or fuel line assemblies.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanic familiar with compression fittings and applicable codes. Depressurize and isolate the system completely before removing or installing any fitting. Compression fittings rely on proper ferrule seating and consistent torque applied with appropriate tubing wrenches — do not overtighten. Verify tubing is cut square, deburred, and fully seated before tightening the compression nut.
