Parker VS176NTA-4-2 Compression Tube Adapter Brass

Product Description

The PARKER VS176NTA-4-2 is a brass compression tube adapter designed to connect a 1/4 inch outside diameter tube to a 1/8 inch NPTF threaded port. It transitions between compression tube fittings and threaded pipe connections in pneumatic and fluid line applications. Built to DOT FMVSS571.106, SAE J1131, and SAE J246 standards, this adapter is rated for a maximum working pressure of 150 psi and a temperature range of -40 to 200 degrees F. Licensed plumbers, HVAC technicians, and fluid systems mechanics install this fitting where a tube-to-thread transition is required in a tight, leak-resistant connection.

This adapter is suited for use in compressed air lines, hydraulic tubing assemblies, and refrigerant or fuel line applications where a 1/4 inch OD tube must mate with a 1/8 inch NPTF threaded port. Its brass construction provides corrosion resistance and durability in both mobile equipment and stationary systems. The DOT and SAE certifications make it appropriate for brake and fuel line service on commercial vehicles as well as general industrial and HVAC plumbing installations.

Compatibility

Designed as an OEM-style replacement or direct-fit adapter for systems requiring a 1/4 inch OD compression tube to 1/8 inch NPTF threaded port connection in DOT- and SAE-compliant fluid line assemblies.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified fluid systems mechanic. Depressurize and isolate the line before removing any existing fitting. Ensure the mating NPTF port and tube end are clean, undamaged, and free of debris before making up the connection. Apply thread sealant appropriate for the service fluid and follow applicable SAE and DOT guidelines for torque and assembly procedures.
