Parker VS68NTA-12-12 Compression Tube Connector 3/4 in

Product Description

The PARKER VS68NTA-12-12 is a brass compression tube connector designed for joining tubing to male NPT threaded ports in fluid and pneumatic line applications. The fitting features a compression inlet on one end and a 3/4-inch male NPTF thread on the other, providing a reliable, leak-resistant mechanical connection without soldering or flaring. Rated to 150 psi maximum working pressure and compatible with temperatures ranging from -40 degrees F to 200 degrees F, this connector meets D.O.T. FMVSS571.106, SAE J1131, and SAE J246 standards. It is suited for plumbing, hydraulic, and fluid-transfer assemblies where DOT-compliant fittings are required.

This connector is used in mobile equipment, commercial vehicle brake and fluid systems, and industrial plumbing assemblies where compression-to-NPT transitions are needed. The brass construction offers corrosion resistance in water, air, and compatible fluid service. Installers working on DOT-regulated vehicle systems or industrial fluid lines will find this fitting appropriate for both new installations and repair work on existing compression tubing runs.

Key Features

• Compression x MNPT end connections for tool-free tubing attachment to threaded ports
• Brass construction provides corrosion resistance and durability in fluid service
• Rated to 150 psi maximum working pressure
• Wide temperature range: -40 degrees F to 200 degrees F
• Meets D.O.T. FMVSS571.106, SAE J1131, and SAE J246 standards
• 3/4-inch NPTF thread for secure, pressure-rated threaded connection

Compatibility

Designed as a standard compression-to-MNPT transition fitting for use in DOT-compliant fluid and pneumatic line assemblies on commercial vehicles and industrial equipment where 3/4-inch NPTF threaded ports and compression tubing with 0.523-inch inside diameter are specified.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or hydraulic technician familiar with compression fitting assembly procedures. Depressurize and isolate the fluid circuit completely before removing or installing any fittings. Compression fittings require proper tubing preparation including square cuts and clean, deburred ends to achieve a leak-free seal. Thread engagement should follow NPTF sealing practices per applicable standards; do not overtighten, as brass threads can be damaged.
