Parker VS68NTA-12-8 Compression Tube Connector 1/2 in

Product Description

The PARKER VS68NTA-12-8 is a brass compression tube connector designed to join tubing to a male NPT threaded port. It provides a secure, leak-resistant connection in fluid and pneumatic line assemblies. The fitting uses a compression-style end connection on one side and a male NPTF thread on the other, making it a reliable choice for connecting soft tubing to threaded ports in a wide range of system configurations. With a maximum working pressure of 150 psi and a service temperature range of -40 degrees F to 200 degrees F, it suits demanding trade applications. Installation is performed by licensed plumbers, HVAC technicians, and fluid-system mechanics working with compressed air, hydraulic, or fuel line assemblies.

This connector is suited for use in residential and light commercial applications where a compression-to-MNPT transition is needed. Its brass construction provides corrosion resistance in moderate-duty fluid handling and pneumatic systems. The 1/2 inch NPTF thread size and 0.523 inch inside diameter accommodate standard tubing in DOT-compliant brake line and fluid transfer assemblies. It meets D.O.T. FMVSS571.106, SAE J1131, and SAE J246 standards, making it appropriate for regulated vehicle and industrial fluid system installations.

Key Features

• Brass construction offers corrosion resistance in fluid and pneumatic service
• Compression x MNPT end connections for tubing-to-threaded-port transitions
• 150 psi maximum working pressure for reliable performance in moderate-duty systems
• Wide temperature range: -40 degrees F to 200 degrees F
• Meets D.O.T. FMVSS571.106, SAE J1131, and SAE J246 standards
• 1/2 inch NPTF thread with 0.523 inch inside diameter for standard tubing fitment

Compatibility

Designed as an OEM-style replacement or direct-install compression tube connector for fluid and pneumatic systems requiring a 1/2 inch NPTF male thread and compression-style tubing connection in DOT- and SAE-compliant installations.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or fluid-systems mechanic. Depressurize and isolate the line before disconnecting any existing fittings. Hand-tighten the NPTF thread first, then apply thread sealant appropriate for the service fluid before final torque. Ensure tubing is cut square and fully seated in the compression end before tightening the compression nut to avoid leaks.
