Parker VS68AB-6-8 Compression Tube Connector Brass

Product Description

The PARKER VS68AB-6-8 is a brass compression tube connector designed to join compression tubing to a male NPT threaded port. It provides a reliable, leak-resistant connection in fluid and pneumatic line assemblies. The fitting is rated to 400 psi maximum working pressure and handles temperatures from -65 degrees F to 250 degrees F. Constructed from brass, it resists corrosion in a wide range of media. The connector meets D.O.T. FMVSS571.106 and SAE J246 standards, making it suitable for brake and fluid system applications where compliance is required. It is installed by plumbers, HVAC technicians, and fleet maintenance professionals.

This compression-to-MNPT connector is used in hydraulic and pneumatic tubing assemblies across residential, commercial, and mobile equipment applications. The 1/2-14 NPTF thread size and compression end make it a standard choice for connecting copper, nylon, or poly tubing to NPT-ported valves, manifolds, and fittings. Its brass construction and dual-standard compliance make it particularly common in DOT-regulated brake and fuel line installations on commercial vehicles and trailers.

Installation Notes

This fitting is installed by licensed plumbers, HVAC technicians, or qualified fleet maintenance technicians. Always depressurize and drain the line before removing or installing compression fittings. Ensure tubing is cut square and deburred before seating in the compression end to achieve a proper seal. Follow applicable federal DOT regulations and SAE guidelines when installing in regulated brake or fuel line systems.
