Parker VS68AB-8-8 Compression Tube Connector Brass Nptf

Product Description

The PARKER VS68AB-8-8 is a brass compression tube connector designed to join compression-end tubing to a male NPT (MNPT) threaded port. It provides a secure, leak-resistant mechanical connection without requiring flare preparation, making it a practical choice for pneumatic and fluid-line assemblies. The connector is rated to 400 psi maximum working pressure and handles temperatures from -65 degrees F to 250 degrees F. Fabricated from brass, it meets D.O.T. FMVSS571.106 and SAE J246 standards, confirming suitability for regulated transport and fluid-system applications. Plumbers, HVAC technicians, and fluid-system mechanics install this type of fitting where a quick, reliable compression-to-threaded transition is needed.

This connector is suited for use in hydraulic, pneumatic, and fluid-transfer lines found in both mobile and stationary equipment. The compression x MNPT end configuration makes it a common choice for connecting copper or nylon tubing to NPT-ported valves, manifolds, or equipment housings. Its 1/2-14 NPTF thread size is a standard dimension seen in a wide range of plumbing and mechanical fluid-system builds, including air brake systems and other D.O.T.-governed assemblies.

Key Features

• Compression x MNPT end connections for tubing-to-threaded-port transitions
• Brass construction for corrosion resistance and machinability
• 400 psi maximum working pressure
• Operating temperature range: -65 degrees F to 250 degrees F
• Meets D.O.T. FMVSS571.106 and SAE J246 standards
• 1/2-14 NPTF thread size for standard NPT port compatibility

Compatibility

Designed as an OEM-style compression-to-MNPT fitting for pneumatic, hydraulic, and fluid-transfer line applications requiring D.O.T. FMVSS571.106 and SAE J246 compliance.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC mechanics, or fluid-system technicians. Depressurize and isolate the line fully before disassembling any existing fitting or installing this connector. Ensure the compression nut and ferrule are seated squarely on the tubing before tightening to avoid leaks or tube deformation. Follow applicable system codes and equipment manufacturer torque guidance when threading into NPT ports.
