Parker VS68AB-12-8 Compression Tube Connector Brass

Product Description

The PARKER VS68AB-12-8 is a brass compression tube connector designed to join tubing to a male NPT threaded port in fluid and pneumatic plumbing systems. It features a compression-style tube end on one side and a male NPTF threaded end on the other, providing a reliable, leak-resistant connection without soldering or flaring. The connector is rated for a maximum working pressure of 400 psi and handles temperatures from -65 degrees F to 250 degrees F, making it suitable for a broad range of industrial and mechanical service environments. Plumbers, pipefitters, and HVAC technicians install this fitting where tubing must terminate at an NPT-ported valve, manifold, or equipment stub-out.

This connector is well suited for use in hydraulic lines, pneumatic systems, fuel lines, and general fluid conveyance applications in both commercial and industrial settings. The NPTF thread standard ensures a pressure-tight mechanical seal at the threaded connection. With an inside diameter of 0.658 inches and a 1/2-14 thread size, it accommodates common tubing sizes used across plumbing, refrigeration, and light industrial piping installations.

Key Features

• Brass construction provides corrosion resistance and compatibility with a wide range of media
• Compression x MNPT end connections eliminate the need for soldering or flaring
• Rated to 400 psi maximum working pressure for reliable performance in pressurized systems
• Wide operating temperature range of -65 degrees F to 250 degrees F
• NPTF thread standard delivers a pressure-tight threaded seal
• Inside diameter of 0.658 inches suits standard tubing used in fluid and pneumatic lines

Compatibility

Designed as an OEM-style replacement or service fitting for compression-to-MNPT connections in residential and commercial plumbing, HVAC, and light industrial fluid systems using 1/2-14 NPTF threaded ports.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician. Depressurize and isolate the line completely before removing the existing fitting or installing this connector. Apply an appropriate thread sealant or PTFE tape to the NPTF male threads per the applicable IPC or IFGC guidelines for the service medium. Do not overtighten the compression nut, as excess force can deform the ferrule and compromise the seal.
