Parker 68VL-12-8 Compression Tube Connector 1/2-14 Brass

Product Description

The PARKER 68VL-12-8 is a brass compression tube connector designed to join compression tubing to a male NPT threaded port in fluid and pneumatic systems. The connector uses Parker's Vibra-Lok compression style, which provides a secure, vibration-resistant seal without the need for additional fittings or thread sealant on the compression end. Rated to 100 psi maximum working pressure and suitable for operating temperatures from -30 degrees F to 275 degrees F, this connector is built for reliable performance in demanding industrial and mechanical service environments. It is installed by licensed plumbers, pipefitters, and mechanical contractors working on hydraulic, pneumatic, or fluid transfer systems.

This connector is suited for residential and commercial applications where a compression tube end must transition to a male NPT threaded connection. Typical installations include fluid control panels, pneumatic instrumentation lines, and equipment plumbing where vibration resistance is a priority. The Vibra-Lok compression design reduces the risk of loosening under cyclic vibration, making it appropriate for mobile equipment, compressor lines, and similar service environments. The connector meets ISO 6149 and SAE J1926 standards, supporting use in systems where conformance to these specifications is required.

Key Features

• Vibra-Lok compression style provides vibration-resistant tube retention without secondary locking components
• Brass construction offers corrosion resistance and compatibility with a wide range of fluids
• Compression x MNPT end connections allow direct transition from tube to male NPT threaded port
• Rated to 100 psi maximum working pressure
• Meets ISO 6149 and SAE J1926 standards
• Operating range of -30 degrees F to 275 degrees F supports diverse service conditions

Compatibility

Designed as an OEM-style replacement or new-installation compression connector for fluid and pneumatic systems requiring a 1/2-14 inch compression-to-MNPT transition conforming to ISO 6149 and SAE J1926 standards.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, or mechanical technician. Depressurize and isolate the fluid or pneumatic system completely before removing any existing fittings or installing this connector. Ensure the compression tube end is cut cleanly and squarely and is free of burrs before seating in the fitting. Follow applicable codes and the system manufacturer's torque and assembly guidelines for NPT threaded connections.
