Parker 60VLV-4 Compression Tube Sleeve Viton Nptf

Product Description

The PARKER 60VLV-4 is a Viton compression tube sleeve designed for use in fluid and pneumatic line assemblies where reliable tube retention and leak-free performance are required. Built to the Vibra-Lok compression style, this sleeve grips the tube during assembly to resist vibration-induced loosening — a critical trait in mobile equipment and industrial piping applications. Rated for operating temperatures from -30 degrees F to 275 degrees F (135 degrees C), the Viton construction provides resistance to fuels, hydraulic fluids, and many aggressive media. It meets ISO 6149 and SAE J1926 standards. Licensed HVAC, plumbing, and fluid-power technicians are the typical installers.

The 60VLV-4 is suited for compression-style tube fittings in hydraulic, pneumatic, and fluid transfer lines found in industrial machinery, mobile equipment, and commercial mechanical systems. The NPTF thread standard makes it compatible with standard tapered pipe thread port connections common in North American equipment. Where vibration resistance is a priority — such as compressor discharge lines, engine compartment plumbing, or pump skid assemblies — the Vibra-Lok compression style provides added security over standard single-ferrule designs.

Key Features

• Vibra-Lok compression style resists loosening under vibration without requiring re-torque
• Operating range from -30 degrees F to 275 degrees F suits demanding thermal environments
• Meets ISO 6149 and SAE J1926 standards for port and fitting interchangeability
• NPTF thread standard for reliable tapered pipe thread port connections
• Sold as a single-piece unit, compatible with Parker compression fitting assemblies

Compatibility

Designed for use with Parker compression-style tube fittings utilizing the Vibra-Lok design and NPTF end connections conforming to ISO 6149 and SAE J1926 standards. No specific model numbers were provided in the product data; verify tube OD and fitting series before installation.

Installation Notes

Installation should be performed by a qualified fluid-power or mechanical technician familiar with compression fitting assembly procedures. Depressurize and de-energize the system fully before disassembling any tube connections. Ensure the tube end is cleanly cut, deburred, and properly inserted to the tube stop before tightening the compression nut. Follow the fitting manufacturer's assembly instructions for turn counts from finger-tight — do not over-tighten, as this can deform the sleeve and compromise the seal.
