Parker 60VL-4 Compression Tube Sleeve Buna-n Nptf

Product Description

The PARKER 60VL-4 is a compression tube sleeve designed for use in hydraulic and pneumatic fluid-conveyance assemblies. This sleeve functions as the gripping component in a compression fitting, creating a leak-resistant seal by deforming around the tube when the fitting nut is tightened. Constructed from Buna-N elastomer, it resists petroleum-based fluids and maintains integrity across a temperature range of -30 degrees F to 275 degrees F. It meets ISO 6149 and SAE J1926 standards and uses Parker's Vibra-Lok compression style for reliable vibration-resistant connections. Licensed HVAC technicians, plumbers, and fluid-power mechanics install this sleeve as part of complete compression fitting assemblies.

This sleeve is suited for residential and light commercial fluid-power and plumbing applications where compression-style fittings are specified. It is intended for use with NPTF-threaded compression fitting bodies and matching nuts. The Vibra-Lok design makes it appropriate for installations subject to vibration or intermittent pressure cycling, such as equipment-mounted lines, refrigeration interconnects, and hydraulic service circuits. The Buna-N material is compatible with petroleum oils, water, and many common hydraulic fluids encountered in trade service work.

Key Features

• Buna-N construction provides resistance to petroleum-based fluids and hydraulic oils
• Vibra-Lok compression style resists loosening under vibration and pressure cycling
• Meets ISO 6149 and SAE J1926 standards for consistent, interchangeable fitment
• NPTF thread standard for reliable pressure-tight connections
• Operating range of -30 degrees F to 275 degrees F suits a wide range of service environments
• Sold as a single-piece unit with a minimum order quantity of one

Compatibility

Designed for use with compression fitting assemblies conforming to ISO 6149 and SAE J1926 standards with NPTF thread connections. Specific compatible fitting bodies or tube sizes were not detailed in available product data; verify tube outside diameter and fitting series before ordering.

Installation Notes

Installation is performed by qualified plumbers or fluid-power mechanics working on pressurized lines. Depressurize and drain the affected line completely before disassembling any fitting. Do not reuse a previously compressed sleeve, as deformation from initial installation compromises the seal on reinstallation. Follow applicable IPC or equipment manufacturer torque and assembly procedures when making up compression connections.
