Parker 61VL-2 Compression Tube Nut Brass Nptf 3/8-24

Product Description

The PARKER 61VL-2 is a brass compression tube nut designed for use in hydraulic and fluid system assemblies. It features a Vibra-Lok compression style that resists loosening under vibration, making it well suited for mobile equipment, industrial machinery, and HVAC refrigerant or fluid lines. The nut conforms to ISO 6149 and SAE J1926 standards and carries a 3/8-24 straight thread size. With a temperature range of -30 degrees F to 275 degrees F, it handles a wide range of operating environments. Licensed technicians and pipefitters install this fitting where a reliable, leak-resistant compression connection is required on tubing runs.

This compression tube nut is used in residential and commercial fluid handling systems, hydraulic circuits, and equipment plumbing where NPTF-standard threaded connections are specified. The Vibra-Lok compression style is particularly applicable in installations subject to continuous vibration, such as compressor discharge lines, mobile hydraulic systems, and refrigeration tubing assemblies. It is sold and installed as a single unit and is sized for 3/8-24 straight thread applications.

Key Features

• Vibra-Lok compression style resists loosening under sustained vibration
• Brass construction provides corrosion resistance in fluid and refrigerant service
• Meets ISO 6149 and SAE J1926 standards for dimensional and performance consistency
• 3/8-24 straight thread size for precise, repeatable thread engagement
• Rated for service from -30 degrees F to 275 degrees F
• NPTF thread standard ensures pressure-tight connections without additional sealant in many applications

Compatibility

Designed as an OEM-style compression tube nut for fluid system assemblies requiring NPTF 3/8-24 straight thread connections conforming to ISO 6149 and SAE J1926 standards.

Installation Notes

Installation should be performed by a qualified technician familiar with fluid system plumbing and applicable codes. De-pressurize and isolate the fluid circuit completely before removing or installing any fittings. Use appropriate tubing cutters and deburring tools to prepare tubing ends before seating the compression nut. Do not overtighten; follow the fitting manufacturer's standard assembly procedure for compression-style connections.
