Parker VS68NTA-4-6 Compression Tube Connector 3/8 in

Product Description

The PARKER VS68NTA-4-6 is a brass compression tube connector designed to create a secure, leak-resistant joint between a compression fitting end and a male NPT threaded port. This straight connector is built for fluid and pneumatic line applications where a reliable mechanical seal is required without soldering or flaring. Rated to 150 psi maximum working pressure and a temperature range of -40 degrees F to 200 degrees F, it meets D.O.T. FMVSS571.106, SAE J1131, and SAE J246 standards. Licensed HVAC technicians, plumbers, and fluid-systems mechanics install this fitting during line assembly or service replacement in hydraulic, pneumatic, and compressed-air circuits.

This connector is suited for residential and light commercial fluid-handling systems where compression-to-MNPT transitions are required. Typical applications include compressed-air distribution lines, hydraulic control circuits, and fuel or brake line assemblies meeting D.O.T. and SAE specifications. The 3/8-inch thread size and NPTF thread standard make it a common choice for equipment requiring a pressure-tight threaded port connection on one end and a no-flare tube grip on the other. The fitting ships individually and is ready for single-point replacement or new installation.

Key Features

• Compression x MNPT end connections allow tube-to-threaded-port transitions without flaring or soldering
• Brass construction provides corrosion resistance and durability in fluid and pneumatic service
• Rated to 150 psi maximum working pressure for reliable performance in pressurized systems
• Wide operating temperature range of -40 degrees F to 200 degrees F suits varied service environments
• Meets D.O.T. FMVSS571.106, SAE J1131, and SAE J246 standards for regulated applications
• NPTF thread standard ensures a pressure-tight mechanical seal at the male NPT connection

Compatibility

Designed as an OEM-style replacement or new-installation fitting for compressed-air, hydraulic, and fluid-line systems requiring a 3/8-inch compression-to-MNPT straight connector meeting D.O.T. and SAE specifications.

Installation Notes

Installation should be performed by a licensed plumber, HVAC mechanic, or qualified fluid-systems technician. Depressurize and isolate the line completely before removing or installing any compression fitting. Apply thread sealant or PTFE tape to the MNPT threads in accordance with system requirements and applicable codes. Do not overtighten the compression nut; hand-snug plus the manufacturer-recommended turns is standard practice for compression fittings to avoid deforming the ferrule.
