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

Product Description

The PARKER VS68NTA-6-6 is a brass compression tube connector designed to create a secure, leak-resistant joint between a compression tube end and a male NPT threaded port. Rated to 150 psi maximum working pressure and suitable for temperatures from -40 degrees F to 200 degrees F, this fitting handles demanding fluid and pneumatic line applications. Manufactured to D.O.T. FMVSS571.106, SAE J1131, and SAE J246 standards, it meets the certification requirements found in mobile, hydraulic, and general plumbing installations. The NPTF thread standard ensures a pressure-tight mechanical seal without the need for sealant tape on every application.

This connector is used in residential and commercial fluid distribution systems, pneumatic lines, and mobile equipment plumbing where a 3/8 inch OD tube must terminate at an NPT threaded port. Typical installation scenarios include HVAC refrigerant or control-line connections, compressed air distribution, fuel and hydraulic circuits, and trailer brake line assemblies where D.O.T. compliance is required. The brass construction suits potable water, oil, and moderate-pressure gas service in environments within the rated temperature range.

Key Features

• Brass body resists corrosion in water, oil, and light fuel service
• Compression x MNPT end connections for tool-assisted, tube-to-thread joints
• Rated to 150 psi maximum working pressure
• Temperature range of -40 degrees F to 200 degrees F
• Meets D.O.T. FMVSS571.106, SAE J1131, and SAE J246 standards
• NPTF thread standard for a pressure-tight mechanical seal

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 3/8 inch OD compression tubing with a male NPT threaded port connection.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or mobile equipment mechanics. Shut off and depressurize the line completely before disassembling any existing fittings. Hand-tighten the compression nut before applying a wrench to avoid cross-threading; do not overtighten, as brass compression fittings can crack or deform the ferrule. Follow applicable IPC, IFGC, or NEC requirements for the specific fluid service and jurisdiction.
