Parker VS68AB-10-6 Compression X Mnpt Brass Connector

Product Description

The PARKER VS68AB-10-6 is a brass compression tube connector designed to join a compression tube end to a male NPT pipe thread in fluid and pneumatic plumbing systems. Rated to 400 psi maximum working pressure and a temperature range of -65 degrees F to 250 degrees F, this fitting is built for reliable service in demanding environments. The 3/8-18 NPTF thread standard provides a pressure-tight mechanical seal without the need for additional sealant. With a 0.408 inch inside diameter, the fitting accommodates standard tubing sizes and is sold as a single unit. Licensed plumbers, HVAC technicians, and industrial maintenance professionals install this type of connector in hydraulic, pneumatic, and fluid-transfer lines.

This connector is suited for residential and light commercial plumbing, HVAC refrigerant or fluid piping, and industrial process lines where a compression-to-male NPT transition is required. The brass construction offers good corrosion resistance in water, air, and many hydraulic fluid applications. It is a common choice when connecting copper or compatible tubing to NPT-threaded equipment ports, valve bodies, or manifold connections in tight-space installations where a reliable mechanical grip fitting is preferred over soldered or push-to-connect alternatives.

Key Features

• 400 psi maximum working pressure for reliable service in pressurized systems
• Wide temperature range: -65 degrees F to 250 degrees F
• 3/8-18 NPTF thread standard ensures a pressure-tight mechanical seal
• Compression x MNPT end connections for tube-to-pipe-thread transitions
• Brass construction provides corrosion resistance in water, air, and hydraulic fluid service
• 0.408 inch inside diameter for standard tubing compatibility

Compatibility

Designed as an OEM-style replacement or new-installation compression-to-MNPT connector for use in plumbing, HVAC, and fluid-transfer systems requiring a 3/8-18 NPTF male pipe thread connection.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC or industrial technician familiar with compression fittings and NPT thread standards. Shut off and depressurize the system completely before disassembling or installing any fitting. NPTF threads are designed to seal on the threads themselves, but confirm system requirements before applying thread sealant. Do not overtighten the compression nut, as excessive force can deform the ferrule and compromise the seal.
