Parker VS68AB-12-12 Compression Tube Connector Brass

Product Description

The PARKER VS68AB-12-12 is a brass compression tube connector designed to join tubing to a male pipe thread port using a compression-style end connection. It features a 3/4-14 NPTF thread on the male NPT side and a compression fitting on the tube side, with an inside diameter of 0.533 inches. Rated for a maximum working pressure of 400 psi and a temperature range of -65 degrees F to 250 degrees F, this connector is built for reliable service in fluid and pneumatic plumbing lines. Plumbers, pipefitters, and mechanical contractors install this fitting in applications where a leak-free, vibration-resistant tube-to-pipe connection is required.

This compression connector is suited for use in residential and commercial plumbing, HVAC refrigerant line accessories, pneumatic systems, and hydraulic fluid distribution where tubing must terminate at a threaded port. The compression-style end eliminates the need for soldering or flaring at the tube side, making it a practical choice for retrofit and repair work. It is sold individually and is compatible with standard compression tubing sized to match the 0.533-inch inside diameter.

Key Features

• Brass construction for corrosion resistance and durability in fluid and pneumatic service
• Compression x MNPT end connections allow tube-to-pipe joining without soldering or flaring
• 3/4-14 NPTF thread standard for pressure-tight metal-to-metal sealing
• 400 psi maximum working pressure rating
• Wide temperature range: -65 degrees F to 250 degrees F
• Inside diameter of 0.533 inches for consistent flow path sizing

Compatibility

Designed as an OEM-style compression-to-MNPT connector for use in plumbing, HVAC, and pneumatic systems that require a 3/4-14 NPTF male pipe thread termination with a compression tube inlet.

Installation Notes

Installation is performed by licensed plumbers or qualified mechanical contractors. Shut off all fluid or air supply and relieve system pressure completely before removing or installing any fitting. Hand-tighten the compression nut onto the tubing, then advance with a wrench per standard compression fitting practice — do not overtighten, as brass threads and ferrules can deform. Verify thread engagement and system pressure integrity after installation before returning the system to service.
