Parker 68VL-12-12 Compression Tube Connector 3/4-14 Mnpt

Product Description

The PARKER 68VL-12-12 is a brass compression tube connector designed to create a secure, leak-resistant junction between compression tubing and a male NPT port. It features Parker's Vibra-Lok compression style, which provides reliable tube retention in applications subject to vibration and pressure cycling. The fitting is rated to 100 psi maximum working pressure and handles a temperature range of -30 degrees F to 275 degrees F. Constructed from brass, it offers solid corrosion resistance in fluid and pneumatic plumbing systems. This connector is appropriate for installation by licensed plumbers, HVAC technicians, and industrial maintenance professionals working on tubing assemblies.

This fitting is suited for use in hydraulic, pneumatic, and fluid transfer systems where a compression-to-male NPT transition is required. The 3/4-14 thread size is a common NPT port size found in manifolds, valves, and equipment panels in both commercial and industrial environments. The Vibra-Lok compression design eliminates the need for flaring or soldering, making it a practical choice for field installations and equipment retrofits where torch work is not feasible or permitted.

Key Features

• Vibra-Lok compression style for vibration-resistant, no-flare tube retention
• Brass construction for corrosion resistance in fluid and pneumatic service
• 3/4-14 male NPT end connection for standard port compatibility
• Rated to 100 psi maximum working pressure
• Meets ISO 6149 and SAE J1926 standards
• Operating range of -30 degrees F to 275 degrees F

Compatibility

Designed as an OEM-style compression-to-MNPT connector for hydraulic, pneumatic, and fluid transfer plumbing systems requiring a 3/4-14 NPT port connection.

Installation Notes

Installation should be performed by a qualified plumber or hydraulic technician familiar with compression fitting assembly procedures. Depressurize and isolate the system completely before removing or installing any fittings. Do not overtighten the compression nut, as brass fittings can deform the ferrule and cause leaks. Verify thread engagement and ferrule seating before returning the system to service.
