Parker 68CA-6-2 Compression Tube Connector 1/8-27 Mnpt

Product Description

The PARKER 68CA-6-2 is a brass compression tube connector designed to join tubing to male NPT threaded ports in fluid and gas distribution systems. It features a compression inlet and a 1/8-27 MNPT threaded outlet, conforming to NPTF thread standards for leak-resistant sealing without additional sealant tape in many applications. Rated to 1000 psi maximum working pressure, this connector handles a wide service temperature range from -65 degrees F to 250 degrees F. It is a single-piece fitting sold individually and suited for refrigeration, HVAC, pneumatic, and hydraulic plumbing applications where a reliable compression-to-NPT transition is required.

This connector is used wherever compression tubing must terminate at a male NPT threaded port. Typical applications include instrument lines, control tubing runs, refrigerant piping accessories, and low-to-medium pressure pneumatic circuits. It is installed by licensed HVAC technicians, plumbers, and instrumentation technicians working on both residential and light commercial equipment. The brass construction makes it compatible with a broad range of compatible media including air, water, oil, and many refrigerants at moderate temperatures and pressures.

Key Features

• Compression x MNPT end connections for direct tube-to-pipe-thread transition
• 1/8-27 thread size conforming to NPTF thread standard for secure, leak-resistant joints
• 1000 psi maximum working pressure rating
• Wide operating temperature range: -65 degrees F to 250 degrees F
• Brass construction for corrosion resistance and durability in fluid and gas service
• Single-piece fitting, sold individually

Compatibility

Designed as an OEM-style replacement or new-installation compression connector for systems requiring a 1/8-27 NPTF male threaded port connection with a compression tube inlet.

Installation Notes

Installation should be performed by a qualified HVAC technician, plumber, or instrumentation mechanic. Shut off all system pressure and isolate the line before disassembling or installing fittings. NPTF threads are designed for dry-seal engagement, but confirm compatibility with your system media and pressure rating before omitting thread sealant. Tighten compression fittings with appropriate tubing wrenches to avoid distorting the ferrule or fitting body.
