Parker 68CA-5-2 Compression Tube Connector Brass Nptf

Product Description

The PARKER 68CA-5-2 is a brass compression tube connector designed to join compression-style tubing to a male national pipe thread (MNPT) fitting in fluid and pneumatic line assemblies. Rated to 1200 psi maximum working pressure and a temperature range of -65 degrees F to 250 degrees F, this connector handles demanding service conditions found in HVAC, refrigeration, and instrumentation applications. The NPTF thread standard provides a pressure-tight mechanical seal without relying solely on sealant tape. Licensed plumbers, HVAC technicians, and instrumentation fitters install this type of fitting when transitioning from compression tubing to threaded pipe connections.

This connector is suited for residential and light commercial systems where copper or compatible soft tubing terminates at a threaded port on a valve, manifold, gauge, or equipment fitting. The compression-by-MNPT configuration makes it a common choice on refrigerant sensing lines, pneumatic control circuits, and water supply connections where a reliable, vibration-resistant joint is required without soldering or brazing.

Key Features

• 1200 psi maximum working pressure for high-demand fluid and pneumatic service
• Operating temperature range of -65 degrees F to 250 degrees F
• NPTF thread standard for a pressure-tight seal at the male NPT end
• Compression x MNPT end configuration for tool-free tubing termination on one end
• Brass construction for corrosion resistance and durability in wet or refrigerant-adjacent environments

Compatibility

Designed as an OEM-style replacement or direct-install compression tube connector for systems requiring a 1/8-27 NPTF male threaded port transition with a compression tubing inlet.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or instrumentation fitter. Shut off all system pressure and depressurize the line before disassembly or fitting installation. NPTF threads are designed to seal on thread engagement, but many installers apply thread sealant compatible with the system fluid as an added precaution. Do not overtighten the compression nut, as brass fittings can crack under excessive torque.
