Parker 68HD-6-2 Compression Tube Connector 3/8 in Brass

Product Description

The PARKER 68HD-6-2 is a brass compression tube connector designed to join 3/8 inch OD tubing to a male NPT threaded port. It provides a secure, leak-resistant mechanical connection without soldering or brazing. The fitting uses a compression sleeve and nut to grip the tube OD, making it well suited for hydraulic, pneumatic, and fluid transfer lines where a reliable threaded port connection is required. Rated to 1500 psi maximum working pressure, this connector handles demanding pressure applications across a wide temperature range of -65 degrees F to 249 degrees F. Plumbers, HVAC technicians, and fluid system installers use this type of fitting regularly in both residential and light commercial installations.

This fitting is appropriate for use in refrigeration tubing, hydraulic control lines, pneumatic instrumentation, and general fluid transfer systems where 3/8 inch OD compression tubing terminates at a male NPT threaded port. Its brass construction makes it compatible with a variety of media including water, air, oil, and many hydraulic fluids. It is sold individually and is suitable for trade service work requiring a single replacement or new installation fitting.

• Compact, lightweight design at 0.08 pounds for easy handling in tight spaces

Compatibility

Designed as an OEM-style compression fitting for use with 3/8 inch OD tubing and male NPT threaded ports in hydraulic, pneumatic, refrigeration, and general fluid transfer assemblies.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or fluid systems mechanic. Depressurize and isolate the line completely before removing or installing any compression fitting. Ensure the tube end is cut squarely and deburred before inserting into the compression sleeve to achieve a proper seal. Refer to applicable codes such as the IPC or IFGC as appropriate for the system type and media being used.
