Parker 68HD-10-8 Compression Tube Connector Brass

Product Description

The PARKER 68HD-10-8 is a brass compression tube connector designed to join compression-end tubing to male NPT threaded pipe or fittings. It provides a leak-resistant mechanical connection without soldering or flaring, making it a fast and reliable choice for plumbing, HVAC, and instrumentation lines. The fitting is constructed from brass and rated for a maximum working pressure of 1000 psi. End connections are compression on one side and male NPT on the other, with a 1/2-inch thread size. Licensed plumbers, HVAC technicians, and instrumentation mechanics are the typical installers of this fitting type.

This connector is suited for residential and light commercial applications where a tube-to-pipe transition is needed. Common install scenarios include connecting copper or compatible soft tubing to threaded valve bodies, manifolds, or equipment ports. The compression-by-MNPT configuration is frequently found in refrigeration lines, water supply connections, and pneumatic or hydraulic control circuits operating within the rated pressure range.

Key Features

• Brass construction provides corrosion resistance and durability in wet and pressurized service environments
• Compression x MNPT end connections allow tube-to-pipe transitions without soldering or flaring
• 1/2-inch thread size with MPT thread standard
• Rated to 1000 psi maximum working pressure
• Compact single-piece connector design for straightforward installation

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems requiring a 1/2-inch compression-to-male NPT transition in brass construction.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC or instrumentation technician in accordance with applicable local plumbing codes and ASME or ASTM standards for compression fittings. Shut off and depressurize the system fully before removing or installing any fittings. Use the correct tube size and ensure the tube end is cleanly cut and deburred before seating it into the compression fitting. Do not overtighten the compression nut, as excess force can deform the ferrule and compromise the seal.
