Parker 68HD-4-8 Compression X Mnpt Brass Connector 1/2 in

Product Description

The PARKER 68HD-4-8 is a heavy-duty brass compression tube connector designed to create a secure, leak-resistant joint between a compression tube end and a male NPT threaded pipe or fitting. Built from solid brass, this connector handles working pressures up to 2100 psi, making it well suited for demanding fluid and gas distribution systems. The 1/2 inch thread size accommodates common tubing runs found in HVAC, plumbing, and industrial fluid-handling applications. Licensed plumbers, HVAC technicians, and pipefitters install this type of fitting as part of new construction or repair work where a reliable tube-to-pipe transition is required.

The PARKER 68HD-4-8 is used in residential and commercial systems wherever a compression-to-male NPT connection is needed. Typical applications include refrigerant-adjacent tubing assemblies, instrumentation lines, hydraulic pilot lines, and general plumbing supply runs. The compression end accepts tubing without requiring soldering or flaring, while the MNPT end threads directly into a pipe fitting, valve, or manifold port.

Key Features

• Brass construction provides corrosion resistance and durability in wet or chemically active environments
• 2100 psi maximum working pressure supports high-demand fluid and gas service
• Compression x MNPT end connections allow tube-to-threaded-pipe transitions without soldering or flaring
• 1/2 inch thread size fits standard NPT pipe threads and matching compression tubing
• Sold individually, making it practical for single-unit repairs or small-quantity installations

Compatibility

Designed as an OEM-style replacement or new-install compression tube connector for systems using 1/2 inch male NPT threaded ports and compatible compression tubing in HVAC, plumbing, and fluid-handling applications.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified pipefitter following applicable IPC and local plumbing code requirements. Shut off the fluid or gas supply and relieve system pressure completely before removing any existing fitting or installing this connector. Apply thread sealant or PTFE tape to the MNPT threads per standard practice, and tighten the compression nut to manufacturer-recommended hand-tight-plus turns without over-torquing the brass ferrule. Inspect for leaks after restoring system pressure before returning the system to service.
