Parker 68CA-16-16 Compression Tube Connector 1 in Od

Product Description

The PARKER 68CA-16-16 is a brass compression tube connector designed to join 1-inch OD tubing to a male NPT threaded port. The compression end grips the tube mechanically without soldering or flaring, creating a leak-resistant seal rated to 350 psi maximum working pressure. The MNPT end threads into standard NPT female ports at a 1-11/2 inch thread size. Brass construction offers corrosion resistance and compatibility with a wide range of fluids and gases. This fitting is installed by HVAC technicians, plumbers, and pipefitters working on refrigeration, fluid transfer, and general instrumentation systems.

This connector is suited for residential and light commercial applications where copper or compatible tubing meets a threaded component such as a valve, manifold, or equipment port. Typical uses include refrigeration lines, compressed air distribution, hydraulic instrument connections, and potable water systems where the operating temperature stays within the rated range of -65 degrees F to 250 degrees F. The single-piece connector body keeps installation simple and keeps the fitting count low at transition points.

Key Features

• Brass construction for corrosion resistance and broad fluid compatibility
• Compression end accommodates 1-inch OD tubing with no soldering or flaring required
• MNPT end joins standard female NPT ports at 1-11/2 inch thread size
• Rated to 350 psi maximum working pressure
• Wide temperature range: -65 degrees F to 250 degrees F
• Single-piece body minimizes potential leak points at tube-to-thread transitions

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 1-inch OD compression tubing with a 1-11/2 inch MNPT threaded connection point in HVAC, plumbing, refrigeration, and instrumentation applications.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or pipefitter. Depressurize and isolate the line before disassembly or fitting installation. Verify that tubing OD is clean, round, and free of burrs before inserting into the compression end, and tighten the compression nut to hand-tight plus the manufacturer-recommended turns without over-torquing the brass body. Follow applicable IPC or IFGC requirements for the system type and local jurisdiction.
