Parker 68CA-10-12 Compression Tube Connector 3/4-14 Nptf

Product Description

The PARKER 68CA-10-12 is a brass compression tube connector designed to join compression tubing to a male NPTF threaded port. It features a 3/4-14 thread size conforming to the NPTF standard, ensuring a pressure-tight mechanical seal without sealant tape on the threads. Rated for a maximum working pressure of 650 psi and a temperature range of -65 degrees F to 250 degrees F, this fitting handles demanding fluid and pneumatic service conditions. It is installed by licensed plumbers, pipefitters, and HVAC technicians working on tubing systems that require a reliable compression-to-NPT transition.

This connector is suited for residential and commercial applications where copper or compatible compression tubing must terminate at an NPTF male-threaded port. Typical install scenarios include refrigeration lines, hydraulic tubing runs, instrumentation connections, and general fluid transfer systems. Its brass construction resists corrosion in wet environments, making it appropriate for both above-ground plumbing and mechanical room installations where moisture exposure is common.

Key Features

• Brass construction provides corrosion resistance for wet and humid service environments
• 3/4-14 NPTF thread standard delivers a pressure-tight connection at the male NPT port
• Compression x MNPT end connections allow tubing-to-threaded-port transitions without additional adapters
• 650 psi maximum working pressure supports demanding fluid and pneumatic applications
• Wide temperature range of -65 degrees F to 250 degrees F suits a broad range of system conditions

Compatibility

Designed as an OEM-style replacement or service fitting for systems requiring a compression-to-MNPT connector with a 3/4-14 NPTF thread.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or HVAC technician. Shut off system pressure and depressurize the line completely before removing or installing any compression fitting. Compression fittings require proper tube preparation — ensure the tube end is cut square, deburred, and fully seated before tightening the compression nut. Follow applicable codes including IPC and IFGC for fluid system work, and verify the fitting material and pressure rating are appropriate for the specific fluid and operating conditions.
