Parker 46F-8-12 Brass Flared Tube Connector 1/2 in

Product Description

The PARKER 46F-8-12 is a brass flared tube connector designed for secure, leak-resistant tube-to-pipe connections in fluid and gas distribution systems. It features a 45-degree flare angle with a Flare x FNPTF end configuration, accepting a 1/2-inch tube OD on the flare end and a 3/4-14 NPTF female thread on the pipe end. The NPTF thread form creates a pressure-tight mechanical seal without relying solely on sealant tape. Plumbers, HVAC technicians, and refrigeration mechanics install this fitting where copper or compatible tubing must transition to a threaded pipe connection in tight, high-reliability applications.

This connector is suited for residential and light commercial plumbing, refrigeration lines, fuel systems, and hydraulic tubing runs where a 45-degree flared tube end meets a female national pipe taper fuel thread port. The Flare x FNPTF configuration makes it a common choice for transitions between soft copper tubing and threaded pipe bodies, valves, or manifolds. Typical installations include fuel gas distribution, refrigerant line sets, and hydraulic control circuits.

Key Features

• 45-degree flare angle for positive, leak-resistant tube seating
• Flare x FNPTF end connection for tube-to-pipe-thread transitions
• 3/4-14 NPTF thread provides a dry-seal mechanical fit
• 1/2-inch tube OD compatibility for standard copper and compatible tubing
• Brass construction offers corrosion resistance and reliable torque response

Compatibility

Designed as an OEM-style replacement or service fitting for systems using 1/2-inch OD flared tubing with a 3/4-14 NPTF female threaded port connection.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or refrigeration mechanic following applicable local codes and IFGC or IPC guidelines where relevant. Shut off system pressure and depressurize the line before disassembly or fitting installation. Ensure the tube end is properly flared to 45 degrees with a calibrated flaring tool before seating the connector. NPTF threads are designed for dry-seal assembly, but consult applicable code for any sealant requirements in your jurisdiction.
