Parker 159F-12-8 Brass 45 Elbow 3/4 in Tube Od 1/2-14 Nptf

Product Description

The PARKER 159F-12-8 is a brass 45-degree male elbow fitting designed to connect a flared tube to a male NPTF threaded port. It accepts a 3/4-inch tube OD on the flare end and terminates in a 1/2-14 NPTF male thread on the pipe end. The 45-degree angle allows directional routing of tubing in tight or angled installations where a straight fitting would not clear adjacent components. This fitting is commonly installed by HVAC technicians, refrigeration mechanics, and plumbers working with flared copper or aluminum tubing in fluid and gas line assemblies. The brass construction provides good corrosion resistance and machinability across a wide range of service conditions.

This fitting is suited for residential and light commercial HVAC, refrigeration, and plumbing applications where a flared tube must transition to a NPTF-threaded port at a 45-degree offset. Typical use cases include connecting refrigerant lines, fuel oil lines, or hydraulic tubing to manifolds, valves, or equipment ports. The Flare x MNPTF end configuration makes it a straightforward solution when the system requires a reliable metal-to-metal flare seal on one side and a tapered pipe thread seal on the other.

Key Features

• 45-degree elbow geometry for angled tube routing in confined spaces
• Flare x MNPTF end connections provide a leak-resistant metal-to-metal seal on the flare side
• 3/4-inch tube OD flare end compatible with standard SAE 45-degree flare tooling
• 1/2-14 NPTF male thread for secure tapered pipe thread engagement
• Brass material offers corrosion resistance suitable for refrigerant, fuel, and water service

Compatibility

Designed as a standard SAE 45-degree flare fitting for use in systems requiring a 3/4-inch tube OD flare connection mated to a 1/2-14 NPTF male threaded port. Verify system pressure ratings, fluid compatibility, and thread engagement requirements before installation.

Installation Notes

Installation is performed by qualified HVAC technicians, refrigeration mechanics, or licensed plumbers. Depressurize and isolate the line before disassembling any fitting. Use proper SAE 45-degree flaring tools to prepare the tube end; do not substitute 37-degree flare tooling. Apply a compatible thread sealant to the NPTF male threads as required by the applicable code or equipment manufacturer guidelines, and torque fittings using calibrated wrenches rather than over-tightening by feel.
