Midland Industries 704050-0604 Flare Elbow Fitting

Product Description

The MIDLAND INDUSTRIES 704050-0604 is a lead-free brass SAE 45-degree flare female 90-degree elbow fitting designed to connect male flared tubing to female NPTF threaded pipe in a right-angle configuration. The fitting features a 3/8-inch male flared connection on one end and a 1/4-inch female NPTF connection on the other, with thread dimensions of 5/8-18 and 1/4-18 respectively. Constructed from lead-free brass, this elbow is rated for service from -40 to 250 degrees F and is suitable for fuel gas, refrigeration, and fluid systems requiring a reliable directional change. Licensed plumbers, HVAC technicians, and refrigeration mechanics install this type of fitting as part of line-set and supply-line assemblies.

This elbow fitting is suited for residential and light commercial plumbing, HVAC, and refrigeration applications where a compact 90-degree direction change is needed at a flared-to-NPT transition point. It is compatible with aluminum, brass, copper, or steel tubing conforming to SAE 45-degree flare standards. Its small overall dimensions make it appropriate for tight installations in equipment cabinets, appliance connections, and service panels where space is limited.

Key Features

• Lead-free brass construction meets lead-free compliance requirements for potable and non-potable fluid systems
• SAE 45-degree flare design provides a leak-resistant metal-to-metal seal at the flared connection
• Female NPTF thread on the second port ensures a pressure-tight mechanical seal without sealant tape alone
• Rated from -40 to 250 degrees F for broad service temperature compatibility
• Compatible with aluminum, brass, copper, or steel tubing for installation flexibility
• Compact footprint at 1.35 inches length and 0.8 inches height suits confined spaces

Compatibility

Designed for use with aluminum, brass, copper, or steel tubing conforming to SAE 45-degree flare standards, with a 3/8-inch male flared inlet and a 1/4-inch female NPTF outlet.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or refrigeration mechanic following applicable IPC and IFGC code requirements. Depressurize and isolate the system before disconnecting any fittings or tubing. Ensure the tubing end is properly flared to the SAE 45-degree specification before seating the flare nut to avoid leaks at the connection. Apply an appropriate thread sealant or PTFE tape to the NPTF threads per the system fluid requirements and manufacturer guidelines.
