Midland Industries PSP-417 Sae 45 Deg Flare Nut 3/8 in

Product Description

The MIDLAND INDUSTRIES PSP-417 is a short forged SAE 45-degree flare nut designed for use in flared tubing connections across HVAC, refrigeration, and plumbing systems. Machined from C3604 brass, this fitting provides a reliable, leak-resistant connection at a 3/8-inch flared interface. The 45-degree flare profile conforms to SAE flare standards, making it a direct-fit component for systems that require a secure mechanical joint without the use of solder or additional sealant. Suitable for residential and light commercial applications, the PSP-417 is a stock item for techs who regularly work with flared copper or brass tubing lines.

This flare nut is used wherever a 3/8-inch SAE 45-degree flared connection is required. Common applications include refrigerant line sets, fuel gas distribution lines, and hydraulic or pneumatic tubing assemblies. The short forged nut profile is suited for tight-clearance installations where a standard-length nut may not fit. HVAC technicians, plumbers, and gas fitters routinely stock this fitting for service calls and new installations involving flared tube ends.

Key Features

• SAE 45-degree flare geometry for leak-resistant mechanical tube connections
• Short forged nut design for use in limited-clearance installations
• C3604 brass construction resists corrosion in gas, refrigerant, and fluid service
• 3/8-inch flared connection size matches standard copper and brass tubing
• No solder or thread sealant required when properly flared and torqued

Compatibility

Designed as an OEM-style replacement or service fitting for systems using SAE 45-degree flared tube connections at 3/8-inch tubing size.

Installation Notes

Installation should be performed by a qualified HVAC technician, plumber, or gas fitter in accordance with applicable codes including IFGC and IPC. Always depressurize and isolate the line before removing or installing flare fittings. Ensure the tube end is properly flared using a calibrated 45-degree flare tool before seating the nut. Do not over-tighten, as brass flare fittings can crack or deform the flare seat if excessive force is applied.
