Midland Industries 04093-08100812 Brass Sae 45 Deg Cross

Product Description

The MIDLAND INDUSTRIES 04093-08100812 is a four-way brass cross fitting designed for SAE 45-degree flare and female NPT connections. It provides a single intersection point for multi-line refrigerant, fuel gas, or hydraulic systems where three flared male connections and one female NPT port are required. Port 1 accepts a 1/2-inch male flare, Port 2 accepts a 5/8-inch male flare, Port 3 accepts a 1/2-inch male flare, and Port 4 accepts a 3/4-inch female NPT connection. Constructed entirely from brass, this cross fitting resists corrosion and is well suited for use in HVAC refrigerant circuits, propane or natural gas distribution, and related fluid systems. Licensed HVAC technicians and plumbers are the primary installers of this fitting type.

This cross fitting is used in residential and light commercial applications where a single manifold point must branch flow to three separate lines. Its SAE 45-degree flare geometry makes it compatible with standard flare-nut tubing assemblies. The mixed port sizing allows it to serve multi-diameter line sets or fuel distribution circuits. Typical installation scenarios include refrigerant manifold assemblies, LP or natural gas distribution headers, and related piping systems requiring a four-connection cross configuration.

Key Features

• Four-way cross configuration with three male flare ports and one female NPT port
• SAE 45-degree flare geometry on all three male flare connections
• Mixed port sizing: 1/2 in, 5/8 in, 1/2 in male flare and 3/4 in female NPT
• All-brass construction for corrosion resistance and durability
• Designed for use in refrigerant, fuel gas, and hydraulic fluid systems

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using SAE 45-degree flare connections combined with standard female NPT porting. Compatible with standard 1/2-inch and 5/8-inch flare-nut tubing assemblies and 3/4-inch female NPT piping.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber following applicable codes such as the International Fuel Gas Code or NEC where relevant. Always isolate and depressurize the system before disassembling or threading any fittings. SAE 45-degree flare connections should be made with a calibrated flaring tool to ensure a proper seal; do not overtighten flare nuts. Female NPT connections should be made with appropriate thread sealant rated for the system media - verify compatibility with refrigerant or gas service before applying any compound.
