Midland Industries 2234X5 Inverted Male Connector Brass

Product Description

The MIDLAND INDUSTRIES 2234X5 is an SAE pattern inverted male connector designed for hydraulic and fluid-transfer line assemblies. It joins a 5/16-inch female inverted flare on one end to a 1/4-inch male NPTF thread on the other, providing a reliable leak-resistant transition between tubing and threaded port connections. Constructed from brass, this fitting is rated to 1200 psi and performs across a temperature range of -65 to 250 degrees F. It is installed by licensed plumbers, HVAC technicians, and hydraulic system technicians working on fluid control and refrigerant-adjacent tubing systems.

This connector is suited for use with copper, brass, aluminum, and steel hydraulic tubing in both residential and light commercial applications. The inverted flare design is common in brake lines, fuel lines, and hydraulic control circuits where a positive metal-to-metal seal is required. The NPTF male end creates a pressure-tight threaded connection without the need for additional sealant in properly machined ports.

Key Features

• SAE pattern inverted flare design provides a metal-to-metal seal on compatible tubing ends
• 5/16-inch female inverted flare x 1/4-inch male NPTF configuration for direct port-to-tube transitions
• Rated to 1200 psi for use in pressurized hydraulic and fluid-transfer systems
• Operating temperature range of -65 to 250 degrees F suits a wide range of service environments
• Brass construction resists corrosion and is compatible with copper, brass, aluminum, and steel tubing

Compatibility

Compatible with copper, brass, aluminum, and steel hydraulic tubing. Designed as an OEM-style SAE inverted flare fitting for hydraulic and fluid-transfer line assemblies requiring a 5/16-inch inverted flare to 1/4-inch NPTF male adapter.

Installation Notes

Depressurize and isolate the hydraulic or fluid circuit completely before removing or installing any fittings. Use a properly sized flaring tool to ensure the tubing end is formed to the correct SAE inverted flare angle before seating the fitting. NPTF threads are designed to seal on the threads themselves; inspect port threads for damage before installation. Follow applicable system codes and manufacturer torque guidance for brass fittings to avoid deforming the flare seat.
