Midland Industries 7045820 1/2 in Nptf X M20 Metric Adapter

Product Description

The MIDLAND INDUSTRIES 7045820 is a steel hydraulic adapter designed to connect 1/2-inch Female NPTF ports to M20 Male Metric fittings. Part of the 7045 Series, it bridges NPTF and metric thread standards in a single compact body. The M20 x 1.5 thread pitch and NPTF sealing design provide a pressure-resistant, leak-minimizing connection suitable for hydraulic lines operating up to 375 degrees F. This fitting is installed by hydraulic technicians, maintenance mechanics, and plumbers working on equipment that mixes inch and metric port standards.

This adapter is used in hydraulic systems where metric-ported components such as cylinders, valves, or manifolds must connect to NPT-threaded lines or fittings. Common applications include mobile hydraulic equipment, industrial machinery, and fluid power assemblies that integrate both metric and inch-standard components. Its steel construction makes it appropriate for high-pressure, high-temperature hydraulic circuits where brass or aluminum fittings would be inadequate.

Key Features

• Connects 1/2-inch Female NPTF to M20 x 1.5 Male Metric thread in a single fitting
• Rated for operating temperatures up to 375 degrees F
• Steel construction for durability in high-pressure hydraulic service
• NPTF thread form provides interference-seal fit without sealant tape on the female side
• Compact profile at 1.6 inches length and 1.3 inches width for use in tight installations
• Part of the 7045 Series Steel Metric Adapters line

Compatibility

Designed as an OEM-style hydraulic adapter for fluid power and hydraulic systems requiring a 1/2-inch NPTF female port to M20 male metric thread connection.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. NPTF threads are designed to seal on the thread form itself, but confirm port compatibility and inspect threads for damage before assembly. Torque to the equipment manufacturer's specified value for the port size and material.
