Midland Industries FF1234M Flat Face Pipe Plug 1/2 in Npt

Product Description

The MIDLAND INDUSTRIES FF1234M is a flat face pipe plug designed to seal hydraulic lines and ports in high-pressure fluid systems. It features a 1/2-inch body size with a 3/4-inch female NPT connection and a flat face plug interface, making it suitable for use in hydraulic quick disconnect assemblies. Constructed from steel with a zinc-plated finish for corrosion resistance, this plug is rated for a maximum operating pressure of 4000 psi and a temperature range of -65 to 250 degrees F. It is installed by hydraulic system technicians and mechanics servicing mobile or industrial hydraulic equipment.

This plug fits applications in hydraulic quick disconnect systems where a flush or flat face seal is required to minimize fluid spillage during connection and disconnection. It is commonly used in industrial machinery, mobile equipment, and hydraulic power units where maintaining system cleanliness and preventing contamination is a priority. The female NPT thread provides a secure, leak-resistant port seal when the quick disconnect is not in use.

Installation Notes

Installation is performed by hydraulic technicians or qualified mechanics. Depressurize and bleed the hydraulic system completely before removing or installing any fittings or plugs. Use appropriate pipe thread sealant compatible with hydraulic fluid on NPT threads; do not overtighten threaded connections. Follow applicable industry standards and equipment manufacturer guidelines for hydraulic system service.
