Midland Industries FF12M Flat Face Pipe Plug 1/2 in Npt Steel

Product Description

The MIDLAND INDUSTRIES FF12M is a flat face pipe plug designed for hydraulic systems requiring a secure, leak-resistant seal at a 1/2-inch body connection. Constructed from steel with a zinc-plated finish, this plug handles demanding service conditions with a maximum operating pressure of 4000 psi and a working temperature range of -65 to 250 degrees F. The flat face design minimizes fluid spillage and air inclusion during disconnection, making it the preferred choice for clean hydraulic circuits. Licensed technicians and hydraulic system specialists are the primary installers.

The FF12M is suited for use in residential and commercial hydraulic applications where a reliable shutoff or port plug is needed. Its 1/2-14 NPT female thread connection makes it compatible with standard hydraulic manifolds, cylinders, valve bodies, and plumbing circuits. The flat face profile is especially appropriate in systems where contamination control and minimal fluid loss are priorities, such as mobile equipment, industrial machinery, and hydraulic power units.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize and isolate the hydraulic circuit fully before removing or installing any plug or fitting. Use appropriate thread sealant compatible with hydraulic fluid and verify thread engagement before returning the system to pressure. Torque to the fitting manufacturer specifications and inspect for leaks after system restart.
