Midland Industries 20514N Stem Reducer 1/2 X 3/8 in Np Brass

Product Description

The MIDLAND INDUSTRIES 20514N is a nickel-plated brass stem reducer designed to transition between a 1/2-inch plug-in stem connection and a 3/8-inch push-to-connect port. It is rated for 290 psi and handles temperatures from -4 degrees F to 176 degrees F, making it suitable for a range of fluid and gas distribution applications. At 1.693 inches in length, this compact fitting installs quickly without tools on the push-to-connect side, reducing labor time during assembly or service. Plumbers, HVAC technicians, and refrigeration installers commonly use this type of reducer when connecting tubing of differing diameters in tight spaces.

This stem reducer fits into residential and light commercial plumbing and HVAC distribution systems where a plug-in stem port must be paired with a smaller 3/8-inch push-to-connect line. Typical applications include ice maker supply lines, refrigeration tubing runs, HVAC hydronic systems, and compressed air distribution. The push-to-connect end accepts tubing insertion without additional fittings or sealant, and the plug-in stem end seats securely into compatible valve bodies or manifold ports. This fitting is part of Midland Industries push-to-connect nickel-plated brass product line.

Key Features

• Reduces from 1/2-inch plug-in stem to 3/8-inch push-to-connect in a single fitting
• Nickel-plated brass construction resists corrosion and withstands moderate pressure service
• Rated to 290 psi for use in pressurized fluid and gas lines
• Operating temperature range of -4 degrees F to 176 degrees F suits most HVAC and plumbing environments
• Compact body at 1.693 inches long fits in confined installation spaces
• Push-to-connect end allows tool-free tubing insertion for faster assembly

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 1/2-inch plug-in stem valve ports paired with 3/8-inch push-to-connect tubing lines in plumbing, HVAC, and refrigeration applications.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Depressurize and isolate the line before removing or installing any fitting. Ensure the tubing end is cut square, deburred, and fully inserted into the push-to-connect port until it seats against the internal stop. Verify the plug-in stem end is fully engaged and locked into the mating valve or manifold body before restoring system pressure.
