Midland Industries 20515C Reducing Push-to-connect Union

Product Description

The MIDLAND INDUSTRIES 20515C is a reducing push-to-connect union designed to join two tubing lines of different outside diameters without tools. One end accepts 5/16-inch tubing and the other accepts 1/4-inch tubing, both using a push-to-connect mechanism for fast, secure connections. The composite body construction keeps weight low while providing solid performance in a range of fluid and pneumatic system applications. This fitting is rated to 150 psi and is suitable for service between 32 and 140 degrees F. It is typically installed by HVAC technicians, plumbers, and pneumatic system technicians working on low-pressure lines.

The 20515C is used in residential and light commercial applications where tubing of two different sizes must be joined in-line. Its compact profile makes it well suited for tight spaces inside equipment cabinets or behind panels. The push-to-connect design eliminates the need for compression ferrules, solder, or thread sealant at the connection points, reducing installation time on service calls and new installations alike.

Key Features

• Reduces from 5/16-inch push-to-connect to 1/4-inch push-to-connect in a single inline fitting
• Composite body construction for lightweight, corrosion-resistant performance
• Rated to 150 psi working pressure
• Operating temperature range of 32 to 140 degrees F
• Tool-free installation with push-to-connect ends on both sides
• Compact dimensions suited for tight equipment installations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for low-pressure tubing systems using 5/16-inch and 1/4-inch outside diameter tubing in residential and light commercial HVAC, plumbing, and pneumatic applications.

Installation Notes

Installation is performed by licensed HVAC technicians, plumbers, or qualified pneumatic system technicians. De-pressurize and isolate the line completely before disconnecting or installing any push-to-connect fitting. Ensure tubing ends are cut squarely and deburred before insertion to achieve a proper seal. Verify the installed assembly holds pressure before returning the system to service.
