Enlarger 1/2" - 3/8" (JG) – Push-Fit Tube Reducer

The John Guest 1/2" x 3/8" Grey Acetal Enlarger is a push-fit reducing connector designed to join 3/8" tubing to 1/2" tubing within drinks dispense and water systems. Manufactured from durable grey acetal, this fitting provides a reliable connection when transitioning between tubing sizes.

Featuring John Guest’s push-fit technology, tubing simply pushes into the fitting to create a secure seal without the need for tools or clamps. This allows quick installation and makes it easy to adapt systems where tubing sizes vary between components.

Enlarger fittings are widely used in beer dispense systems, beverage installations, water filtration equipment and drinks cooling systems, where tubing size changes are required between equipment.

What Is an Enlarger Connector Used For?

An enlarger connector allows tubing of different sizes to be joined together within a fluid or beverage system. This helps when equipment components use different tubing diameters but still need to connect within the same installation.

Push-fit enlarger fittings allow these transitions to be made quickly and securely without specialist tools.

Installation Tip

Always ensure tubing is cut cleanly before inserting it into the push-fit fitting. Push the tubing fully into the connector to ensure a proper seal.
