John Guest 3/8″ to 5/16″ Stem Reducer – Push-Fit Adaptor

The John Guest 3/8″ to 5/16″ Stem Reducer is a push-fit adaptor used to reduce a compatible 3/8″ push-fit connection to 5/16″ OD pipe. It is commonly used in draught beer, beverage and gas dispense systems where two different connection sizes need to be joined.

The 3/8″ stem inserts directly into a compatible 3/8″ push-fit socket, leaving a 5/16″ push-fit connection for the smaller pipe.

3/8″ Stem to 5/16″ Push-Fit

This type of reducer is useful when adapting existing 3/8″ fittings or equipment connections to smaller 5/16″ OD beverage or gas pipe without replacing the original fitting.
