John Guest first started in 1961 making various custom parts for multiple industries like automotive. In 1974 they created the Speedfit connection. This innovation allowed you connect plumbing fittings together easily by pushing them into each other without the need for tools or seals. Today you will find John Guest parts in many different types of equipment such as ice makers, soda machines, refrigerators, and espresso machines. Back in 2014 we were looking for an easy way for our customers to connect their espresso machines to a direct water line. That's when we found John Guest and started bringing in a variety of their push fitting parts.
