Heat is a byproduct of mechanical energy that presents itself as a temperature increase. French physicist James Prescott Joule aimed to equate heat to mechanical energy. Early experiments used paddle-like structures to stir water within a container and raise its temperature. The paddles would move and agitate the water whenever a mass on a pulley […]

Technicians have to make flare fittings in the field every day. Most of the time, the application is for mini-split/ductless installs. However, you may encounter certain situations where flared fittings are more practical than a braze joint. Regardless of the reason, flared connections are notorious in our trade for being popular leak areas.
