Air Hose & Couplings – Blue Dog Blasting carries several different sizes and versions for your needs. In this category, couplings include 2-lug and 4-lug style Chicago fittings. These are the quarter turn twist and lock fittings to connect air supplies. Whether you’re going straight from the compressor or between machines, these parts carry pressurized air without abrasives.

We also carry swivel ends to make pusher lines. This is the hose on the pot going from the air in side to the metering valve.
