Product Questions & Answers (1)

Question by: Jerry J on Jan 10, 2026, 5:27 PM
Does this fitting work for air brake lines, or is it meant for something else entirely?
Answer by: Customer Support on Jan 12, 2026, 7:21 AM
Air brake applications are exactly what the 479301 series is built around. The fitting connects to a 1/4-18 male NPT port on one end and accepts a -06 hose on the other, running straight through with no angle or elbow. The reusable design means you can pull it off the hose and put it back on without tossing the fitting every time, which adds up over the life of a rig or trailer.
