Question by: Dale O on Nov 14, 2025, 6:58 PM
Is this fitting okay for hooking up the air brakes on my old farm truck?
Answer by: Customer Support on Nov 15, 2025, 8:55 PM
It's designed for air brake systems, so yeah, it should work fine for your farm truck as long as the temperature around the fitting stays below 200°F. Just make sure no battery acid can drip on the tubing.
