putting together an air brake harness on a trailer, is this 3270 tubing meant for that kind of setup?

For truck and trailer air brake systems, it’s commonly used in formed tubes and in both formed and straight air brake harness assemblies, plus auxiliary air systems.

what fittings work with this tubing? got a trailer harness job coming up and want to make sure i grab the right connectors
Answer by: Customer Support on Jun 8, 2025, 6:29 AM
QCAB fittings and push-to-connect fittings are the qualified options for this tubing. Both are compatible with the 3270 series, so either will work depending on how your harness assembly is set up. Just make sure you're matching to the dash 12 size and you'll be good to go.
