Question by: Rhonda T on Mar 24, 2026, 9:17 PM
Will this fitting hold up okay on a refrigeration system in a semi-truck? Seems like those get beat up pretty good.
Answer by: Customer Support on Mar 26, 2026, 5:12 PM
It's definitely suitable for heavy-duty truck use, along with industrial and automotive applications. The Dura-Kote plating on the carbon steel is made to give it superior corrosion resistance, which should help it last.
