Question by: Dwayne R on Sep 10, 2025, 12:03 PM
What's this fitting made out of, and is it gonna hold up in a tough industrial setup?
Answer by: Customer Support on Sep 12, 2025, 6:49 AM
Carbon steel construction on this one, which holds up well in demanding industrial environments. It's an Eaton Aeroquip piece, part of their 5400 series, so you're getting solid build quality that's meant for real-world use rather than light-duty situations.
