Question by: Marvin C on Feb 4, 2026, 1:09 PM
So, this here is carbon steel, right? Wondering how it holds up outside.
Answer by: Customer Support on Feb 6, 2026, 6:28 AM
Carbon steel construction gives it good strength for hydraulic applications, and Waltech fittings include corrosion protection. That should help extend service life, even if you have it out in the elements.
