Question by: Janice G on Aug 10, 2025, 5:50 PM

does the brass construction on this hold up alright in corrosive environments, or is it gonna need extra protection?

Answer by: Customer Support on Aug 12, 2025, 6:42 AM

Brass naturally handles moisture and mild corrosion better than a lot of other metals, and this adapter also carries a Dura-Kote plating on top of that. That combination gives it solid resistance for hydraulic, pneumatic, and instrumentation setups where exposure to harsh conditions is a real concern.
