Question by: Lynn C on Jan 18, 2026, 1:34 PM
what's this adapter made out of, and will it hold up running hydraulic lines regular?
Answer by: Customer Support on Jan 20, 2026, 6:21 AM
Brass construction throughout, and it carries Dura-Kote plating on top of that for added corrosion resistance. For hydraulic, pneumatic, and instrumentation lines, it's built to handle the job. The plating is specifically there to give it longer service life in conditions where bare brass might start to show wear over time.
