Question by: Harvey C on Sep 28, 2025, 8:39 PM
Running this on a piece of ag equipment that sees everything from late-season mud to chemical exposure. The brass hold up alright in those conditions, or is that gonna be a weak point?
Answer by: Customer Support on Sep 30, 2025, 6:09 AM
Brass construction paired with stainless steel springs gives this coupling solid corrosion resistance across a wide range of fluids and environments. For straight hydraulic and general fluid transfer work in ag settings, it holds up well. If you're running it in contact with more aggressive chemicals regularly, the seal material is worth paying attention to. Standard seals are Buna-N, but you can spec it with Neoprene, FKM, EPDM, or Kalrez if the fluid compatibility requires something different.
