Question by: Kurt O on Sep 25, 2025, 6:43 PM
Reckon this would work okay for hooking up to my tractor's hydraulic lines for running attachments?
Answer by: Customer Support on Sep 27, 2025, 7:22 AM
This coupling is designed for on-highway hydraulic wet lines, which means it should be compatible with your tractor's hydraulic system, assuming the SAE fitting matches. Just double-check your system's flow rate and pressure to make sure they align with this coupling's specs.
