does this fitting need a mandrel to crimp on, or can i just run it straight through the crimper?
Answer by: Customer Support on Oct 10, 2025, 3:23 PM
No mandrel required for installation. You can run it straight through your crimper without any additional tooling for that step. It's built to work with -04 hose and pairs with H277 or H435 hose where shock hazards are a concern.

Will this fitting hold up okay for general hydraulic use on my tractor?

It's made for general-purpose low and medium-pressure hydraulic systems, and it’s often used where there could be some shock. So, yeah, it should do the trick.
