Question by: Norm H on Sep 1, 2025, 3:11 PM
Reckon this'll work to step down a hydraulic line size on my tractor? Need to go from that bigger 1-5/16 size down to a 3/4.
Answer by: Customer Support on Sep 3, 2025, 6:23 AM
This adapter's made to do just that, connecting different-sized SAE O-ring boss ports. It's a straight adapter, so it'll keep your line running straight through.
