Question by: Daryl G on Oct 5, 2025, 9:54 PM

Hey, will this hose hold up okay if it's dragging on the ground some? Just wondering how tough that outer layer is.

Answer by: Customer Support on Oct 7, 2025, 9:20 AM

The chloroprene rubber cover offers standard abrasion resistance, which should provide decent protection in ground contact situations, but avoiding constant dragging will extend its life.
