Question by: Dean A on Feb 5, 2026, 8:25 PM
running a dump trailer with a 1-inch wet line setup, will this coupling handle the flow without choking things down?
Answer by: Customer Support on Feb 7, 2026, 6:45 AM
Forty gallons per minute is what this coupling is rated for at that port size, so for a standard dump trailer wet line application, you've got plenty of capacity. The 1-inch thread-to-connect body pairs with an NPTF port on the female end, which is pretty much the standard hookup for on-highway hydraulic lines on dump and refuse trucks. Flow restriction shouldn't be a concern at typical operating demands for that kind of rig.
