Question by: Phil W on Mar 5, 2026, 7:10 AM
trying to match up a reusable fitting i’ve got on a -4 hose, is this one the JIC straight with the female SAE 37 end?
Answer by: Customer Support on Mar 6, 2026, 2:29 PM
For a -4 hose, this one lines up with the Danfoss and Eaton 1R Series reusable hose fittings in a JIC straight configuration, and it uses a female SAE 37 end on one side.
Question by: Todd C on Jun 10, 2025, 12:54 PM
What kind of hose is this fitting supposed to work with, and is the -4 dash size the only option here?
Answer by: Customer Support on Jun 11, 2025, 2:43 PM
Carbon steel construction and a -4 hose dash size puts this fitting in line with standard small-bore hydraulic hose applications. The -4 dash size corresponds to a quarter-inch nominal hose ID, so it's built for that specific hose size. If you need a different dash size, that would be a separate part number in the 1R Series lineup.
