Question by: Wayne H on Mar 23, 2026, 12:22 PM
trying to swap out a fitting on a -4 hose, is this 1AA4FS4 the right size for that?
Answer by: Customer Support on Mar 25, 2026, 6:34 AM
For sizing, the key match is the hose dash size. This fitting is listed as a -4, so it lines up with a -4 hose assembly.
Question by: Earl G on Aug 2, 2025, 6:52 PM
trying to swap out a fitting on a -4 hose, is this the kind with the female SAE 45 degree swivel on it?
Answer by: Customer Support on Aug 4, 2025, 2:30 PM
The key callouts are right in the part details. It is a 1A Series crimp hose fitting with a female SAE 45 swivel end, and it is sized for a -4 hose dash.
