Product Questions & Answers (2)

Question by: Curt S on Jan 17, 2026, 9:17 AM
What kind of corrosion resistance can I expect from this fitting?
Answer by: Customer Support on Jan 19, 2026, 6:01 AM
The Dura-Kote plating is included to give it superior corrosion resistance, helping the hose assembly last longer.
Question by: Randy S on Apr 16, 2025, 1:10 PM
Got a -8 hose I need to terminate with a female swivel on the end, angled at 45 degrees. This the right fitting for that?
Answer by: Customer Support on Apr 18, 2025, 6:40 AM
For a -8 hose dash size with a female swivel DIN 24 seat and a 45-degree elbow, yes, that is exactly what this fitting is built for. It is a permanent-style assembly, so keep in mind it is meant to be crimped or permanently attached rather than field-reusable. The carbon steel construction with Dura-Kote plating holds up well in environments where corrosion is a concern, which helps extend the life of the whole hose assembly.
