Product Questions & Answers (5)
Question by: Harvey W on Mar 4, 2026, 6:42 AM
Will this fitting hold up in a hydraulic system running around 3000 PSI?
Answer by: Customer Support on Mar 6, 2026, 6:50 AM
Dura-Kote plating on this fitting provides superior corrosion resistance, and the system engineering extends hose assembly life, so it should perform well under pressure within expected hydraulic applications.

got a -12 hose, is this the right dash size fitting or am i mixin stuff up
Answer by: Customer Support on Jul 1, 2025, 6:43 AM
For sizing, the key callout here is the hose dash size. This fitting is listed as a -12, so it matches a -12 hose size.
Question by: Patty H on Dec 28, 2025, 8:52 PM
does this fitting work with -12 hose on 4-wire spiral assemblies or is it only for certain builds
Answer by: Customer Support on Dec 30, 2025, 7:21 AM
Carbon steel construction and a -12 hose dash size make it a solid match for 4-wire spiral hose assemblies at that size. The Dura-Kote plating adds a layer of corrosion resistance that holds up well in demanding environments, so it's not just built for light-duty work.
Question by: Harvey W on Dec 14, 2025, 8:19 PM
Does the corrosion resistance on this fitting hold up when its exposed to moisture or harsh washdown conditions regular like?
Answer by: Customer Support on Dec 16, 2025, 2:48 PM
Dura-Kote plating is what sets this one apart from standard carbon steel fittings. That coating is specifically applied to fight off corrosion over time, which makes it a solid pick for environments where moisture, humidity, or general exposure to the elements is part of the daily reality. Carbon steel on its own would be more vulnerable, but the Dura-Kote finish gives it meaningful added protection and extends the working life of the whole hose assembly.
Question by: Bobby P on May 5, 2025, 4:16 PM
trying to match up a hose end here, is 4S20DS12 the one with the metric female end and a -12 hose dash size?
Answer by: Customer Support on May 6, 2025, 5:07 PM
For fit confirmation, 4S20DS12 is a fitting assembly with a metric female end (End Type 1: Metric, End Gender 1: female) and it is built for hose dash size -12.
