Question by: Earl P on Jun 19, 2025, 7:51 AM

fitting's got a -12 hose dash size on it, does that line up with standard 4-wire spiral hose assemblies for heavy equipment?

Answer by: Customer Support on Jun 21, 2025, 6:03 AM

For 4-wire spiral hose assemblies sized at -12, this fitting is built to match up correctly. The TTC (Tough Tough Coupling) design from Eaton Aeroquip is a system-engineered solution, meaning the fitting and hose are intended to work together as a matched assembly to extend overall service life. The ORS end on the female side gives you a clean, leak-resistant connection point on the equipment end, while the other end handles line, hose, or tube connections. Carbon steel construction keeps it tough enough for the kind of high-pressure spiral hose work these assemblies are typically put through.
