Product Questions & Answers (4)

Question by: Cody J on Mar 29, 2025, 4:38 PM

Will this fitting hold up in a hydraulic system running at high pressure?

Answer by: Customer Support on Mar 31, 2025, 6:19 AM

This Danfoss/Eaton Aeroquip fitting is designed to work with 4-wire spiral hoses, which are typically used in high-pressure hydraulic applications. Just make sure your hose and system pressures are within the fitting's rated limits.

does this fitting work down to real cold temps, like negative 40 degrees or so?

Answer by: Customer Support on Apr 17, 2025, 1:27 PM

Rated for a minimum working temperature of -40 degrees, so genuine cold weather operation is covered. The carbon steel construction and Dura-Kote plating hold up in harsh environments without adding a lot of maintenance headache to your routine.

Question by: Lee G on Aug 26, 2025, 9:02 AM

got a -12 4-wire spiral hose, is this the right fitting for it?

Answer by: Customer Support on Aug 28, 2025, 8:30 AM

For hose fit, the key callout here is the hose dash size. This fitting is built for a -12 hose and it is a 4-wire spiral TTC fitting assembly, so it matches that hose size and style.

Question by: Kent R on Feb 25, 2026, 2:47 PM

what's the lowest temp this fitting can handle before it starts giving you trouble?

Answer by: Customer Support on Feb 27, 2026, 10:09 AM

Carbon steel construction and the Dura-Kote plating on this fitting are rated down to negative 40 degrees, so cold weather operation and freezing environments are well within range. That floor covers most industrial and outdoor applications without any issue.
