Spiral hose fittings are specifically designed for use with spiral-reinforced hydraulic hoses, which combine multiple layers of steel wire spirals for enhanced strength and flexibility. These one-piece hose fittings ensure secure connections that can handle high pressures and dynamic movements typical in heavy-duty hydraulic systems.
Spiral hydraulic hoses are engineered for extremely high pressure and pulse applications — and they require fittings that can withstand the same intensity.
At HT Hydraulics, we design and manufacture spiral hose one-piece hydraulic fittings that provide robust, reliable, and long-lasting sealing performance, even under shock, flexing, and vibration.
Spiral hose one-piece fittings are pre-crimped fittings that integrate both the ferrule and insert in one body. They're specially machined with deeper biting teeth and precise core alignment, designed to perfectly fit:
4-wire spiral hoses (4SP, 4SH, SAE 100R12)
6-wire spiral hoses (SAE 100R13, R15)
High-pressure hydraulic circuits requiring extreme burst resistance
These fittings offer superior impulse performance, and eliminate the risk of mismatched ferrule-hose combinations in field assembly.
HT Hydraulics (Hebei Zhongke Huatai Fluid Technology Co., Ltd.) brings decades of hydraulic expertise and robust manufacturing capacity to deliver industrial-grade spiral hose fittings, including:
30,000㎡ manufacturing facility
400+ CNC machines & automated forging equipment
10 million+ fittings per year
Certified ISO 9001, IATF 16949, CE
