As a professional JIC interlock fittings manufacturer, Huatai specializes in producing high-strength hydraulic hose fittings designed for demanding industrial fluid transfer systems. Our JIC interlock hydraulic fittings are engineered for high-pressure applications where safety, leak prevention, and long service life are critical.
We supply a full range of hydraulic interlock fittings for OEM manufacturers, hydraulic hose assemblers, industrial distributors, construction equipment manufacturers, mining machinery companies, and heavy-duty transportation industries worldwide.
With advanced CNC machining, strict quality control, and flexible OEM customization capabilities, Huatai delivers reliable JIC hose fittings that meet international hydraulic connection standards.
JIC interlock fittings are heavy-duty hydraulic hose fittings designed for high-pressure hydraulic systems. They use a 37-degree flare sealing surface according to SAE and ISO standards, providing excellent sealing performance and vibration resistance.
Compared with standard crimp fittings, interlock hose fittings are specially designed for spiral hydraulic hoses and ultra-high-pressure applications. The interlock structure securely locks the inner and outer layers of the hose, greatly improving hose retention and assembly safety.
JIC interlock hydraulic fittings are widely used in:
Construction machinery
Mining equipment
Agricultural machinery
Oil & gas hydraulic systems
Marine hydraulic applications
Industrial hydraulic power units
Heavy-duty trucks and transportation equipment
Our hydraulic interlock fittings are designed for multi-spiral hydraulic hoses and can withstand extremely high working pressures in demanding operating environments.
The precision-machined 37° flare connection ensures reliable sealing performance and minimizes hydraulic fluid leakage.
The interlock crimping structure enhances the connection between hose and fitting, reducing the risk of hose blow-off under pressure spikes.
Available surface treatments include:
Zinc plated hydraulic fittings
Cr6-free plating
Nickel plated hydraulic fittings
Stainless steel hydraulic fittings
These options improve corrosion resistance for outdoor and marine environments.
Compatible with:
SAE 100R12 hose
SAE 100R13 hose
SAE 100R15 hose
Spiral hydraulic hoses
High-pressure rubber hoses
