Product List

Crimp hydraulic fittings are designed to be permanently attached to hydraulic hoses using a crimping machine. They are widely used in hose assemblies for construction equipment, agricultural machinery, mining equipment, trucks, industrial hydraulic systems, and repair service work. Since many hydraulic fittings look similar but use different thread forms and sealing methods, correct identification is important before quotation and production. Our team can help check thread type, sealing surface, hose size, fitting angle, and current part numbers to reduce mismatch, leakage, and rework risk.

Crimping Compatibility & Safety Reminder

Correct crimping is critical for hydraulic hose assembly performance. Before production or assembly, the hose type, fitting structure, ferrule design, crimping machine, die set, and final crimp diameter should be confirmed carefully to reduce leakage, hose pull-off, premature failure, and customer complaints.

Hose & Fitting Match

The hose type and fitting structure must be matched before crimping. A fitting used for braided hose may not be suitable for spiral hose, thermoplastic hose, or PTFE hose.

Correct Crimp Diameter

The final crimp diameter directly affects hose assembly safety. If the crimp is too loose, the hose may pull off. If it is too tight, the hose tube or reinforcement may be damaged.

Ferrule Structure Check

For crimp fittings, the ferrule or sleeve structure should match the hose reinforcement and fitting stem. Wrong ferrule selection may cause poor gripping, leakage, or assembly failure.

Machine & Die Compatibility

Different crimping machines and die sets may produce different crimping results. Before bulk assembly, the machine, die set, and crimping data should be checked.

Pressure & Application Safety

The fitting should be selected according to working pressure, equipment type, temperature, and environment. Heavy-duty applications need stronger fitting and hose combinations.

Test Before Bulk Use

For new hose and fitting combinations, trial crimping and inspection are recommended before bulk use. This helps reduce leakage, hose pull-off, and customer complaints after delivery.

Crimp Hydraulic Fitting Manufacturing Process

Each hydraulic fitting is produced through a controlled manufacturing process to ensure reliable performance, precise dimensions, and consistent quality.

Topa hydraulic cylinder factory raw material cutting

Raw Material Preparation

The manufacturing process begins with selecting high-quality carbon steel bars. Each batch of raw material is inspected before entering production to guarantee stable quality for one-piece hydraulic fittings used in high-pressure systems.

2. hot Forging Topa

Hot Forging

During hot forging, the heated steel is pressed into the initial shape of the hydraulic fitting body. This process improves the internal metal structure and enhances strength compared with simple machining.

CNC robotic machine Topa

CNC Precision Machining

After forging, the fittings move to CNC machining centers where the outer shape, hose tail, and connection surfaces are precisely processed.

JIC Fitting Thread grill

Thread Processing

Thread cutting is one of the most critical stages in hydraulic fitting production. Precision machines create threads such as JIC, BSP, NPTF, or ORFS according to international standards.

Hydraulic Fittings Galvanized machine

Surface Treatment

To improve corrosion resistance and service life, the fittings undergo protective surface treatment. Zinc plating or other coatings create a protective layer that helps one-piece hydraulic fittings perform reliably in harsh environments.

dimension Test Topa

Quality Inspection

Before shipment, each batch of fittings goes through multiple quality inspections. These checks include dimensional measurement, thread gauge testing, and visual surface inspection.

Hardness Testing

Material hardness is tested to ensure the fitting has the required strength and durability. Proper hardness helps prevent deformation, cracking, or failure under high-pressure working conditions.

dimension Test Topa

Dimensional Inspection

Key dimensions such as thread size, hose tail diameter, and overall length are measured using precision tools. Accurate dimensions ensure proper assembly and compatibility with hydraulic hoses and adapters.

Spectrometer Topa

Surface Roughness Testing

Surface roughness is inspected to ensure proper sealing performance. A controlled surface finish helps reduce leakage risks and improves connection reliability.

profile projector test Topa

Profile Inspection

Profile testing is used to verify the shape and angle of threads and sealing surfaces. This ensures that each fitting matches standard specifications such as JIC, BSP, or ORFS connections.

Hydraulic Fitting Salt Spray Test

Salt Spray Testing

Salt spray testing evaluates corrosion resistance of the plated surface. This helps ensure the fittings can perform reliably in humid, outdoor, or harsh operating environments.

burst Test

Burst Pressure Testing

Burst testing is conducted on selected samples to verify pressure resistance. This ensures the fittings can withstand high-pressure conditions without failure.
