Engineered for universal fitment across global hydraulic systems, these JIC male fittings support all mainstream hydraulic thread standards, including JIC 37° flare (SAE J514), NPTF dry seal, ORFS flat face (O-ring boss), BSPP/BSPT, and metric threads. Every unit is precision-machined to meet SAE J514, ISO 8434-2, and equivalent DIN 2353 specifications, ensuring a secure, consistent mating with female ports, adapters, valves, and quick-connect assemblies. This broad compatibility makes them a versatile choice for system retrofits, OEM production runs, and replacement part inventory for industrial and mobile equipment.
Purpose-built to withstand the rigors of heavy-duty construction and industrial environments, these male fittings deliver dependable leak-proof performance in high-pressure hydraulic systems. The design features precision-machined threads and optimized sealing surfaces: a 37° flare cone for robust metal-to-metal sealing, an O-ring groove for ORFS configurations, and tapered NPT threads compatible with industry-standard sealants. Manufactured from high-grade carbon steel with zinc plating for superior corrosion resistance, with optional 304/316 stainless steel available for harsh environments, these fittings resist continuous vibration, pressure spikes, and extreme thermal cycling. They maintain stable performance up to 3000–6000 PSI, with exact pressure ratings varying by size and thread type.
We offer a comprehensive range of JIC male fittings to accommodate every hydraulic routing requirement, with sizes spanning from 1/4" to 2" (DN 6–50 mm). Available configurations include straight, 45° elbow, 90° elbow, and swivel designs, each engineered to simplify installation and extend system service life. Swivel male ends enable full 360° rotation to eliminate hose twisting during assembly and operation, reducing wear on hydraulic hoses and improving ease of maintenance in dynamic applications. This flexible range makes our fittings suitable for everything from compact equipment hydraulic lines to large-scale industrial hydraulic circuits.
We support full end-to-end customization to match your unique hydraulic system and application requirements, with no compromise on industry-standard performance. Available customizations include material upgrades (such as stainless steel for corrosive or food-grade operating environments), specialized plating options (zinc, chrome, or phosphate), hybrid thread combinations (e.g., JIC male to NPT male), integrated crimp ferrules, and non-standard angles or configurations. We can also develop custom specifications to align with your exact pressure rating, hose type, fluid compatibility, or application needs, making us an ideal partner for OEMs and specialized project contractors.
Our JIC male threaded fittings are engineered to perform across a wide range of heavy-duty industrial and mobile applications, with a core focus on construction machinery and related sectors.
These fittings are the industry standard for hydraulic systems in excavators, wheel loaders, bulldozers, cranes, road rollers, and other heavy construction equipment, delivering reliable performance in high-vibration, high-pressure on-site environments.
Ideal for hydraulic circuits in tractors, harvesters, planters, sprayers, and other farm machinery, with corrosion-resistant options built to withstand exposure to dust, moisture, and harsh outdoor operating conditions.
Widely used in stationary industrial equipment including hydraulic presses, injection molding machines, metallurgical machinery, mining equipment, and manufacturing production lines, with consistent performance for continuous industrial operation.
Suitable for a broad range of mobile hydraulic applications, including aerial work platforms, sanitation vehicles, forklifts, and material handling equipment, with compact configurations and swivel designs to accommodate tight installation spaces.
