Standard-Compliant SAE J514 & ISO 8434-2 Stainless Steel Adapters
Fitsch is an industry-recognized China hydraulic adapter manufacturer and factory, engineering world-class Stainless Steel Hydraulic Adapters strictly compliant with SAE J514 and ISO 8434-2 international standards. These standards govern the dimensional and performance criteria for 37° flare (commonly known as JIC) fluid connectors, ensuring total design interchangeability with global machinery systems.
Manufactured from premium 304 and 316 stainless steel, our hydraulic adapters utilize a metal-to-metal sealing cone design. This configuration creates an impenetrable seal that performs exceptionally well in high-vibration, high-pressure, and highly corrosive fluid transmission lines. Whether for marine machinery, oil and gas distribution, or industrial manufacturing automation, our SAE J514 / ISO 8434-2 line provides high-security plumbing components.
Comprehensive Product Configurations & Specialized Types
We fabricate a diverse variety of standard stainless steel adapters across multiple geometries—including Straight, 90° Forged Elbows, 45° Elbows, and Tee layouts—specifically tailored into these high-demand configurations:
1. DKJ Swivel Elbow Adapters
Engineered for tight spaces and complex plumbing angles, our DKJ Swivel 90-Degree Elbows feature a robust female swivel nut design. This allows for effortless positioning and alignment of hydraulic lines during installation without twisting or stressing the rigid hose or tube.
2. JIC Male Plugs
Built strictly to SAE J514 dimensions, our JIC Male Plugs feature a precision-machined 37° external flare cone. They provide an airtight, high-pressure mechanical seal to securely block off unused manifold ports or terminate open JIC female fluid lines during system maintenance.
3. BSPT Hydraulic Adapters
Designed to seamlessly bridge different global thread standards, our BSPT (British Standard Pipe Tapered) adapters connect American JIC layouts into European and Asian machinery blocks. The tapered thread configuration self-seals via thread deformation, ensuring a reliable joint under high operating pressures.
4. Female JIC Plugs (Swivel Caps)
Our Female JIC Plugs are equipped with an internal 37° mating seat and a heavy-duty swivel nut. They act as secure caps to block off pressurized male JIC adapters and tube ends, keeping hydraulic systems free from external contaminants and fluid loss.
