Premium Stainless Steel JIC Fittings: High-Pressure Leak-Free Connections
Fitsch is a leading China hydraulic fitting manufacturer and factory, specialized in engineering premium Stainless Steel JIC (Joint Industry Council) 37° Flare Fittings. Built strictly to SAE J514 and ISO 8434-2 international standards, our JIC adapters ensure maximum dependability, high-pressure tolerance, and exceptional corrosion resistance across severe industrial environments.
By utilizing high-grade 304 and 316 stainless steel, our JIC flare adapters eliminate the risk of systemic fluid oxidation and premature thread galling. The metal-to-metal sealing principle provides a simple yet highly reliable connection, making it the preferred choice for marine, oil and gas, chemical processing, and mobile heavy equipment.
Comprehensive 5 Core Product Types & Configurations
We manufacture and supply a comprehensive catalog of stainless JIC adapters across Straight, 90-Degree Elbow, 45-Degree Elbow, and Tee configurations to suit any hydraulic plumbing layout:
1. JIC Union & Bulkhead Fittings
JIC Union (Straight, Elbow, Tee): Designed to seamlessly join two or more JIC tube lines or hose assemblies together.
JIC Bulkhead Union: Features an extended body and structural locknut to safely route hydraulic fluid lines straight through panels, enclosures, or structural bulkheads without stress or vibration damage.
2. JIC to NPT Thread Adapters
Connects American standard tapered pipe threads to standard 37° flare systems. Available in male/female combinations across straight, 90° forged elbows, and branching tee designs.
3. JIC to BSPT Thread Adapters
Bridges British Standard Pipe Taper (BSPT) ports to standard JIC tube setups, common in European and Asian machinery setups.
4. JIC to SAE ORB (O-Ring Boss) Adapters
Ideal for heavy-duty hydraulic manifolds and cylinders. The JIC 37-degree flare side secures your line, while the male SAE ORB side utilizes an elastomeric O-ring seal to prevent leaks under intense pressure spikes.
5. JIC to BSPP Thread with ED Seal (BSPP ED)
Combines parallel British threads (BSPP) with highly reliable, heavy-duty Elastic Seals (ED-seals). This configuration guarantees tight sealing in control valves and pump ports without needing thread tape or paste.
