DKO (Double Cone O-ring) adapters use a double O-ring sealing system, while traditional JICs have only one sealing cone. The DKO system reduces leaks by up to 98% and offers a useful life 3 times longer, with tolerance to multiple assembly and disassembly without loss of efficiency.
A JIC hydraulic adapter is a standardized connection component that uses a 37° conical thread (according to ISO 6149). It connects hoses, cylinders and valves in hydraulic systems, ensuring metal-to-metal sealing without the use of rubber rings. Widely adopted in agricultural, road machinery and industrial equipment.
JIC uses a 37° conical thread and metal-to-metal seal, while standards such as SAE use cylindrical threads. JIC offers greater resistance to high pressures (up to 280 bar), lower risk of leaks under vibration and guaranteed international compatibility. Therefore, it is preferred in agricultural implements and equipment that operate in severe conditions.
No. There are three completely different thread standards (BSP 55°, JIC 37°, SAE 45°). Mixing standards results in unsafe connections, leaks and permanent damage to components. Always check the standard of your system before any replacement. Although conversion adapters exist, they can introduce restriction points into the flow.
Use PTFE tape if the connection will be retightened periodically. Prefer anaerobic sealant for permanent sealing and greater vibration resistance.
JIC (Joint Industry Council) hydraulic adapters are essential components in fluid power transmission systems, ensuring secure and stable connections between hoses, cylinders, and valves. Widely used in agricultural machinery and road equipment, these adapters offer international standardization, streamlining maintenance and parts replacement. Their reliability and operational efficiency have made them the preferred choice for implement manufacturers and operators worldwide.
All Helesul hydraulic adapters are manufactured in compliance with ISO, SAE, and DIN standards, ensuring interchangeability, safety, and predictable field performance.
