Agricultural harvesters and sprayers
In articulated boom circuits and hydraulic controls exposed to constant vibration and uneven terrain, DKO hydraulic adapters maintain stable sealing, help mitigate soil contamination from oil, and reduce corrective interventions. The dual-sealing system withstands rapid cycles and pressure spikes typical of field maneuvers, preserving system efficiency.
Tractors and soil preparation implements
In the cylinders of reversible plows, leveling harrows, and subsoilers, the 24° profile with O-ring delivers a robust connection against impacts and cyclic loads, ensuring precise actuation response. Torque repeatability reduces loosening and sustains productivity throughout extended working hours.
Dump bodies and road trucks
During the tipping of dump bodies and platforms, DKO fittings contribute to safe and continuous operation, maintaining complete sealing throughout repetitive cycles. Their high torque resistance helps preserve assembly integrity after maintenance and periodic inspections in road fleets.
Mowers and side sweepers
Exposed to dust, debris, and temperature fluctuations, articulated arm systems benefit from the resilient sealing of the O-ring and conical seat, reducing microleaks and maintaining stable pressure. This extends maintenance intervals and optimizes equipment availability.
Presses and compactors
In machines operating under constantly high pressure, the dual-sealing system prevents progressive fluid loss that can compromise force and speed. The result is a more consistent cycle, lower oil consumption, and better hourly output, especially in continuous industrial operations.

In general, yes, thanks to the metric and UNF options and the use of adapters when necessary. Check the thread/port pair and the machine pattern.
Fewer microleaks, faster assembly and less rework, which translates into more available machines and lower fluid consumption throughout the life cycle.
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.
Use PTFE tape if the connection will be retightened periodically. Prefer anaerobic sealant for permanent sealing and greater vibration resistance.
In agricultural hydraulic circuits, seal failures can halt a harvester during peak harvest season and drive up maintenance costs. The dual sealing system with O-ring effectively eliminates leaks even under intense vibration and pressure spikes, cutting unplanned downtime and fluid losses by up to 95% when installed per specifications.
The 24° self-centering cone speeds up assembly by up to 40% compared to conventional connections, minimizes rework, and enhances torque repeatability.
Helesul DKO hydraulic adapters (Double Cone O-ring) are engineered for high-reliability sealing in high-pressure hydraulic systems, combining a 24° self-centering cone and O-ring for consistent performance in agricultural machinery and road applications.
With robust construction, they reduce leaks, simplify installation, and boost equipment uptime even under vibration, intense cycles, and harsh environments.
All Helesul hydraulic adapters are manufactured to ISO, SAE, and DIN standards, ensuring interchangeability, safety, and predictable field performance.
