Combine Harvesters and Agricultural Sprayers
In articulated bar circuits and hydraulic controls exposed to constant vibration and uneven terrain, DKO hydraulic adapters maintain stable sealing, mitigate soil contamination from oil, and reduce corrective interventions. The dual sealing withstands rapid cycles and pressure spikes typical of field maneuvers, preserving system efficiency.
Tractors and Soil Preparation Implements
In cylinders of reversible plows, leveling graders, and subsoilers, the 24° profile with O-ring provides robust connections against impacts and cyclic loads, ensuring precise actuation responses. Torque repeatability minimizes loosening and sustains productivity during extended work shifts.
Dump Trucks and Highway Trucks
In dump body and platform tipping operations, DKO connections enable safe and continuous performance, maintaining total sealing throughout repetitive cycles. High torque resistance helps preserve assembly integrity after periodic maintenance and inspections in road fleets.
Side Mowers and Sweepers
Exposed to dust, debris, and thermal variations, articulated arm systems benefit from the resilient O-ring sealing and conical seat, reducing micro-leaks and maintaining stable pressure. This extends maintenance intervals and optimizes equipment availability.
Presses and Compactors
In machines with constant high pressure, the dual sealing prevents progressive fluid losses that degrade force and speed. The result is more consistent cycles, lower oil consumption, and improved hourly output, especially in continuous industrial operations.
Use PTFE tape if the connection will be retightened periodically. Prefer anaerobic sealant for permanent sealing and greater vibration resistance.
In agricultural hydraulic circuits, sealing failures can bring a harvester to a halt during peak harvest and drive up maintenance costs. The dual sealing system with O-ring helps eliminate leaks even under intense vibration and pressure spikes, reducing unplanned downtime and fluid loss by up to 95% when installed according to specifications. The self-centering 24° cone accelerates assembly by up to 40% compared to conventional connections, reduces rework, and improves torque repeatability.
Helesul DKO (Double Cone O-ring) hydraulic adapters are engineered for high-reliability sealing in high-pressure hydraulic systems, combining a self-centering 24° cone and an O-ring to deliver consistent performance in agricultural machinery and road applications. With a robust construction, they reduce leaks, simplify assembly, and increase equipment uptime even under vibration, intense duty cycles, and harsh environments.
All Helesul hydraulic adapters are manufactured in accordance with ISO, SAE, and DIN standards, ensuring interchangeability, safety, and predictable field performance.
