Titan 0278339 Hydraulic Piston for SprayTech AirCoat & ED655 Plus

The Titan 0278339 Hydraulic Piston is a genuine Titan-manufactured replacement component designed for use on compatible SprayTech AirCoat and ED655 Plus equipment. This precision-machined piston is a critical element of the hydraulic system, converting fluid pressure into linear mechanical force to drive the pump or other hydraulic actuators.

In AirCoat systems, precise hydraulic control is essential for achieving the fine atomization and consistent finish that these systems are known for. Over time, pistons can wear due to contamination, seal degradation, or normal use, leading to pressure loss, erratic operation, and reduced coating quality. Replacing a worn hydraulic piston with this genuine Titan component restores proper system pressure, ensures smooth and consistent operation, and maintains the high-quality finish expected from SprayTech equipment.

Service Guidance: If you notice inconsistent spray patterns, pressure fluctuations, hydraulic fluid leaks, or reduced system performance, inspect the hydraulic piston and associated seals. Replace if worn, scored, or damaged.

Frequently Asked Questions

It is a hydraulic piston manufactured by Titan, designed as a direct replacement component for converting hydraulic pressure into mechanical force on compatible SprayTech AirCoat and ED655 Plus equipment.

Common signs include pressure fluctuations, inconsistent spray patterns, hydraulic fluid leaks, erratic system operation, or visible wear/scoring on the piston surface during inspection.

It fits SprayTech AirCoat (Model Number 0508074A) and SprayTech ED655 Plus models.

Installation requires careful disassembly of the hydraulic cylinder. Remove the old piston, clean the cylinder bore thoroughly, lubricate new seals and piston with clean hydraulic fluid, and carefully insert the piston to avoid seal damage. Ensure proper orientation and torque fasteners to specifications. Bleed the hydraulic system according to the service manual before operation. Always refer to your SprayTech service manual for detailed procedures and safety precautions.
