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.

When replacing the hydraulic piston, these associated components are often inspected or replaced to ensure a complete repair.
Always replace seals when replacing the piston to ensure proper sealing and prevent leaks.
Inspect cylinder bore for scoring or wear; replace if damaged to prevent piston damage.
Check fluid condition and replace filter if contamination caused piston wear.
