Piston 708-3S-13520 LPD25 Description
The YNF15415 piston (708-3S-13520) is a swash plate piston used in LPD25 hydraulic pumps for excavators. It is a key part that transforms rotary motion into hydraulic pressure, ensuring efficient oil flow and pump stability.
This piston is manufactured from premium alloy steel and undergoes CNC precision machining, surface hardening, and heat treatment to deliver excellent wear resistance, fatigue resistance, and dimensional accuracy. It is engineered to perform reliably under high hydraulic pressure and continuous heavy-duty excavation conditions.
Replacing worn pistons helps avoid reduced hydraulic efficiency, oil leakage, and premature pump damage, thus reducing downtime. YNF aftermarket pistons are built to OEM specifications, offering a cost-effective and reliable choice for excavator repair shops, fleet operators, and global distributors.
