Excavator
Piston BKZT
This product is used in combination with piston seals and wear-resistant rings to prevent damage to the seals in the cylinder due to contamination from external substances, ensuring a long service life for the seals. When used in conjunction with piston rod seals and metal liners, the impregnation function of polytetrafluoroethylene resin helps prevent damage to the piston rod. It features a back pressure relief groove and an oil pressure bypass groove to prevent the accumulation of oil pressure.
