HWGZ is made by PPDI. It is of high elasticity with excellent performance. Great resistance to media and dirt; Longer service life of 6 years (10000 hours).
The ripple grooves prevent external rainwater from the gap at the junction of metal surfaces during movement, and also stop other pollutants from entering the interior of the cylinder.
The elevated dust lip provides better holding force and effectively scrapes dirt off the piston rod.
The inner lip is equipped with a conical oil drain hole, similar to a check valve, which easily releases oil pressure inside the dust seal and prevents pollutants from entering the cylinder.
The R-angle lip design can effectively protect the oil film on the piston rod and prevent oil leaks from the oil ring on the piston rod.
