The hydraulic tank cover 151.57.156 (old model) is installed on the neck of the hydraulic system tank 151.57.031-2. The tightness of the connection between the cover and the tank is ensured by gasket 151.57.157, which prevents leakage of working fluid and protects the hydraulic system from contamination.
The cover is used in the hydraulic system of the HTZ T-150, T-150K, T-151, T-151K, T-156 tractors, as well as on other HTZ models equipped with an old-style hydraulic system.
