Pump leather cup

Leather used for industrial purposes is obtained from the tanning of animal skins and exists mainly in two types: - vegetable tannin (natural), from which a rigid, resistant and fairly permeable leather is obtained.
The tanned leather gaskets are used for hydraulic seals (operating pressure up to 250 atm and temperature 40 - 60°C).

- chrome mineral, from which a soft and oil-resistant leather is obtained. The chrome-tanned leather gaskets are used for hydraulic seals (operating pressure up to 350 atm and temperature 80 - 100°C).
In both cases the breaking strength is at least 3 kg/mm2.

Upon request, possibility of providing perforated and/or customized caps
