LEATHER

Mechanical packings made of leather, chrome tanned or tannin, being made of entirely natural material, have a series of advantages over those made of other materials. Individual fibers, each made up of groups of small fibers or filaments casually intertwined, make leather inherently foldable, strong, and highly resistant to abrasion and wear.

Advantages:
They have a low coefficient of friction:
They generate little heat when used, and as a consequence high efficiency and long life are obtained. Due to their fibrous structure, they create a film in the pressure medium that in most cases acts as a lubricant and further reduces the coefficient of friction. It does not require relatively high pressure to overcome inertia. They work smoothly and do not cause noise at low pressure and slow speeds.

They do not flow easily:
Due to the arrangement of its freely intertwined fibers, leather has an inherent tensile strength and great hardness. Gaskets can withstand very high pressures with minimal loss.

They do not scratch and are anti-abrasive, and at the same time they tend to be polished on the metal parts where they work.

They allow greater metal tolerances:
Due to its high resistance to traction and cold fluid, greater metal tolerances can be used than with other materials. They reduce losses to a minimum and their use allows pressures to be maintained for relatively long periods.

Acts at low temperatures:
The skin is not affected by temperatures below 0 degrees, and its use is purely routine at 50ºC below zero.

Suitable for a wide range of pressures:
Molded in various formats, they can be used for both delicate low-pressure regulators and heavy hydraulic applications.

Low initial cost:
for its long life and relative simplicity of mold.

They can be stored indefinitely:
They are not affected by oxidation or sunlight.

Adaptable to different types of services Guys:
collars, glasses, hats, angles…

Applications:
for pump seals and hydraulic presses.
