Breather caps

Breather caps

Designed to protect equipment against moisture and particle contamination, our range of breather caps are essential components for many industrial sectors. They are very efficient at preventing dirt particles from entering the equipment.

In hydraulic systems, air expands significantly above 72°C. This causes vibration and unsteady function of machinery. Hydraulic caps resolve this issue by releasing the trapped air and rebalancing the system. They are a solution designed to keep the internal tank pressure within certain values. These components prevent malfunction caused by alterations in pressure levels. When used on transporting equipment such as petrol tankers, breather plugs help prevent explosions of combustible materials.

Hydraulic breather plugs can come with specifications such as splash guard, with dipstick, with simple or double valve and even with vacuum breaker valve. They come in threaded, bayonet, and screw-on configurations, and in various designs and patterns. You can find a whole host of them in the Elesa catalogue.

Elesa breather plugs are made from the following quality materials:

  • Technopolymer
  • Aluminium
  • Stainless steel
  • Steel

Elesa breather caps hold the ELESA original design award from the IF Hannover.

Our SFP hydraulic components are complete with an original design splash guard that prevents oil loss. This range is particularly suitable for use in strong conditions where oil has the potential to be splashed against the breather cap.

This model is also available in the ATEX series in accordance with the Essential Health and Safety Requirements which makes it the ideal component for use in environments subject to risk of explosion.

Also within our range is are straining baskets and side flanged baskets for threaded or bayonet caps. Made from tough, durable technopolymer, we also supply baskets that can be mounted vertically.

Alongside our hydraulic breather cap components are breathable membrane filters made from stainless steel and aluminium. They are ideal for use on machinery and equipment to guarantee the pressure balance between the internal and external environment. They prevent traces of dirt, oil, or water vapour from entering inside and also prevent oil dripping into the surrounding area. They should be installed in a vertical position for optimum operation.
