Comprehensive choice,
high quality standard


UFI hydraulic accessories programme has been carefully designed to offer a range of components suited to the demands of building hydraulic systems in most industrial and mobile applications.

Whether you require simple filler breathers or precise electrical level switches, the accessories range should provide you with the choice you need.

User benefits:

  • Tank breather filters for the filtration of the incoming air to the tanks of hydraulic systems.
  • Tank filler and breather filter for the filtration of the incoming air to the tanks of hydraulic systems and for filling the oil on the hydraulic tank.
  • Filler caps for filling oil in the hydraulic tanks
  • Visual and electrical level indicators of fluid for hydraulic tank.
  • Oil bath air filters for prolonged use in particularly dusty environments, to ensure an excellent level of filtering and a long working life. For very dusty environments can be provided with cyclone prefiltering


Filling breathers

Filling plugs with inbuilt air breather; flanged tank connection with standard dimensions; protection basket against ingression of coarse parts (removable for CFA23); zinc plated steel body and chrome plated steel cap; seals by cork (NBR - Nitrile for pressurized version only).

Filter element

Filter element (not replaceable):
Impregnated cellulose 3µm (filtration degree in air)
Polyurathan foam 10µm (filtration degree in air)
For sizes CFA21 & CFA22 only the plug has a safety chain.
