This flow restrictor is a novel solution to removing trapped air in hydraulic systems while keeping hydraulic losses to a minimum. Utilizing a small precision flow orifice, the 5.5 mm Insert Air Bleed Orifice Restrictor allows trapped air to escape but is small enough to restrict most hydraulic flow, minimizing system losses. It features an integrated safety screen for contamination protection and uses The Lee Company’s field-proven insert principle that provides secure retention without the need for threads, O-rings, or sealants.
