Lee Visco Jet® Multi-Orifice Restrictors
The Lee Visco Jet® is one of our most unique innovations. It creates a highly complex fluid passage with a series of individual spin chambers and orifices. This provides an increase in flow passage as great as 25 times that of a corresponding (same Lohm rate) single-stage restrictor, with a corresponding reduction in velocity.
Visco technology offers multiple benefits, including increased resistance to contamination and reduced erosion. Its design prevents cavitation and creates a degree of viscosity compensation. To learn more about how Lee Visco Jet technology works, watch this short video.
Visco Jets are available in flow rates up to 313,000 Lohms in a 0.187 inch diameter cartridge and up to 2.2 million Lohms in a 0.43-inch diameter cartridge. There is no other product available that can provide this level of restriction with such a large minimum passage in such a tiny package.

Lee A.F.O.® (Axial Force Only) Plugs
Unlike other plugs in our product family, A.F.O. Plugs are both removable and reusable due to their threaded design, which allows technicians easy access to sealed passageways. In spite of this, the A.F.O. Plug still seals up to 56,000 psi. Each plug features a floating seal that self-aligns, allowing for threaded holes that aren’t concentric with the through-hole. Lastly, the A.F.O. designation means that no radial force is applied during installation, making this component suitable for thinner-walled housings. See Installation Process Specification P1013 (which applies to all A.F.O. Plugs) for more information.
A.F.O. Plugs are made from stainless steel and are available in standard diameters from 0.190 to 0.625 of an inch.

HI-BAR® Inlet Safety Screen, Flareless AS33514E04 to Port AS930-04
Lee HI-BAR Inlet Safety Screens save space and weight by incorporating the inlet screen directly into the boss fitting end rather than the more traditional approach of having the inlet screen installed in the manifold directly below the fitting. This unique design also offers greater flow and dirt holding capacity than a design that completely encapsulates the screen in the fitting. Lee HI-BAR Inlet Safety Screens are machined entirely from 15-5PH stainless steel and are rugged enough to withstand pressure differentials up to 6000 psi without burst or collapse. Each component is 100% proof pressure tested before shipment to ensure reliable performance. These screens are available in -4, -6, -8, and -10 configurations (AS33514 flareless tube to AS930 port fitting ends), which can be installed into a standard boss per AS33649 or equivalent. Eight standard hole sizes ranging from 50 to 500 micron are available.
Spray Nozzles
Lee Spin Jet® spray nozzles utilize unique vortices and flow passages to provide a finely atomized 70° hollow cone spray pattern. The Lee Company has state-of-the-art equipment to analyze spray patterns and droplet size to determine performance across different fluids, pressures, and temperatures. Standard options are available from 6000 to 18,000 Lohms, each with a safety screen to protect against rogue particles. The nozzles are rated for operation at service temperatures up to 700°F (371°C) max and for continuous service up to 400°F (204°C) max.
