Flow Liquid on Time and on Target with Compact Nozzles from The Lee Company

Nozzles from The Lee Company are the most compact, economical, and reliable nozzles available anywhere. They’re designed for small size and light weight, providing critical lubrication and fuel delivery for motorsport vehicles. Lee nozzles serve one of two functions: provide an atomized hollow cone of spray or provide an accurate, solid stream of fluid for lubrication.

Atomizing nozzles may be used to help with fuel combustion in the engine. Alternatively, lube nozzles produce an accurate, solid stream of flow on target for cooling and lubrication applications. Off-the-shelf products range from orifices drilled to a certain diameter to target-tested nozzles with integral etched safety screens. Many factors can affect the amount of lubrication that hits a target, such as temperature, pressure, and fluid. Optimizing the lubrication location can increase the time between maintenance or reduce the weight of a system by eliminating the need for excess lube oil. Therefore, The Lee Company 100% tests each lube nozzle for flow rate and capture efficiency.

The Lee Company has developed an extensive range of custom nozzle configurations to enhance our standard product line capabilities. Nozzles with unique envelopes are designed to meet customized dimensional and performance specifications. Lee HI-BAR® Safety Screens may be integrated directly on the inlet of the nozzle body to create added protection in a highly robust, one-piece design.

Other custom designs are optimized to perform under challenging conditions typical of an engine and include custom acceptance testing, such as:

  • A wide range of test fluids
  • Custom flow rates and tolerances
  • Multiple targets in a one-piece design
  • Elevated test temperatures

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.

Lee JELA® Lubrication Jets

Lee JELA Lubrication Jets generate a straight, well-defined fluid stream to a predetermined target with differential pressures of 10 to 200 psid. Lee JELA Lubrication Jets are 100% tested for capture efficiency, guaranteeing that over 90% of flow will hit a predetermined target two inches away. These units are ideal for directing streams of lubricating oil at critical bearings or cooling oil at meshing gears. Lubrication jets are available in four sizes from 0.125 to 0.343 of an inch with Lohm rates ranging from 200 to 7500 with a +/-15% tolerance. The 0.187 inch size is available with an integral safety screen and Lohm rate tolerance of +/-10%.

Lee Plug Jets

The Lee Plug Jet® offers an economical solution for fluid metering applications that do not require the accuracy, removability, or protective screens that are available in other, more sophisticated flow restrictors or nozzles. Lee Plug Jets are available in 416 stainless steel material in body diameters of 0.125, 0.187, and 0.250 of an inch, with chamfered orifices of 0.010 through 0.093 of an inch in diameter.
