Lee Bender Jet Multi-Orifice Restrictors
As the name suggests, Lee Bender Jets use multiple offset orifices in series. Each additional restriction causes an increased reduction in flow. This produces an effect that results in an increased minimum passage size for a given Lohm rate. The valve’s components are protected with two integral safety screens for bi-directional flow and are available calibrated to a ±5% tolerance in the range of 125 to 9500 Lohms.

Selective Shuttle Valves
This is our standard non-biased loose-ball design. Available in 0.187, 0.281, 0.375, and 0.500 inch diameters, these are the most economical configuration. The maximum shuttling pressure is just 1 psid. The valves are rated for leakage of fewer than 1 mL per minute.
Lee Components in Unions
Virtually every 0.187, 0.250, and 0.281 inch diameter Lee insert is offered already installed in appropriately sized flared, flareless, or dynamic beam seal unions. These unions are made of 304 stainless steel (code “J” in military standards) or 6AL-4V Titanium (code “T”). All Lee Unions have a unique hex wrench arrangement to distinguish them from simple unions and permanent external marking to identify the insert.
The configuration of these unions has been carefully chosen to accommodate most of the 0.187, 0.250, and 0.281 inch Lee inserts, and yet maintain both minimum envelope and weight. These units incorporate the high-root radius UNJF threads to minimize stress concentrations with Class 3A tolerances. All fitting-end dimensions are, except for the internal diameters, in general accordance with the appropriate AS4375E4 and E6, AS4395E04 and E06, and AS85720/1-04 and −06 specifications.
Every Lee Union with an insert installed is proof pressure tested; flared and flareless to 6000 psid and dynamic beam seal to 16,000 psid. Maximum working differential pressure is a function of the particular Lee insert specified (refer to the appropriate insert section).

Lee Components in Ring Locked Adapters
Virtually all Lee miniature components, including check valves, flow controls, restrictors, and screens, are available already installed or built into Ring Locked Adapters. Design engineers can now take advantage of the unused space in their Ring Locked Adapters to save space and weight in their manifolds.
The Lee Company offers all these products in Ring Locked Adapters with three different tube ends: dynamic beam seal, flareless, and metric dynamic beam seal (8° 30’ lip-seal). Dynamic beam seal and flareless tube versions range in size from −4 to −10 (1/4 to 5/8 inch) and metric lip-seal versions range from 6 to 16 mm nominal tube O.D. Titanium has been selected as the adapter material for the lowest possible weight. All Ring Locked Adapters containing Lee components have blue lock rings to distinguish them from ordinary adapters, and permanent external marking to identify the function of the product inside.
