Lee Cross Port Plugs

Lee Cross Port Plugs are a plugging solution specifically engineered to seal cross port passageways. This configuration is a variant of the original Lee Plug® that set industry standards over 65 years ago. A smooth wall design combined with the field-proven controlled expansion principle creates a permanent, leakproof seal, without the need for o-rings or sealants. Installation is simple, reliable, and requires no maintenance.

Lee Cross Port Plugs are constructed from 6Al -4V Titanium. They have been qualified for proof pressures over 20,000 psi and at temperatures up to 400°F. Configurations are available in .250, .281, and .343 inch diameters.

Lee Cross Port Plugs are ideal for isolating sections of a fluidic manifold. They are also used to plug deep passageways that are difficult to access with conventional sealing methods. Typical applications are found in down-hole oil drilling, wireline and completion tools, as well as in aircraft, high performance race cars, or anywhere else a leak-proof seal may be required.
