Cylindrical plug QIP

The Lee QIP was developed to provide an easier method of handling and installing the smallest plug sizes. This is accomplished by pre-installing the pin into the plug. This pre-assembled component adapts more easily to automated installation. Despite their smaller size, these plugs experience no loss of strength, with proof pressures up to 12,000 psi. The Lee QIP is available in aluminum and is offered in four standard sizes: 0.093, 0.125, 0.156, and 0.187 inch diameters. The .093 inch 2024 aluminum Quick Installation Plug is our smallest QIP. As a pre-assembled plug set, it combines ease of handling and installation with the proven reliability and performance of Lee Plug expansion plugs. When traditional manufacturing requires the use of cross-drilled holes, or when additive manufacturing housings need access points for sub-components, Lee Plugs continue to be the simplest, most successful method to seal drilled holes for critical applications. Upon installation of the pin, controlled expansion causes the lands and grooves of the plug to “bite” into the surrounding material forming independent seals and retaining rings. The result is a trouble-free, leak-proof seal for both liquids and gasses. Simplified installation. Uses Lee field-proven controlled expansion principal. High proof pressures, up to 10,000 psi (69 MPa).
