Introduction SPECIAL PRODUCTS The Lee Company offers many miniature flow control components other than the standard products described in this handbook. In fact, approximately 50% of all Lee products are special or custom items designed to meet the requirements of a specific application. The majority of these special products are minor variations of standard products and may differ only slightly in: lohm rate, cracking pressure, leakage, flow testing, materials, etc. . . The remainder are uniquely different from the “standards” described in this handbook and include the following: •...

Introduction LeeTHE PRINCIPLE OF LEE PLUG PERFORMANCE The Lee Plug is a cylindrical plug with a tapered hole part way through its center and numerous small grooves on its outside diameter. It is slipped into a reamed counterbore in the product. A tapered pin is then driven into the plug until the ends of the pin and the plug are flush with each other. Controlled expansion causes the lands and grooves of the plug to “bite” into the surrounding material forming independent seals and retaining rings. Result: a positive, reliable, leak and trouble-proof seal for both liquids and gases. This...

Lee Plugs are manufactured to exacting tolerances. Every process is precisely controlled. Critical dimensions are 100% checked and others are statistically checked. All plugs and pins are 100% visually inspected. In addition, every lot of Lee Pins and Plugs is production acceptance tested. A representative sample of the mating pin or plug are performance tested to a Lee Company process specification for installation, leakage, pin retention, proof pressure and thermal stability. Two certificates of performance (one for the pin lot and one for the plug lot) accompany every shipment of Lee...

and chemical limits per Lee Company specification. We do not approve the use of material meeting only the 416 specification. PLUG PROOF PRESSURE To assist designers in the proper selection of Lee Plugs, a “proof pressure” is given for up to three hole tolerances (Classes I, II, III). The Lee Plug proof pressure is the highest hydrostatic pressure that may be applied in the course of routine Production Acceptance testing. The Lee Plug proof pressure values stated in this Handbook are defined for Lee Plugs when installed into boss materials identical to that of the Plug. When installing Lee...
