Positive Seal <br />Sump Entry <br />Flexible entry boots have been <br />tested to withstand a minimum of <br />6' of liquid head pressure. These <br />seals provide a studded flange <br />connection to create a positive <br />and secure seal where the rubber <br />contacts the sump wall and also <br />around the pipe or conduit. <br />Tightening down on a series of <br />stud fasteners with a compression ring provides a high <br />compression mechanical seal compared to screw on <br />type bulkhead seals. <br />Angled Entries <br />Pipe and conduit entering the <br />containment sumps may not be <br />perpendicular with the sump wall. <br />Angled entries are generally a <br />result of directional plumbing <br />restrictions on the inside of the <br />containment chamber due to <br />space limitations. Flexible entry <br />boots are flexible enough to <br />permit angled pipe or conduit entries (on two axises) <br />into the sidewall of a containment chamber. All flexible <br />entry boots permit angled entries up to a 15 degree <br />angle off the perpendicular center line in any direction <br />without leaking or putting undue stress on the pipe or <br />conduit seal. <br />Universal Alignment <br />These seals are also capable <br />of universal pipe alignment either <br />up and down or side to side. This <br />feature allows accommodation <br />of pipe entry holes which are <br />installed slightly off exact center <br />alignment in the chamber wall. <br />This movement will prevent the <br />chamber wall from putting undue <br />stress on the pipe coupling/fitting joint and the entry <br />boot as well. For flexible piping applications within <br />dispenser sumps, the stresses on the pipe fittings below <br />the product inlets are minimized by the boot's flexibility. <br />Quality Materials <br />Corrosion Resistance <br />The exterior studded metal <br />compression ring that <br />provides the positive sealing <br />pressure is encapsulated <br />within rubber to protect it from <br />corrosion. More than a 1/8" <br />of rubber isolates the metallic <br />studded ring from the ground <br />environment. All studs are <br />made of 401 stainless steel and are only exposed <br />on the inside of the containment sump. <br />Chemical Compatibility <br />All seals are made of <br />specially formulated <br />Buna-N rubber <br />compound which has <br />been independently <br />tested to insure its <br />compatibility with a wide <br />assortment of chemicals. <br />These tests include measuring <br />the material's retention of properties as well as the <br />physical characteristics of the seal after exposure. <br />Easy to Install <br />Environ Products, Inc.
