Abstract: A penetration fitting is provided for forming a sealed penetration through an aperture of a sump wall. The penetration fitting includes a flanged coupling comprising a generally rigid coupler and an integral first flange extending around a portion of the coupler. The first flange is adapted to abut and be sealed against a first side of the sump wall around the aperture. The ends of the coupler further define first and second fittings, the second fitting adapted to extend through the aperture. A ring flange is provided that is adapted to be adhered to an outer circumferential portion of the coupler and to abut and be adhered to a second side of the sump wall around the aperture. Once sealed to the sump wall, the associated piping connections can be made.

Abstract: A spill containment device for a fluid storage tank filling system including a threaded riser pipe extending from a storage tank and a drop tube including a flange at one end with a conduit extending from the flange, through the riser pipe and into the storage tank. The spill containment device includes a tubular base having an inwardly protruding shoulder adapted to receive the flange of the drop tube, lower threads below the shoulder adapted to mate with the threaded riser pipe; and upper threads above the shoulder. A receptacle is attached to the tubular base, the receptacle having an open upper end. A threaded compression ring is provided, the threaded compression ring adapted to mate with the upper threads of the tubular base and attach the drop tube to the tubular base.

Abstract: A sump for inhibiting leakage of liquid includes a double wall for at least part of the sump, and an interstitial space between the double wall. An indicator liquid is located in the space, and a sensor is in fluid communication with the space such that a change in the pressure or liquid level in the interstitial space causes the sensor to indicate leakage into or from the interstitial space. The double wall includes a base, a wall directed upwardly from the base of the sump, and the upwardly directed wall includes an angular portion being directed at an angle from the base greater than 90 degrees relative to the base. A remote location of that portion is connected with a substantially upright wall portion for the sump. An aperture for an electrical conduit is located in the angular portion.

Abstract: A flexible penetration fitting is provided for sealing the hole through which a pipeline penetrates a wall of an underground containment box. The penetration fitting includes a flexible boot with a sealing flange for providing a first seal against the inside wall of the box. The sealing flange is held against the wall by a backing ring placed against the outside wall of the box. The backing ring includes a plurality of studs extending through the wall and into the box. A compression ring with a plurality of holes is placed over the sealing flange with the studs of the backing ring extending though the holes. A plurality of nuts are threaded to the studs to hold the sealing flange firmly against the inside wall of the box. The flexible boot also includes a sleeve for providing a second seal against the outside surface of the pipeline. The sleeve is stepped with different sized openings so as to be able to receive different sizes of pipelines.
