O-Z/Gedney™ Thru Wall Floor Seals

O-Zgedney

O-Z/Gedney™ thru wall and floor seals provide a positive means of sealing pipe, conduit or tube where they pass through a concrete foundation of a structure below grade or below ground water level or at entry points through a concrete wall or floor which must be sealed. The usual methods of making installations, such as using straight sleeves or pitch pockets, are generally not satisfactory for their effectiveness depends upon the skill and care of the installer. If the installation is not effective, leakage will occur. Considerable time and effort may be required to remake the seal. The O-Z/Gedney™ thru wall and floor seals assure watertight installations.

Features

  • Provide a watertight blockage between poured concrete and the fitting body. The watertight blockage is accomplished by specially designed fins cast on the outside of the fitting body, which permit the concrete, when it cures, to shrink around these fins and prevent water from creeping along the outside of the body
  • Provide a pressure seal between the fitting body and the outside diameter of any round casing penetrating a wall, floor or ceiling. Pressure sealing is based on an engineering principle that solid rubber-like materials are incompressible. If properly selected material is confined and is compressed, the material will flow to fill all voids, providing a very effective, long lasting seal. The sealing grommet is a shock absorber between the fitting and the casing. It allows axial movement of the casing, removing stresses from the casing. The PVC coated steel rings provide cathodic protection as it insulates the sealing fitting from the casing
  • Type FSK and WSK thru wall sealing fittings are used where a single casing penetrates the fitting. The FSC and WSC thru wall sealing fittings are used where multiple casings penetrate through one fitting
  • The Type FSK and Type FSC fittings are used for most sealing applications. They consist of a body and sealing assembly located on the inside of the structure, and an oversize sleeve which extends from the fitting to the outside of the structure wall. After the foundation is poured, the concrete forms are removed and the round casing is inserted into the body, providing a pressure-tight seal between the round casing and the body of the fitting. The sealing assembly is always available on the inside of the structure for retightening, in the event that sufficient tightening was not utilized during the initial installation
  • The WSK and the WSC fittings are the same as the Type FSK and FSC fittings except that they have a body and sealing assembly on both sides of the oversize sleeve. This provides a pressure seal on both sides of the wall. The Type WSK and WSC fittings can be used on applications where a seal is required on each side of the wall. The body and sealing assembly on the outside of the wall can also be used as a throttle to limit the pressure on the sealing assembly on the inside of the structure. This practice is used where applications require future provisions for replacing the inside sealing assembly when there is a high pressure on the outside wall
  • Another purpose for the Type WSK?and WSC fitting is to keep the round casing in the center of the fitting and not have it deflect in the oversize sleeve in the event of earth movement in the back fill
  • Sealing grommets have an expected life in excess of 20 years
  • The steel pressure ring is closely sized to fitting the inside diameter and outside diameter of the casing. It has a PVC coating that provides an insulation between the sealing assembly, and the casing to provide cathodic protection by eliminating stray electrical currents from flowing between the fitting and the casting (exception: multi-hole Type FSC/WSC sealing assemblies furnished with low water-absorbing high-impact thick phenolic plates in electrical applications)
  • Oversize sleeves have a marker strip to facilitate field-cutting of sleeves to accommodate walls or floors of varying thicknesses
  • Blank fittings are intended for use as abandonment plugs and for sealing openings reserved for future use. DO NOT FIELD DRILL. O-Z/Gedney™ will not be responsible for any device that has been modified in the field
