Abstract: An integral ring shaped seal of flexible elastomer material includes one or more oppositely peripherally disposed ridges and grooves for effecting sealing between telescoping male and female conduits, useful in air conditioning and heating ducts for commercial and military aircraft. The ridge(s) is absorbed into the flexible seal body due to compensation provided by the groove(s) which also disappears, thereby insuring sealing against vapor and fluid leakage throughout a broad temperature and pressure range.

Abstract: The shroud is formed from sheet material and is cylindrical in shape. A plurality of spacers are associated with the sheet material. These spacers are designed to engage the outer surface of a duct to hold the cylindrical sheet material in radially outwardly-spaced relationship to the duct, defining thereby an insulating air gap between the outer surface of the duct and the shroud. The angular space between the spacers serves as gas channels to permit gas to flow between the shroud and the outer surface of the duct, along the length of the duct. The shroud has a straight axially-extending slot along its entire length for easy removal from a duct. An axially-extending edge receiving pocket is formed on the shroud adjacent to the slot for receiving the adjacent longitudinally extending edge of the slot to hold the shroud in a cylindrical shape and to provide a gas tight closure for the slot.

Abstract: An integral ring-shaped seal adapted to be carried at the end of a connector housing and provide two spaced-apart sealing portions, said two spaced-apart sealing portions being connected by a web, and said two spaced-apart sealing portions together with said web providing therebetween an opening adapted to receive a flange located in proximity to the end of the connector housing, at least one of said two spaced-apart sealing portions having a cut-out axially disposed away from said opening to provide increased resiliency and wear resistance.
