A length compensator for pipelines, preferably plastic pipelines, containing two connecting components, preferably made from plastic, a compensating element made from an elastic material, preferably a thermoplastic elastomer (TPE), and a supporting pipe, wherein the compensating element is arranged between the two connecting components and the compensating element ends are connected to the connecting components, wherein the outer lateral surface of the compensating element is suitably encompassed by the inner lateral surface of the supporting pipe around its entire circumference, wherein the supporting pipe has a circular cross-sectional area and the compensating element expands and contracts exclusively in the axial direction.

A hose clamp includes an annular band and a spring liner. The spring liner includes an annular body having a central axis. The annular body includes a first body section, a second body section, and a central body section connecting the first body section and the second body section. Various methods include applying the hose clamp to a substrate.

Disclosed herein are devices, systems, and method for multi-stage, reusable coupling. Such a coupler can have a formable flow path and can include a first sealing engagement and a second sealing engagement. The first sealing engagement can be configured to provide a first seal of the coupler at a first temperature condition. The second sealing engagement can be configured to provide a second seal of the coupler at a second temperature condition that is different from the first temperature condition.

A connection system for a cryogenic tank with a tank wall formed with a first material. A connector is provided for a component to be connected to the tank. The connector is formed with a second material, and the connector is positioned on an exterior side of the tank and essentially congruent with a passage opening of the tank wall. At least one sealing element is provided, and the first and the second material have different thermal expansion coefficients. A counterpart formed with the second material is positioned on an interior side of the tank, and is connected with the connector via at least two fastening elements, such that the tank wall is clamped between the counterpart, the connector and the at least one sealing element, and a slight displaceability of the connector and the counterpart parallel to the tank wall remains to compensate for thermally induced mechanical stresses.
