The present invention concerns a module (1) of a seal or transition for cables or wires, which module (1) is to be placed inside a frame (10) together with one or more compression units (12). The module (1) comprises two module halves (2). Each module half comprises an outer part (3, 17, 19, 21, 23, 25, 27, 30, 33). The outer part has a straight section (3′) and two end sections (3″) at the ends of the straight section and placed perpendicular to the straight section, giving a U-form in end view. An inner part (5, 18, 20, 22, 24, 26, 28, 31, 34) is placed in a recess (4) formed between the end sections of the outer part (3, 17, 19, 21, 23, 25, 27, 30, 33). The inner part (5, 18, 20, 22, 24, 26, 28, 31, 34) has a number of layers (6).

A tubular base plate assembly has a lower surface connected to a heating system component and an upper surface. A tubular seal plate assembly is positioned above the base plate assembly upper surface having a mating surface facing the base plate assembly upper surface with a plurality of grooves therein. Sealing material is provided within the grooves. A tubular hub assembly is positioned above the seal plate assembly. A plurality of fasteners connects the seal plate assembly to the hub. A plurality of external brackets connects the seal plate assembly to the base plate assembly to secure the seal plate assembly. The sealing material forms a first gasket between the seal plate assembly and the base plate assembly. Each of the external brackets is joined to the tubular base plate assembly, so that the external brackets and the tubular base plate assembly are integral.

Grommet assembly and method for installing a grommet assembly in a penetration hole of a panel. In one embodiment, a grommet assembly is comprised of multiple parts, including end members having a diameter greater than the penetration hole, and a middle member having a diameter sized to fit within the penetration hole. Each of the members includes one or more conduit holes for a conduit that is routed through the penetration hole, and an installation slit disposed between an outer peripheral surface and a conduit hole.

A penetration fitting assembly includes a base assembly including first and second gasket halves and first and second base halves, a pipe gasket, and a cap assembly including first and second cap halves. The gasket halves each include first and second semi-annular portions, and the base halves each include a semi-annular face plate defining openings, a semi-annular groove in a front surface of the face plate, a reinforcement flange extending along an outer peripheral edge of the face plate, and a second semi-annular groove in an outer surface of the reinforcement flange. The pipe gasket includes an annular portion defining a central opening, and stem portions extending in opposite directions from the annular portion. The cap halves each include a semi-cylindrical sidewall defining a semi-annular groove, a semi-circular cap plate connected to the semi-cylindrical sidewall, and a channel defined by the semi-circular cap plate.

A penetration fitting assembly includes a pipe gasket having an annular portion defining a central opening and first and second stem portions extending in opposite directions from the annular portion, an inner ring assembly configured to surround the pipe gasket and including first and second inner ring halves, a ring gasket assembly configured to surround the inner ring assembly and including first and second ring gasket halves, a wall gasket, an outer ring assembly configured to surround the ring gasket assembly and including first and second outer ring halves, and a clamp configured to surround the outer ring assembly. When the penetration fitting assembly is installed, the outer ring assembly compresses the wall gasket against the wall of the sump, the clamp compresses the ring gasket assembly between the inner ring assembly and the outer ring assembly, and the clamp compresses the pipe gasket against the pipe or conduit.

A bulkhead passthrough connector containing a printed circuit board (PCB) for transferring electrical signals across a bulkhead to an electronic valve actuator, an electronic valve actuator configured to operate and communicate with a valve using a PCB through a bulkhead, the electronic valve actuator, and a method of assembling a bulkhead passthrough connector incorporating a PCB. The embodiments may include a passthrough partition which separates one side of the bulkhead from another. A PCB retainer may also be secured to the passthrough partition. The PCB is attached to the PCB retainer and extends from one side to another side of the bulkhead through the passthrough partition. The PCB further includes electrical paths printed on the PCB and electrical connectors located on both sides of the bulkhead to enable communication with external devices.
