A valve block may be provided with a plurality of flow bores within a body the valve block. In addition, valve block may have a plurality of openings opening at an outer surface of the valve block and in fluid communication with the plurality of flow bores. Further, a blind plug may be within at least one of the openings. The blind may include a cap coupled to an inner surface of the at least one opening and a plug having a first end face in contact with the cap and a second end face extending into the flow bore. Furthermore, the blind plug may seal the at least one opening from a surrounding environment.

An apparatus for sealing an opening in a metal sheath surrounding an insulated pipe is provided, the apparatus including a base comprising an outer flange securable within the opening, and defining an inner passage therethrough, the base having an annular ridge extending into the inner passage; a flexible waterproof body positionable within the inner passage, the body having a periphery therearound and a groove located within the periphery adapted to engage around the annular ridge; and a flexible metal element within the base.

A hole plug includes: a tube-shaped outer peripheral wall configured to be inserted into an attachment hole formed in an attachment-target member; a blocking portion-close off the inside of the outer peripheral wall; a ring-shaped flange that juts out toward a radial direction outer side of the outer peripheral wall from an end portion of the outer peripheral wall on an opposite side from an insertion direction so as to cover a location surrounding the attachment hole; a hook portion engage with an edge of the attachment hole; and a plurality of recess portions that are formed at a front face of a base end portion of the flange at intervals around a circumferential direction of the flange, each of the recess portions including a bottom portion with a planar face profile or a curved face profile.

A sealing cap for a compressor is made of an elastically-deformable material and includes a plug portion, a bolt insertion portion, a tab portion, and a plate-like body portion. The plug portion is to be inserted into a fluid port of a compressor to plug the fluid port. The plate-like body portion integrally joins the plug portion, the bolt insertion portion, and the tab portion. The bolt insertion portion extends from a front surface of the body portion. The tab portion is formed on the front surface of the body portion. The plug portion is projectingly formed on a rear surface of the body portion. The tab portion includes a ring having an annular shape, and is located opposite to the bolt insertion portion across the plug portion. The ring has an opening that extends through the ring in a direction that crosses insertion direction of the plug portion.

A strut mount cap is provided on an upper surface of a strut mount, and is configured to close a hole housing a fastening component for the strut mount and a shock absorber. The strut mount cap includes a cap body configured to close the hole, an annular water stop lip provided on an outer periphery of the cap body and in elastic contact with the upper surface of the strut mount to prevent water from entering the hole, a press-fit tube provided on a back side of the cap body and held on an inner peripheral surface of the hole by being press-fitted into the hole, and a check valve configured to open the hole when an internal pressure in the hole is equal to or higher than a preset pressure, and close the hole when the internal pressure is lower than the preset pressure.

A sealing lid for sealing a compartment of a supercapacitor housing electrodes and electrolytic material is described, the supercapacitor comprises: a casing internally defining the compartment and having a longitudinal axis, a side wall extending around the longitudinal axis, an axial bottom wall and an axial opening for accessing to the compartment arranged on an axially opposite side of the side wall with respect to the end wall; and at least one terminal electrically connected to one of the electrodes and protruding outside the compartment through the axial opening; the lid is adapted to close the axial opening and comprises an elastomeric element having: an internal through-hole adapted to receive the terminal and delimited by an internal wall adapted to cooperate in fluid-tight contact with the terminal; and a peripheral wall adapted to cooperate in fluid-tight contact with the side wall.
