Sealing caps and method for manufacturing such sealing caps are presented wherein the sealing cap has a body (1) with a U-shaped profile with a base (9) and a perimeter wall (7) wherein the outside of the body is coated with a layer of an elastic material (5) and wherein the base is provided with a continuous convex ridge (12) adjacent the perimeter wall.

A keg/cask seal for a keg or cask containing a beverage is disclosed. A color mark is arranged in a geometrically defined shape on a top side of the keg/cask seal. The geometrically defined color mark allows a conclusion to be drawn about the time lapsed since the keg/cask seal was installed.

A vacuum chamber system is provided which includes a vacuum chamber body, a lid, and an elastomeric sealing element. The elastomeric sealing may be positioned about the lid. The elastomeric sealing element includes a body having a base portion positioned between a first arm and a second arm. Each of the first and second arms have inner lid contacting surfaces and outer surfaces. The elastomeric sealing element has a generally U-shaped transverse cross-section defined by the base portion and the first and second arms, and is generally reversible between first and second configurations.

A cover assembly for restricting access to an access opening includes a cover member and a flexible member. The cover member includes a central covering portion surrounded by an outer peripheral collar portion defining a passage, and a tab affixed to the collar portion, with the tab including at least one tab aperture. The flexible member extends through the passage and has a first end extending outward of the passage and including at least one flexible member aperture, and a second end secured to the collar portion. When the first end of the flexible member is pulled, the collar portion of the cover member is constricted, and one of the at least one flexible member apertures is aligned with one of the at least one tab apertures to receive a locking member therethrough, thereby securing the collar portion in a constricted condition.

A fluid end, includes a plunger reciprocating within a first bore, the plunger increasing a pressure of a fluid within a pressure chamber. The fluid end also includes a second bore. The fluid end further includes a plug assembly associated with the second bore. The plug assembly includes a plug body positioned within the second bore. The plug assembly also includes a lock ring positioned, at least in part, within the second bore, the lock ring positioned to be driven radially outward responsive to a longitudinal force applied to the plug body.
