Abstract: The present invention relates to a protective cap (20) for a grease nipple. The protective cap comprises a removable cap portion (22) with an internal cavity (23) that is shaped to fit over and enclose a nipple head of the grease nipple, and comprises an attachment portion (24) that is adapted to remain attached to the grease nipple when the cap portion is removed. According to the invention, the attachment portion (24) of the protective cap (20) comprises a plurality of through holes (26, 27, 28, 29) each of which has a unique diameter.

Abstract: An article of manufacture, a quick cap device for use with a tire valve stem, which may be a pushed-to-put-on/squeezed-to-remove tire valve stem cap. Optional interior female threads and grooves may also be used with versions of the invention.

Abstract: A venting probe insertion chamber that is attached to a uniquely designed port which combines the attributes of a probe insertion chamber along with the ability to vent to atmosphere gasses that are present in piping system. This invention combines the functions of two existing products in an economically viable product. This inventive design performs all task required without the need for O-rings or sealing elements present on prior art products. Creating a simpler to manufacture and maintain device that allow for a user to obtain accurate readings of temperature and pressure while using a minimal amount of tooling. The user is able to remove the protective cap while using only a single tool to prevent dislodgement of the product from the associated port. Current state of the art can potentially place a user in harm as accidental dislodgement of their product can occur having only a single operator.

Abstract: A combination cap and plug assembly. A cap portion of the assembly is used to stop flow of material through a male coupling, and a plug portion is used to stop flow of material through a female coupling. The combination cap and plug assembly includes a tether that allows the assembly to be coupled to hose or tubing that is connected to the male and female coupling.

Abstract: A plumbing test cap has a body with a bore extending from a first end which is mountable over a stub-out having a surface engagement feature. The body has a closed second end. A retainer is carried on the body for transverse movement from a first position allowing movement of the body relative to the stub-out and a second position in which the retainer is locked to the body, in turn locking the body on the stub-out.

Abstract: The invention relates to a gas connector socket with at least one inlet port for connecting a locally fixated gas supply line, with at least one outlet port for connecting a gas connector plug, with a housing receiving the at least one outlet port, and with at least one cover located on the housing, wherein the cover has a front side visible from the outside, in which the technical object of preventing the penetration of foreign objects into the outlet port, and the access to the gas path without particular know-how, and providing a simple and very compact embodiment, is achieved by the cover having on its backside at least one locking element for interlocking the cover with an element connected to the housing and the locking element having an operating surface accessible from the outside for unlocking the cover.

Abstract: A wall bushing for an air-conditioner comprises an external pipe and an internal pipe. The cross section of the external pipe is a “sports ground” shape, and an inner circular wall of the external pipe is tangential to an outer circular wall of the internal pipe. An end of the internal pipe is connected to an air outlet port of the air conditioner, and an end of the external pipe is connected to an air inlet port.

Abstract: A cap for a fluid coupling is provided that includes a stem member adapted for insertion into the fluid coupling and a cover member connected to the stem member. The cover member includes an internal cavity sized to receive the fluid coupling such that the fluid coupling is positioned between the stem member and the cover member. The internal cavity is defined by a wall having at least one of a longitudinally extending groove and a longitudinally extending protrusion.

Abstract: The invention refers to a charge air hose for motor vehicles, comprising: a hose-shaped base member and a textile reinforcement. In a conventional charge air hose the textile reinforcement is embedded into the base member or it is arranged between two layers of the base member. A continuing dynamic load of the conventional charge air hose leads to delamination of the composite. To solve the problems known from the prior art, the invention provides a charge air hose for motor vehicles, comprising: a hose-shaped base member, a textile reinforcement arranged on the surface of the base member, wherein the hose-shaped base member is a vulcanized, elastomer-containing hose.

Abstract: Individual attachment devices are mounted to tire valve stems or wheel lug nut studs. An upper surface of the device serves as a display area for presenting display items such as promotional decals and logos. The device may also include tabs that project from the body of the attachment device. The tabs are used as display platforms that bear indicia on one of its surfaces, such as advertisements and marketing logos. A free-floating tab may be suspended away from the attachment device body by a connection means and likewise includes display items.
