A sealing plug (100) for a panel opening, the plug having an axis (132) and including a head portion (110) having a first diameter larger than of the panel opening and a leg portion (120) concentric to the head portion (110) and having a second diameter shorter than the first diameter, the leg includes at least two latches (130) extending radially towards the head portion (110), and wherein the passing of the leg portion (120) and the at least two latches (130) through the panel opening causes resilient deformation of each latch (130), such that each latch (130) deforms and recovers thereby causing the panel to be retained by the at least two latches (130) and between the at least two latches (130) and the head portion (110) of the plug (100).

It is disclosed an annular seal ring adapted for use in conduit connectors. The seal ring includes an inner sealing portion and an outer sealing portion. The sealing portions are disconnected from each other allowing them to move completely freely relative to each other during operation.

The present invention relates to a sealing member for a base station antenna and a base station antenna comprising the same as well as a method and device for manufacturing the sealing member. The sealing member (2) is flexible and resilient and is configured to form a seal between an open end (5) of a radome (3) and an end cap (1) of the base station antenna. The sealing member is an elongated sealing strip having two ends, wherein the two ends of the sealing member are lappable with each other, and the sealing member has a groove extending over its entire length, which groove is defined by two side limbs and a bottom limb connecting the two side limbs of the sealing member, wherein the groove is configured to engage with an edge of the open end (5) of the radome, and wherein the sealing member is configured to be received in an annular recess of the end cap (1) and isolate an interior of the radome (3) from the environment. The sealing member can be manufactured cheaply and can be flexibly applied to base station antennas with different sizes.

A fitting provides a sealed connection in an optionally pressurized fluid conveying system. The fitting can include a face seal surface defining an annular groove having an outer wall that extends inward from the face seal surface, a floor and an inner ramp wall that extends away from the floor toward the face seal surface. The inner ramp wall can be disposed at an acute angle relative to the floor. In some applications, this angle can be about 64° to about 68°. An O-ring can be disposed in the annular groove and under tension due to being stretched over the inner ramp wall. The O-ring can exert a force radially inward toward the longitudinal axis along the inner ramp wall to thereby improve retention of the O-ring in the annular groove.

Apparatus and method contemplating a high pressure fluid end assembly having a body defining a body bore and defining a recess in the body intersecting the body bore. A closure is joined to the body and forms a sealing surface. A seal is mounted to the body in the recess and configured to extend from the recess beyond the body bore to seal against the sealing surface formed by the closure.

A multi-lobe seal for a sealing device for sealing an opening in a multi-layer wall of a fuel tank, the multi-layer wall having a layer of fuel barrier material and an opening in the multi-layer wall, the multi-lobe seal being fuel-impermeable and capable of being positioned in contact, at the opening in the multi-layer wall of the fuel tank, between the layer of fuel barrier material of the multi-layer wall of the fuel tank and a component, is disclosed. The multi-lobe seal includes, on the face capable of being in contact with the layer of fuel barrier material of the multi-layer wall, at least two protrusions, one of which leans on the layer of fuel barrier material of the multi-layer wall.

An assembly comprises

circular panel an annular body; and an elastomer.

The annular body has a panel seat surrounded by a lateral surface having a ring shaped, surrounding, outer groove bounded in a first axial direction by a first outer shoulder and bounded in an opposing, second axial direction by a second outer shoulder.

Adjoining the first outer shoulder is a guide surface having a radius monotonically increasing with separation from the first shoulder.

The circular panel has an outer lateral surface having a peripheral inner groove extending radially inwards.

The two inner shoulders have a convex contour in which the rotational axis of the circular panel extends.

The elastomer ring is clamped between both inner shoulders and both outer shoulders, whereby a shifting of the circular panel out of the annular body is prevented up to a limit loading.

A sealing structure of a humidifier includes a main structure, a left end cover, and a right end cover. The left end cover and the right end cover are arranged on left and right end faces of the main structure, respectively. A dry air inlet tube is connected to a top end face of the left end cover, and a dry air outlet tube is connected to a top end face of the right end cover. A wet air outlet tube and a wet air inlet tube are connected to left and right sides of a top end face of the main structure, respectively. Membrane tubes are arranged on an inner side of the main structure. Potting resin layers are arranged on both ends of the membrane tubes. High-temperature resistant sealant layers are arranged at connecting portions between each end cover and the main structure.

A hydraulic end assembly structure of a plunger pump, comprising a valve housing assembly, a suction gland and a suction pressing cap. The suction gland is connected to the suction pressing cap, and the suction gland is connected to the valve housing assembly through the suction packing seal assembly.

A plate heat exchanger gasket includes an elongate body and a first number of elongate projections projecting from an upper side of the body and extending along the gasket's longitudinal extension. Each projection is defined by a top and two opposing flanks extending from the top. Referring to a cross section perpendicular to the gasket longitudinal extension, for each of a second number of unsymmetrical projections of the projections, a first area defined by an outer flank of the flanks, the body upper side and a normal of the body upper side extending through the top of the unsymmetrical projection, is smaller than a second area defined by an inner flank of the flanks, the body upper side and the normal of the body upper side extending through the top of the unsymmetrical projection. This normal is displaced from a center normal of the body upper side.
