The invention relates to a tapping fitting, having a saddle component for positioning on and cohesively connecting to a tubular component, and having a clamping device for clamping the saddle component on the tubular component, characterized in that the clamping device has a tiltable clamping lever with a sliding profile, wherein the clamping lever is mounted via the sliding profile in a bearing shell in a first peripheral portion of the saddle component, and wherein a clamping band is attached on one side to the clamping lever at a distance from a rotation axis about which the clamping lever is tiltable in the bearing shell, and on the other side to a second peripheral portion, located opposite the first peripheral portion, of the saddle component, such that in the case of a tapping fitting positioned on a tubular component, when the clamping lever is tilted, the clamping band is biased and the tapping fitting is pressed against the tubular component.

An external seal for sealing against an elbow fitting of a fluid line has an elbow clamp and a seal. The elbow clamp has a first part that is sized and shaped to engage the outer radiused curve of the elbow fitting, and a second part that engages the inner radiused curve of the elbow fitting. The first part defines a tool opening and a tool engagement profile sealingly engages a valve in axial alignment with the tool opening. A clamping member brings the first part into engagement with the outer radiused curve of the elbow fitting. The seal is adjacent to the first part of the elbow clamp in line with the tool opening and seals around the tool opening between the elbow clamp and the elbow fitting when the clamping force is applied.

A fitting for use in making a fluid connection with a pipe includes a saddle adapted to couple the fitting to the pipe. The saddle includes a body and first and second arms configured to extend at least partly around the pipe when coupling the fitting to the pipe. The fitting also includes a tap member adapted to insert at least partly into the pipe when the saddle couples the fitting to the pipe, to thereby establish the fluid connection between the fitting and the pipe. The tap member includes at least one support arm configured to moveably couple the tap member to the saddle such that the first and second arms of the saddle can be extended at least partly around the pipe prior to inserting the tap member at least partly into the pipe.

A clamp and spike combination for use in conjunction with a flexible conduit, comprising a spike including an inlet rod with a sharpened tip for penetration into the conduit, an outlet rod connected to the inlet rod, the outlet rod having a barbed tip for attachment to a tube. The bore extends through the rods from the sharpened tip to the barbed tip, whereby the spike provides a channel for the passage of fluid. Further included, a clamp including two legs extending substantially parallel with each other and spaced apart from each other by a distance, an apex portion connecting the two legs to each other so that the clamp is shaped substantially in the form of an inverted U; and an opening in the apex portion, the opening being sized to receive the inlet rod of the spike.

An expansion plug includes a first collar configured to advance as it rotates relative to a shaft, a second collar configured to move axially along the shaft without rotating, a first expanding structure, and a second expanding structure disposed in the stated order on the shaft. When the first collar is rotated in an advancement direction, opposite sides of the second expanding structure are moved closer together to expand the second expanding structure, and then opposite sides of the first expanding structure are moved closer together to expand the first expanding structure.

An adaptor device configured to provide a fluid connection into an interior of a conduit section through an access point opening through a sidewall thickness of the conduit section may include an adaptor conduit structure defining a base conduit extending from an adaptor inlet to a base conduit outlet, a conduit connector configured to couple with the conduit section, and an elbow nozzle defining an elbow conduit extending to an adaptor outlet at a distal end and further configured to expose the elbow conduit at a proximate end to the base conduit to collectively define an adaptor conduit extending between the adaptor inlet and outlet. The elbow nozzle is configured to extend through the access point opening in a first direction into the interior and to further extend to the distal end within the interior in a second direction that is different from the first direction.

A tapping sleeve for a pipe element can include first and second sleeve portions, each defining a first axial end, a second axial end, a first side end, a second side end, and an arcuate portion extending between the first side end and the second side end; the second sleeve portion hingedly secured to the first sleeve portion; and a connecting element joining the first side ends of the first and second sleeve portions; wherein the connecting element, the first side end of the first sleeve portion, and the first side end of the second sleeve portion define at least a portion of a hinge of the tapping sleeve, a position of the first sleeve portion with respect to the second sleeve portion in an assembled condition in a circumferential direction of the tapping sleeve being different between the at least two assembled conditions of the hinge.
