Abstract: 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.

Abstract: An apparatus for isolating elbow fittings includes a fluid containing elbow housing with cooperating components. The elbow housing has a first opening for a first branch of an elbow, a second opening for a second branch of an elbow and a tool insertion opening in axial alignment with the first opening. The cooperating components of the elbow housing are secured around an elbow. A seal seals the first opening, the second opening, and the cooperating components. An isolation valve controls the tool insertion opening.

Abstract: A pressurized fluid line servicing tool assembly consists of a tool insertion adaptor, a cap removal tool and a plug setting tool. The tool insertion adaptor connects to a pipe of a pressurized fluid line and enables tools to be inserted and removed without releasing pressurized fluids, such as natural gas, to atmosphere. It has a tool insertion chamber which is divided into an upstream portion and a downstream portion by a valve. The cap removal tool connects to the tool insertion adaptor to enable service personnel to pass a cap removal wrench through the valve to remove a cap from an end of the pipe of the pressurized fluid line. The plug setting tool connects to the tool insertion adaptor to enable service personnel to pass a torque settable plug through the valve to set a plug into the end of the pipe.
