ABSTRACT:
A service tool for a valve and visual low pressure indicating assembly for a pressurized container and particularly of a type adapted for operative association with a pneumatic vehicle tire, while being applicable generally to other containers enclosing a fluid under pressure. The pressure indicating valve and assembly serves as means for insertion, or removal, of fluid under pressure from the container, but further, and of substantial significance, serves to externally visually indicate a condition of low or diminished fluid pressure within a tire or other container. The new pressure indicating valve assembly constitutes a replacement for known valve structures and, due to an entirely different construction and operation, creates a need for the tool structure of the present invention, to implement and facilitate servicing of the novel pressure indicating valve structure assembly.
