ABSTRACT:
A kit for use in forming pressure blocks in a cable including a fluid injector with a pressurizing plunger providing a discrete amount of pressure block forming material, such as self-setting plastic, a tap fitting with a fluid inlet port providing access to the interior of the cable, and a valve comprising a housing and a closure member movably mounted to the housing, the closure member including first, second, and third sections. The first valve section includes means establishing free fluid communication between the injector and the fluid port, the second section including means sealing the passage portions from one another and from the exterior, and the third section including means communicating the fluid injector to the exterior. The valve prevents creation of a vacuum internal of the fluid injector which hinders the withdrawal of the plunger in the fluid injector while coupled to the tap fitting. The valve also blocks just injected fluid material maintaining it within the cable and under pressure, which permits the subsequent injection of additional fluid material without loss of pressure interior of the cable.
