Claim:
An electrical connection apparatus comprising: (a) at least one stackable block, wherein each stackable block is operably coupleable to another stackable block; (b) at least one pin receiving portion defined by an inner wall within the at least one stackable block; (c) at least one electrical connection contact comprising a first portion disposed within the at least one pin receiving portion of the at least one stackable block, the first portion for receiving a pin, and a second portion disposed at a location exterior to the stackable block, wherein the first portion and the second portion integrally form the at least one electrical connection contact; and (d) a fluid seal arranged in the stackable block adjacent to the electrical connection contact, the fluid seal comprising: (i) a seal tube defining a pin receiving portion for receiving the pin; and (ii) a cinch for reducing the diameter of the seal tube around the pin; wherein when the diameter of the seal tube is reduced around a diameter of the pin, the seal tube fluidly isolates the at least one electrical connection contact associated with one stackable block from another electrical connection contact associated with the another stackable block.
