A fluid-type penetrator or feed-through device particularly adapted for conveying an optical fiber in a fiber optic signaling arrangement through an interface wall separating environments of greatly different physical (especially pressure) and/or chemical properties. A clearance passage considerably larger than the optic fiber is bored through the bulkhead separating the two different environments, and a guidance sleeve having a central axial bore only slightly clearing the diameter of the optic fiber is inserted therein. Pressure plugs also containing axial clearance bores are provided at high and low pressure sides of the arrangement, the low pressure plug being inserted by means of screw threads. The high pressure plug on a corresponding side of the bulkhead is automatically forced into tighter engagement in the counterbore into which it is inserted. Both pressure plugs include sapphire orifice members which have the characteristic of providing very small clearance for inserted optic fibers. All clearances are sealed and bonded using a bubble-free, somewhat resilient bonding agent.
