Replacement Vent & Shipping Plugs

Follow

Since oil will expand and contract during normal operation, Bird oil-filled loads and attenuators use a spring-loaded vent plug to allow air flow. Before placing the load or attenuator into service, the solid shipping plug must be removed and replaced by the spring loaded vent plug. The two plugs are linked together by a short length of bead chain.
