The present invention is directed to an apparatus mounted to a mold for injecting air into a mold cavity and removing exhaust from the mold cavity. The apparatus includes a needle rotation restrictor adapted to fit into a counter bore of a blow cylinder body, where the needle rotation restrictor has a hole through which a needle can pass. The blow cylinder body is mountable to the mold and has a conduit to the mold cavity and an interface for interfacing with the mold. The interface of the blow cylinder body has a counter-bore for containing the needle rotation restrictor. The apparatus further includes a needle having a cross-sectional shape adapted to restrict rotation within the hole of the needle rotation restrictor and passing through the conduit of the blow cylinder body. The needle rotation restrictor is rotatably positioned within the counter bore prior to engagement of the blow cylinder body with the mold.
