No Plug or Socket fitted.

The Vac Connector (vacuum breach unit) consists of a round, chamfered edge, aluminium base; a steel upper body and a high temperature silicone washer. The washer is retained on the underside of the steel body. The aluminium base (which has a female ¼" BSPP thread) is placed immediately on top of the breather fabric and under the bagging film. The steel body (which has a male ¼" BSPP thread on the underside) is aligned with the aluminium base and is screwed into the base whilst self-cutting through the vacuum bagging film.

Fitted with ¼" BSPP brass female vacuum socket (with viton seals)

The VAC-Connector fitted with a female vacuum socket  is a much less common configuration - the additional weight of the socket over that of the plug can impart a stress on the bagging film. However, this configuration is sometimes used to clearly identify where a vacuum monitor line will be attached.

(Available with a stainless steel socket in lieu of brass if required).
