Abstract:
A pressure control device (10) for sealing a conduit (12) is described. The pressure control device (10) comprises a seal element (14) comprising an elastomer, the seal element (14) defining a seal element external surface portion (20), the seal element external surface portion (20) defining an external perimeter. The external perimeter is adapted to increase as an environmental temperature increases, such that, in use, an increase in the environmental temperature can move the seal element external surface portion 20 into engagement with the conduit (12) or, once engaged with the conduit or if already engaged with the conduit, can create an improved seal with the conduit.
