Abstract
A re-enterable seal (25) for sealing an elongate object (16) passing through a barrier (24) between two environments (53, 54) includes an invertible enclosing member (30) containing a sealant (40). The sealant (40) is adhered to the inside surface (31) of the enclosing member (30). During insertion of the elongate member (16), the enclosing member (30) is inverted inside-out, with the sealant remaining on the inside surface (31) (now positioned outside the enclosing member). The elongate member (16) is then pulled back, causing the enclosing member (30) to re-invert, and bringing the sealant (40) into sealing compression against the elongate member (16).
