Dimensions & Drawings
The Elastomeric End Seal, in a specially formulated rubber compound, holds pressure at the required level during the CCV/VCV/SSCV continuous-vulcanization curing process and holds the cable tight through the production run, on both water- and gas-cooled lines.
The sealing unit is opened and closed hydraulically from the control panel, and locked or unlocked manually. GHSGs ship with a factory-applied hot-melt adhesive that seals to the wire and cable jacket.
