Go Back

The Filobox cable joint kit is suitable for sealing underground cable connections. The Filobox T40 + Filogel contains a non-hazardous 2K polybutadiene resin. The Filogel resin cures to a soft and non-sticky sealing gel which creates a durable seal around the cable connection. Filogel provides easy re-enterability.
