Geocel Plumba Flue 310ml High Temp Silicone Sealant Black 2902444/C05

This 310ml black high temperature silicone sealant is intended for sealing joints and gaps exposed to elevated heat, such as those found in flue pipes, stoves, and appliance surrounds. Its dark finish blends in with typical fittings, providing a discreet joint where appearance matters on site.

Suitable for use during plumbing, heating, and general building works, the sealant is often applied during installation or repair of systems where heat and movement may affect traditional sealants. It is dispensed easily with a standard caulking gun, allowing controlled application both indoors and in exterior areas subject to moisture.
