Square sealing cord (for boilers and furnace)

All equipment installed at consumer heating points, as well as internal heat pipelines and heating systems, must be inspected and repaired at the end of the heating season. Valves, valves and taps, including three-way valves, must be repaired and printed, and those that are faulty must be replaced. In the seals of the valves, fiberglass cords should be placed on top of the asbestos in special grooves designated for this purpose. These sealing cords are widely used in perolysis, solid fuel boilers and fireplaces. Thicknesses from 6mm to 26mm
