Quelfire QWR125 Intumescent Fire Collar 125mm

The Quelfire QWR125 is an intumescent fire collar for 125mm plastic pipe and round plastic ventilation duct, including Domus EasiPipe 125. It replaces the Domus DFSV125 fire sleeve, which is no longer available.A pressed stainless steel shell holds a graphite-based intumescent liner. In a fire the liner expands, crushes the softening pipe and seals the opening with a hard char, giving up to 240 minutes (EI 240) fire resistance in tested configurations. Built-in lugs fix it to the wall, floor or ceiling, and it can be retrofitted around existing pipework.For a vertical pipe, fit one collar to the underside of the floor. For a pipe through a wall, fit one collar on each side. Tested to BS EN 1366-3 and classified to EN 13501-2.
