A conduit coupler made of intumescent material is designed for accurately coupling plastic conduits where they pass through a fire rated separation in building. The coupler has conduit receiving regions to operate ends of the coupler. The conduit receiving regions are terminated by end stops to provide exact location of the conduits with the coupler, the intumescent material of which is free to intumesce both internally and externally of the coupler. The inward intumescing blocks off the coupling while the outward intumescing blocks off the separation opening through which the coupled conduits pass.
