BOSS Retrofit Fire Collars prevent the spread of fire where PVC and PE plumbing pipes penetrate concrete fire walls and floors. Also for use on PP-R pipes, and polybutylene pipes.
Boss Fire Collars are suitable for on walls and floors. With the addition of the optional ‘click on’ flange oversize holes may be accommodated.
Unlike intumescent assisted mechanical damper type fire collars, Boss Fire Collars contain no fusible links or moving parts to require servicing. As the fire stopping intumescent material in our product is around the outside of the uninterrupted pipe it does not affect the performance of the pipe.
