Create a professional and airtight finish around a boiler flue in seconds with FlueSnug - a time-saving solution that ensures a snug fit against the brickwork.
With a FlueSnug, there's no need to make good around a boiler flue with mortar or plaster where it exits a wall. It's so easy to fit in a 152mm core-drilled hole, and can be used on inner or outer wall faces.
Made from robust but flexible recycled polypropylene and TPE, this white FlueSnug can be safely fitted from inside the property. There's no need for ladders, scaffolding or any work at height outdoors - simply core drill the wall, slip a FlueSnug through the hole and fit the flue.

• Eliminates the need to mortar around the flue

• Designed to fit a 152mm core-drilled hole
• Easy to fit from inside - no work at height needed
• Suitable for internal and external use
• Approved by major boiler manufacturers
