Pepper Pot Flue Terminal — 275mm Buff (Clay Chimney Vent)
This Buff clay terminal is designed to ventilate redundant flues so the stack can breathe. Gentle airflow helps reduce moisture, odours and condensation in disused chimneys. The 275 mm nominal size suits common 7″–7.5″ set-ups—please check your pot and flue dimensions before ordering.
Why choose this terracotta pepper pot chimney terminal
- Purpose: Vent a redundant flue to keep the stack breathing—vent, don’t seal.
- Finish: Warm Buff tone for heritage and period roofs.
- Material: Durable vitrified clay built for UK weather.
- Fitment: Bed and point to the existing pot with external-grade mortar.
- Not for live flues: Use an appliance-specific cowl for fires, stoves, gas or oil.
For active flues, compare chimney cowls at Hot Box Stoves. To fine-tune openings on this style, see pepper pot inserts.

Installation & compliance — pepper pot flue terminal
Installation steps
- Confirm the flue is redundant. Live flues require a fuel/appliance-specific cowl.
- Check the stack is sound and the pot secure; prepare a clean, level bed.
- Bed the terminal on suitable external-grade mortar; align and point neatly.
- Provide through-ventilation at the base (air brick or vent plate) so the flue can breathe.
- Re-check after high winds and during routine roof maintenance.
Compliance notes
For redundant stacks, aim for controlled ventilation rather than a sealed termination. For general guidance on chimneys, flues and ventilation, see UK Approved Document J. Conservation settings may require profiles sympathetic to local character.
FAQs
Is 275mm the size of the pot or the flue?
Use the 275mm model where your chimney pot/flue arrangement corresponds to this nominal size. If unsure, measure the pot throat and existing flue or check with your sweep/installer. Explore other sizes in the Pepper Pots category.
Can I use this on a working fire or stove?
No. This profile is for disused flues. For live appliances, choose a cowl specified for the fuel and chimney system — compare options at Hot Box Stoves.
Will it keep all rain out?
It reduces direct rain entry while allowing airflow. Some incidental moisture is normal and helps the stack ventilate. For live flues needing rain/bird protection, see bird/rain cowls.
