KYL12 Pepper Pot Flue Terminal — 185mm Spigot, Terracotta Clay
A traditional terracotta clay pepper pot terminal designed to ventilate redundant and disused chimney flues while helping reduce direct rain entry at the top of the chimney.
Before ordering, measure the internal diameter of the opening at the top of your existing chimney pot and confirm that it can accommodate the approximately 185 mm outside-diameter spigot.
Vent, don’t seal — keep the redundant chimney breathing.
Why choose the KYL12 terracotta pepper pot?
Traditional clay appearance, straightforward fitment and controlled ventilation for redundant chimney flues.
The lower insert section has an approximately 185 mm outside diameter.
Allows a redundant or disused chimney to remain ventilated rather than being completely sealed.
A classic clay appearance suited to traditional, period and heritage-style properties.
The pepper pot profile helps reduce direct rain entry while retaining ventilation.
The lower spigot is inserted into the existing chimney pot and securely bedded and pointed as appropriate.
This product is not intended as the terminal for a working fire, stove, gas appliance or oil appliance.
185 mm spigot size — what should I measure?
Correctly measuring the existing chimney pot is the most important step before ordering.
- Measure the internal diameter of the opening at the top of your existing chimney pot.
- Confirm that the opening can accommodate an approximately 185 mm outside-diameter spigot.
- If the pot is tapered, irregular or weathered, measure the opening in more than one direction.
- Do not rely solely on nominal descriptions such as 7″, 7.5″ or 8″. Clay chimney pots can vary in their actual internal dimensions.

Installation guidance
Straightforward fitting principles for installation into a suitable redundant chimney pot.
Ensure that the chimney is not serving a working combustion appliance.
Measure the internal diameter and confirm that the approximately 185 mm external spigot can be accommodated.
Check that the chimney pot, flaunching, stack and surrounding masonry are secure and suitable for installation.
Position the lower section of the terminal inside the opening of the existing chimney pot.
Secure using suitable external-grade mortar and finish neatly around the junction.
Ensure the ventilation openings remain unobstructed and retain appropriate low-level ventilation to the redundant flue.
For redundant stacks, controlled ventilation is generally preferable to completely sealing the flue. A chimney serving a working combustion appliance requires a terminal appropriate to the appliance, fuel and chimney system.
General UK guidance relating to chimneys, flues and combustion appliances can be found in Approved Document J . Listed buildings and properties in conservation areas may also require chimney terminals and external alterations that are sympathetic to the character of the building.
Chimney-level work involves significant work-at-height risks and should only be undertaken using appropriate access and safety arrangements.
Frequently asked questions
Common questions about KYL12 sizing, suitability and installation.
What does the 185 mm measurement refer to?
The 185 mm measurement is the approximate outside diameter of the lower spigot. This is the section of the pepper pot terminal designed to insert inside the opening of the existing chimney pot.
What is the internal diameter of the KYL12?
The KYL12 has an approximately 150 mm internal base diameter and an approximately 185 mm external spigot diameter.
Is 185 mm the size of the chimney pot or the flue?
Neither. The 185 mm dimension describes the outside diameter of the lower insert spigot. Measure the internal diameter of your existing chimney pot opening to determine whether the terminal will fit.
Should I measure the inside or outside of my chimney pot?
Measure the inside diameter of the opening at the top of the existing chimney pot. This is the opening into which the approximately 185 mm external spigot is inserted.
My chimney pot is described as 7 inches. Will the KYL12 fit?
Do not order solely from a nominal 7″, 7.5″ or 8″ description. Clay chimney pots can vary in wall thickness, taper and actual internal dimensions. Measure the actual internal opening and compare it with the approximately 185 mm external spigot before ordering.
How large is the top of the pepper pot?
The KYL12 has an approximately 300 mm top diameter and an approximately 200 mm overall height.
Can this terminal be used on a working fire or wood-burning stove?
No. The KYL12 pepper pot is intended for redundant or disused flues. A working stove, open fire or other combustion appliance requires a terminal or chimney cowl suitable for the particular appliance, fuel and flue system.
Does a redundant chimney need ventilation?
In many situations it is beneficial to retain controlled ventilation through a redundant flue rather than completely sealing it. Ventilation can help disperse moisture, condensation and stale air within the chimney.
Will the pepper pot keep all rain out?
The covered profile helps reduce direct rainfall entering the chimney while retaining ventilation. It should not be regarded as creating a completely watertight seal.
What if my chimney pot opening is only slightly larger than 185 mm?
Measure carefully before ordering. The existing opening must be sufficiently large for the approximately 185 mm outside-diameter spigot to enter and for the terminal to be installed securely.
185 mm Spigot Terracotta Pepper Pot
Check before buying: confirm that the internal opening of your existing chimney pot can accommodate an approximately 185 mm outside-diameter spigot.
