Plastic Ducting Reducer / Adaptor
Plastic ducting reducer / adaptor allows you to convert a larger duct to a smaller duct with ease
125mm to 100mm Reducer / Adaptor R125100P
- On one side there is a 125mm female socket. This will fill fit over male fittings (such as bends, connectors, etc) but it will not fit directly onto ducting without using a male connector
- On the other side there is a 100mm male spigot, this allows you to be able to install into ducting or flexible ducting, it will not connect to a fitting without using a short piece of ducting
150mm to 100mm Reducer / Adaptor R150100P
- On one side there is a 150mm female socket. This will fill fit over male fittings (such as bends, connectors, etc) but it will not fit directly onto ducting without using a male connector
- On the other side there is a 100mm male spigot, this allows you to be able to install into ducting or flexible ducting, it will not connect to a fitting without using a short piece of ducting
150mm to 125mm Reducer / Adaptor R150125P
- On one side there is a 150mm female socket. This will fill fit over male fittings (such as bends, connectors, etc) but it will not fit directly onto ducting without using a male connector
- On the other side there is a 125mm male spigot, this allows you to be able to install into ducting or flexible ducting, it will not connect to a fitting without using a short piece of ducting
200mm to 150mm Reducer / Adaptor R200150P
- On one side there is a 200mm female socket. This will fill fit over male fittings (such as bends, connectors, etc) but it will not fit directly onto ducting without using a male connector
- On the other side there is a 150mm male spigot, this allows you to be able to install into ducting or flexible ducting, it will not connect to a fitting without using a short piece of ducting

Compatibility
Plastic ducting reducer / adaptors are compatible with most manufactures
Performance
Solid Rigid ducting is suitable for use in all buildings to provide superior airflow performance vs. comparative size rectangular or flexible PVC or Aluminium duct. Suitable to use in compliance with Part F Building Regulations
Installation
To provide the best performance in airtightness and durability we recommend You provide greater mechanical strength to a joint by using a combination of plastic ducting sealant and aluminium duct sealing tape
- Apply duct sealant to the male fitting
- Push together
- Apply aluminium duct sealing tape over joint
Alternatively, you can use self-sealing fittings that speed up the time taken by up to 70% and can be easily dismantled
Insulation of Ductwork
It is important that any ducting located in a cold area (e.g. loft space) to be insulated. The insulation needs to be the equivalent of 25mm thick and have a thermal conductivity of 0.04W/(m.k) or less.
This ensures that condensation doesn’t form due to the difference in air temperature inside the duct when compared to the air temperature in the cold space.
If you don’t have a loft space there is still a need for insulated ducting on the intake and exhaust legs, as they will be carrying cold air in a warm space. The level of insulation can be achieved by wrapping PVC duct in a layer of 25mm duct wrap that has a silver foil face on a 25mm rockwool
It is also worth noting that foil wrap with air bubbles (bubble wrap) is no longer applicable in building control regulations
Sizes
PVC ducting reducers / adaptors are available in four different sizes:
- 125mm to 100mm
- 150mm to 100mm
- 150mm o 125mm
- 200mm to 150mm
If you require larger ductwork we recommend you use metal Spiral ducting and fittings due to superior strength
