What it is
The Potterton 10 Thermocord Gasket is a 10 mm thermocord sealing gasket supplied by Potterton Commercial for use in Potterton Commercial NXR3I gas boilers. It is a boiler sealing component, listed by the manufacturer under gas boiler spares. The gasket forms a seal at the joint it is fitted to, preventing leakage in service.
Signs this part needs replacing
- Visible water or gas traces weeping from the sealed joint
- Gasket cord hardened, brittle or cracking when handled
- Cord flattened or deformed so it no longer fills the joint
- Gasket damaged or displaced during a strip-down or service
- Recurring leaks at the same joint after reassembly
Before you order
- Confirm the appliance is a Potterton Commercial NXR3I and note the section count
- Check the existing gasket cord diameter against the 10 mm specification
- Verify the part number 5140648 against the number on the existing component or the manufacturer's parts list
- Isolate the gas and water supplies and follow the manufacturer's procedure before removing the gasket
