What it is
The Alpha 1.5539 is a nitrile rubber O-ring with a 63 x 3 mm section, listed for the Alpha CD24S/C boiler. It provides a compression seal at a joint face, where the rubber is squeezed between two mating surfaces to stop water or gas escaping. The nitrile compound is the standard choice for sealing against oils, fuels and water in heating applications.
Before you order
- Confirm the removed O-ring measures 63 x 3 mm, as bore and cross-section both need to match.
- Check that nitrile is suitable for the medium and operating temperature at the joint being sealed.
- Cross-reference 1.5539 against the boiler's parts list before ordering.
- Inspect the mating surfaces for corrosion, scoring or old seal residue, as these will cause a new O-ring to leak.
