What it is
The Alpha 3/4 inch gas cock union (part 6.5615521) is a gas isolation fitting used on Alpha Ocean Style and Ocean Secura gas boilers. It forms the gas inlet connection at the appliance, allowing the gas supply to be isolated for servicing and maintenance. Manufacturer data also lists this item as an 18 mm gas inlet elbow.
Signs this part needs replacing
- Gas smell around the boiler gas inlet connection
- Visible corrosion, verdigris or staining at the union
- Weeping or bubbling when leak-detection fluid is applied to the joint
- Stiff, seized or rounded valve spindle that will not isolate the gas supply
- Difficulty achieving a gas-tight seal when reconnecting the gas supply
Before you order
- Confirm your boiler model and GC number against the fitment list above
- Check the existing gas cock union is a 3/4 inch fitting matching part 6.5615521
- Check the union orientation and inlet arrangement on the appliance before fitting
- Gas work must be carried out by a Gas Safe registered engineer
