What it is

The Alpha 1.029221 is a straight gas service cock with a 1 inch connection, used on Alpha gas boiler installations. It provides a means of isolating the gas supply to the appliance for servicing and maintenance. It is listed by the manufacturer under part number 1.029221.

Signs this part needs replacing

  • The spindle is stiff, seized or will not turn through its full travel.
  • A gas smell or detectable leak is present at the gland or body.
  • The valve weeps or shows corrosion around the body or connections.
  • The valve no longer isolates the gas supply fully when closed.
  • The operating handle or spindle is damaged or broken.

Before you order

  • Confirm your appliance model against the fit list above.
  • Check the existing valve is a straight pattern and not an angled equivalent.
  • Verify the connection size required is 1 inch.
  • Confirm whether the installation is LPG or natural gas, as listed models differ.
