Boiler Water Level Probe with skinny gasket included This probe has an overall length of at least 140mm (depending on which supplier we receive them from). We specifically buy them as long as they are available so they can be cut to length to accommodate a specific boiler's needs. Note: some machines will use a high and low water system, and the low system might require an even longer probe depending on the model of your machine. Please measure yours before ordering - if in doubt and contact us if you need a longer probe. (We also carry 255mm probes that can be used for the LOW water alarm. If you need it for this application, please specify during check out.) Standard 1/4 BSP fitting. NOTE: Although in most applications, the standard 1/4 BSP copper gasket 8F1987 is appropriate (sold separately), some probes have a recessed edge (i.e. the Elektra boilers) and a “skinnier” OD is needed such as 01171035. NOTE: When adding 1 (one) to cart, you are ordering ONLY ONE probe, which will be of the 2 different styles shown in the images.
