SEBO Testing Cap for 1,000-Watt AUTOMATIC X4, X5 and ESSENTIAL G1, G2 — Blue

Blue is the 1,000-watt entry in SEBO's set of testing caps. Ordered as 5429BL, it covers the AUTOMATIC X4, X4 Boost and X5 alongside the ESSENTIAL G1 and G2.

On the bench the cap shuts off a connection so a circuit can be measured cleanly, which is the difference between a reading worth acting on and one that has to be taken twice. The colour is a working part of the system rather than decoration. With several machines open at once and more than one rating in the range, matching blue to a 1,000-watt machine keeps the correct cap on the correct job.

It covers a broad slice of the range in one item, which is why it tends to be the first cap a shop buys. An AUTOMATIC X4 and an ESSENTIAL G2 look nothing alike on the bench, yet both answer to this cap, and having it to hand means the diagnosis starts immediately instead of after a parts search.

• Order code: 5429BL
• Shade: blue
• Rating it answers to: 1,000 watts
• AUTOMATIC uprights: X4, X4 Boost, X5
• ESSENTIAL uprights: G1, G2
• Kind of part: diagnostic service cap

Nothing here wears out, so buying one is normally about a cap that has gone astray rather than one that has failed. Workshops taking in more SEBO work tend to buy the whole set at once for the same reason.

Store it where the shade shows. Picking the right cap by eye is the entire point of a coded set, and that only works when the caps stay together instead of scattering through a parts bin.

Check the rating stamped on the machine first, as one cap matches one wattage. Searches for a SEBO blue testing cap, an AUTOMATIC X4 service cap or an ESSENTIAL G2 diagnostic cap land on this number. Ships in 2-5 business days.
