The ESSENTIAL G uprights have a testing cap of their own, and 5429ZG is it. One order code covers the G1, G2, G4 and G5.Its purpose is narrow and genuinely useful. It closes off a connection while the electrical circuit is under test, so a measurement comes from a properly made circuit instead of a temporary lash-up. That is the whole value of the part. A test taken through something improvised is a test nobody can rely on, and repeating it takes longer than reaching for the right cap in the first place.Because it is a tool and not a wearing component, it lives in the service drawer next to the meter and is renewed only when lost or damaged. Any workshop regularly seeing SEBO ESSENTIAL G machines wants one to hand before the first of them arrives, since the alternative on the day is improvising around a live circuit.Keep it with the other caps in the set rather than in a general parts bin. They are distinguished by what they answer to, not by how they look on a shelf, and a cap filed in the wrong place is the same as no cap at all. Order code: 5429ZG Machines covered: ESSENTIAL G1, ESSENTIAL G2, ESSENTIAL G4, ESSENTIAL G5 Kind of part: diagnostic service cap What it does: closes off a connection during circuit testing Buying it is a decision about readiness rather than about repair. Nothing in it degrades on the shelf, and the day it is needed is rarely a day with time to order one.Confirm which ESSENTIAL G machine is on the bench before reaching for it, since the family is what determines the cap.Verify the machine family before ordering, as the caps are not interchangeable across the range. Genuine SEBO service item, dispatched in 2-5 business days.
