Brahma Electrode RS27T6 12429133

Brahma RS27T6 electrode, SKU 12429133, is an ionization and ignition electrode from Italy. It has a total length of 187 mm, with a ceramic insulator and a metal rod length of 129 mm. The electrode features a movable clamp for mounting and is resistant to soot. It is designed for use in burner systems, serving either to ignite the fuel-air mixture or to detect flame presence.

When selecting a replacement electrode of this type, verify the total length, rod length, and bend against the original. The ceramic insulator diameter and length must match the burner's combustion head geometry. The mounting flange arrangement and clamp type (fixed or movable) must be compatible. Always compare the electrode's physical dimensions and spark gap (if applicable) with the original before installation.

Typical failures include erosion of the electrode tip, cracking of the ceramic insulator, and soot build-up that can short the signal. A drifting spark gap may cause ignition failure or intermittent operation. If the electrode fails, the burner may not ignite or may lose flame signal, leading to safety shutdown.
