Product Overview | 4051-XL Igniters
4051-XL igniters are available with a standard ¼ " spark plug terminal or with the aircraft style ERA connection which requires a special “4085-ERA” cable.
The 4051 Igniter is also available in extended length versions as the 4051-XL. It uses the same body as the regular 4051 with a ¾ " NPT mounting connection. This igniter was originally developed for use in the 4225 burner. See the table below and confirm in the 4225 bulletin for the correct length igniter.
Additional lengths are available as specials.
