Internal o rings for Theoben gas ram models with the H.E. system (e.g. Fenman, Evolution).

These are only suitable for the models with the H.E. system (not all have this) If it does this will be stamped, generally on the top of the barrel.

Kit now updated to include different versions of the HE system (therefore will have more seals than required) – just use the ones that match those coming off.

Please note picture is currently generic.

If you have an Eliminator with the H.E. system please contact us first.
