GF reinforced technopolymer delayers specifically designed to solve the draft problems due to the wear of the tappet plate or to an imperfect compatibility between aftermarket spare parts installed on your replica.

These delayers are produced by plastic injection molding method and they collect all the advantages of the other types on the market:

- they allow a greater retreat of the tappet plate as round metal ones
- they anticipate the opening and postpone the closure of the air nozzle like those of similar form

Being made of GF reinforced technopolymer they can be easily modified to meet particular needs.

Set composed of three pieces.
