This is a 2.4mm gas lense to suit a size 9 or 20 torch.
If you aren't sure which gas lens you have, you can measure across the small diameter thread. If you measure 8mm you already have a size 9 or 20 torch and this item will fit. If you have a size 17-18-26 you will need a #17 torch kit to adapt it which it listed in our products page.
