WP9 / WP20 Back Cap O ring
If you have a gas leak from your back cap then instead of replacing the whole back cap why not just replace the O ring?
This particular O ring is for the WP9 and WP20 torches. The WP17 types have a slightly larger diameter and will not fit.
The Binzel original part number for this item is: BIN98W77. Others may call it just 98W77.
All back caps that this O ring will fit are listed in the related products below.
Important Note
Please note that "O" rings are considered as a "perishable item" and cannot therefore be returned for credit should you order the wrong item.
