These are Scuba Quality O-Rings not inferior softer alternatives manufactured for other industries that are often sold to Scuba Divers.(and fail because they are not hard enough)
VITON O-Rings are suitable for use with Nitrox, O2, Trimix and Air - Supplied in a clean Zip Seal bag.
These are OEM seals from one of the UK's leading trade supplier, not cheap developing world imports made to low standards. I will refund if you are not entirely happy with the quality of the item.
