How do you fit this to a fire extinguisher

remove extinguisher horn with a spanner. fit regulator to coupling you have just removed the horn from, make sure to use supplied washer, tighten with spanner.

what connection is this cga320 or w21.8 and is it a uk plug as the listing and photos are conflicting with the advert?

Sorry, it should be W21.8 cylinder.We will update the information ASAP. And the W21.8 cylinder is suitable for EU plug.
