Water Container Screw Cap DIN 51, Graphite

This graphite screw cap closes the filler opening of water containers and jerry cans with a DIN 51 neck. Fit it in place of a cap that has gone missing or been damaged, or keep it with the container as a spare, so one lost cap does not put the whole container out of use.

The cap is moulded in polypropylene, as the PP recycling mark on its underside shows, and finished in a dark graphite grey. Its flat top is closed, with no port or opening. Fine knurling with raised vertical ribs runs around the side, giving a firm hold when the cap is turned by hand, and a wider collar sits at the base.

Inside, a white sealing ring is seated in the channel between the thread and the centre of the cap. As the cap is screwed down, the ring meets the rim of the container neck and closes the filler opening.

DIN 51 is a neck size of its own: containers with a DIN 61 neck need a DIN 61 cap, so check the neck of your container before ordering. The cap suits anyone who carries water in a DIN 51 container, from campers and campervan travellers to people heading off-road or away on holiday, anglers, hunters and work crews who keep a water container in a service or workshop van. The container itself is not part of the order; only the cap is supplied.
