I need a couple of those self sealing plug in airline thingies, bulkhead mounting, and the plugs to fit them, but for a vacuum line with a hose of
4mm internal diameter. RS do a range, but they seem pretty expensive for what I need. Any suggestions as to a supplier? I saw the normal 'tyre gauge' size at my local market for a couple of quid, but they're too large.- posted
