Cadac Threaded Cartridge Regulator - EN417 Gas Cartridge Regulator for Your Cadac LP BBQ This is a super lightweight, screw on gas regulator that attaches to a standard EN417 threaded cartridge and hooks up to your Cadac LP BBQ via a standard thread connection. You get an 85cm hose and a tailpiece with a handwheel on it, making it perfect for the 2 Cook 3 Classic Stove and Safari Chef 30 LP Deluxe. Just one thing to watch - it won't work with BBQs that have a quick release (QR) connection built-in. For those quick little trips out - a picnic, a day at the beach or a short camping stay - a single EN417 threaded cartridge and this tidy regulator is all you need. Just chuck the regulator onto the cartridge, give the tailpiece a quick hand-tighten to the BBQ, and you're ready to fire up your BBQ - no nasty gas cylinder to lug around, no faffing about wit
