No mate it won't work - a much easier way is to leave about an inch of the rigid pipe sticking out from the jets, push some 5mm pole tubing over it and push this into a normal 6mm t-piece. No clamps needed, no extra fittings, nothing. The tubingthat peter uses is 4mm inside and 6mm outside so its a nice tight fit into the pole tubing - the 5mm pole tubing then fits nice and tightly over the 6mm t-piece.
Takes 2 mins to do and costs sweet nothing.
