Repaired?

Last week I noted that the Plug-N-Play connector on my UltrAspire drinking bladder had broken. The part bought online arrived very promptly. But, and there always seems to be a but, it was subtly different to the broken one in that the ridged pipe part was slightly smaller diameter. I noted that the red pie is 'Big Bore' so presumably this part suits the normal piping?

Anyway this is the only part listed so I widened the push part using 2 layers of heat shrink tubing. Note that I'd already checked that the plastic wasn't damaged by hot air by testing it on the broken one.

By only placing a loop at the tip I hope to have made a firm hold and a seal for the Big Bore tubing. It was certainly a tight fit and it was only possible to fit the pipe after a fair soak in hot water.

Just needs testing now. When's the next 'long run'?
