Help Me Find A Bong Slider

Okay long story short i revised this thread and will make it easier for everyone to understand.

1) I dont know shit about sliders and i have a bong which requires this type of slider http://www.glass-pipes-water-bongs.com/pipes/740-pure-glass-slider-14.5-mm-joint---short.html
My current slider is broken and this is the same exact one that i have but i don't want to buy it because its cheap glass material.

2) I dont know anything about measurements related to bongs and sliders so i need a slider similar to this one. So far I only found a decent slider for a decent price which is
http://www.everyonedoesit.com/online_headshop/Roor_3_part_downtube.cfm?iProductID=1587 . Question can i use this as a slider( http://www.everyonedoesit.com/online_headshop/roor-carbon-filter-adaptor.cfm?iProductID=3522 ) or can i attach it to the slider which i listed from roor.

3) My bong is similar to this one ( http://www.glass-pipes-water-bongs.com/pipes/115-clear-glass-bong-with-curls.html ) but i have a smaller version which they don't sell any more.

4) Please helps me because im a complete nab with bongs and would never think that the slider would break after only having the bong for 2 WEEKS! >.<

You could always carve make out of brier-wood using a drill and a knife. Make it to small and wrap it in aluminum foil to make it airtight.
