When you replace and repair Tubeless Snap Tire Valve, to check the integrity of the flange. Such as flange damage, must be replaced with new parts. Replace the flange of the steps are as follows:
(1) by filing a good waste tube cut a thin, oval, its dimensions for large inner tube 160×90 (mm) for a small tube of the 140×80 (mm), and then a long rough, and along the external edge is cut into the slope. For in-use gasoline to clean after the surface had been filed, brushing glue twice, and then be dried after each brushing.
(2) from the coated fabric layer in sample cut from two elliptic slice, its dimensions for large inner tube 140×70 (mm) and 120×50 (mm) for small tubes for 120×100 (mm) and 100×40 (mm) and then brush the glue on both sides, and drying.
(3) on the rubber sheet placed on small, then put glue layer thin slices of fabric and placing symmetrical. Shall have the same distance between the sides and edges, and roller compaction.
(4) the glue layer thin slices of fabric edge inner tube covered with glue and thin Central hollow punch punching diameter 5mm small round holes.
(5) in the inner tube towards electing a no wound on the inside of the rim, with a metal brush or silicon carbide grinding wheels sanding. Size of the grinding parts, size 5mm size flange on each side;
(6) remove the tire ash, wipe the surface of the ground with gasoline, then brush two glues, and drying after each brushing.
(7) in the tube brush on glue and dry parts, paste prepared flanges and flange hole coincides with the hole on the tube, and then compacting it with the roller tube plate curing on.
(8) after curing wall of the inner tube in a flange Centre holes with an awl, and embedding from the inner tube valve; placed on the bridge-shaped pad, tighten the nut. Bridge pads should follow the tube installed.
