After anaerobic water in the water disappears when the glue, glue the polymer body to rely on the tension between them, the two objects together tightly. In the use of glue, the glue will make excessive amount of glue in each polymer body crowded together; not produce good body tension between the polymer. Polymer material crowding each other, thereby forming with each other can not be the most attractive. Meanwhile, the body of water between the polymer is not easily volatilized. This is why in the bonding process, "film thicker pipe diameters bigger gap between the pipe and the interface will be.

   Similarly Sch40 anaerobic water pipe 8 for "slow than a high viscosity glue is used in a pipe" Pipeline longer low viscosity glue, because the pipe diameter increases, the gap is increased, the glue requires more to fill these gaps. On many occasions, anaerobic material called "red or blue material." For thread locking agent, the color indicates strength. Typically, high intensity red, blue indicates moderate, purple indicates a low strength. Other colors respectively corresponding to the intensity range.
