Factors that affect pipe pressure limitations include the pipe size, schedule and material. The pipe size is the diameter of the pipe. The schedule is the thickness of the pipe walls, with higher numbers indicating thicker pipes. Thicker pipes are able to withstand more pressure.

Common pipe materials include plastic, stainless steel and carbon steel. Pipes made of metal tend to be able to handle higher air pressure and temperatures than plastic pipes.
