Cups are available in 1-7/8", 2-1/4", and 2-3/4" sizes. These cups work in worn barrels with no problem!

For all cylinders handling water, fuels, chemicals, air, or gas. Perma cups are made of a special synthetic elastomer that has no equal in abrasive resistance. The rubber-like material is the toughest and strongest elastic material known to man. Tests made of working valves in cylinders with a sand slurry of very sharp sand indicates that perma-cups will outlast any leather cup 10-1. Less friction means water pumped in less wind. Cylinders can last three times longer. It is not necessary to tighten down your brass cage so tight that the three cups distort. Hand tight or a little better than hand tight is all that is needed. Eliminate down time!!!
