Up Aqua’s new simple regulator is the latest solution using both the disposable cartridge and paintball bottles. It has combined both designs into one unit. Depending on which bottle you are using at the time, you can simply unscrew the adapter for paintball bottles and switch to the disposable cartridge, and vice versa. The disposable cartridges are UA-141, A-141, UA-142, or A-142 for ordering purposes. Important Info: Use teflon tape on any fitting that does not seal with a gasket or o-ring. Warranty Info: All regulators shall be covered by a 90 day limited manufacturer's warranty from date of purchase.
