Description

This threaded dust cap for Apeks DIN (aka G 5/8) regulators is designed to reproduce the sealing surface of a DIN valve. This seals the connector when screwed to the DIN fitting thus debris and moisture is prevented from entering the DIN orifice of the regulator as well as protecting the threads. The cap has a unique method to store an included spare oxygen compatible small DIN O-ring suitable for use with Apeks first stages. This less common size #111 O-ring better fits the slightly smaller o-ring groove of Apeks, Atomic, and Scubapro brand DIN connectors, see the discussion in our TekTip below. Both the Apeks branded cap and oxygen compatible spare O-ring are BLACK color

Best practice when rinsing regulators in fresh water is to do so while the regulator is pressurized. This cap will make a tight seal with the DIN o-ring in the regulator first stage DIN inlet, such that the cap is suitable for sealing the first stage inlet when you wish to gently spray fresh water on the regulator to rinse. Regardless, avoid submerging an entire unpressurized regulator including the second stages in a dunk tank or rinse bucket as in some circumstances that can allow water to enter through the second stages and if not immediately blown out the moisture can travel up the hoses in to the first stage.
