Product Description
Dust protection cap for DIN SCUBA diving regulators. Works for 200 and 300 Bar threads. It has a lip on the inside that sits against the metal ring around the O-ring, so that the high pressure side / O-ring are free when the cap is on, to avoid contamination of O2 cleaned equipment. It is not meant to be water tight, so do not immerse your regulators with the cap on and expect them to not get flooded. It has a loop so you can attach it to things - don't attach it to your regulator though, as it will get wet during the dive and transfer water into the high pressure inlet.
