Solenoid External Thread Cap

Solenoid External Thread Cap   Dive Rite #DRT27-3   The Solenoid External Thread Cap is a stainless steel cap that covers the oxygen inlet. It serves two purposes: to protect the oxygen inlet’s threads when traveling and to prevent contaminants from entering the solenoid system. They are especially useful to those divers who reside close to a saltwater environment, because long exposures to ocean air could potentially corrode solenoids.
