Need more LP Ports on your regulator? Have a vintage regulator with fewer LP ports? This handy adapter gives you three more low-pressure female threaded ports for attachment of additional low pressure hoses such as inflator hoses for a BCD, dry suit, or additional second stages. Adapter has 3/8" male threads which will screw into any standard regulator low-pressure port. Adapter is made from corrosion-resistant marine grade chromed brass.
