BIRNS® Size "P25N" (Penetrators)
BIRNS penetrators transmit electrical power/signal through a pressure boandary, decrease the complexity of electrical systems, and reduce dependence on operator skill. NPT Penetrators have tapered "pipe" threads and are widely used on diving bells and decompression chambers. BIRNS NPT Penetrators are made with AISI 316 stainless steel shells, passivated per QQ-P-35 type VI. They are rated for use up to 80º C (176º F) when fabricated with neoprene (polychloroprene) cable jackets, or up to 95º C (203º F) with optional CSPE cable jackets.
