Birns Primum

Birns Primum connectors are designed for extremely heavy-duty use—and are trusted in some of the most rigorous underwater applications on the planet. Made of 316 stainless steel passivated per ASTM A967, or custom built with practically any material specified, they come standard with high open face pressure resistance, and are rated to 500 volts, with high-voltage or special configurations available for specific applications. These robust, versatile connectors are rated to 6,000m and designed for use with solid or oil filled cables, and tailored for the heaviest power signal, high voltage (to 3,000V) and electro-mechanical applications.
