  conformal curved, accurately located surface) provides the sealing surface for the O-ring face seal. A threaded post bulkhead connector can also be mounted using a simple clearance through-hole and secured with a nut and washer on the interior side. A flange-mount bulkhead connector is attached to a pressure housing using machine screws that secure the connector. The screws pull the flange mount against the pressure housing, compressing the O-ring against a spot face on the pres- sure housing, and thereby making the watertight seal. Particular attention must be paid to avoid dis- similar materials and anaerobic corrosion.
