SAE (Standards for Automotive Engineers) threads are more common in industrial and automotive applications. For electrical feedthroughs, the preferred interface is an O-ring seal design versus a metal-to-metal seal with a tapered thread. SAE feedthroughs have an O-ring is installed between the thread and hex of the feedthrough. Straight threads engage with the mating surface and seal between the hex housing, O-ring, and mating surface. SAE feedthroughs can typically operate at higher pressures than NPT threads, but require more mating surface wall thickness to manage the pressure. Metric threads are also available in tapered and straight thread applications. The same materials and sealing methods are also available.
Douglas Electrical Components can hermetically seal a variety of electrical connections in an SAE configuration. Hermetic terminal seals are very popular for transmitting power in compressor and motor applications, utilizing SAE threads. Douglas offers a variety of standard configurations within the StudSeal motor terminal line.
Connectors, wires and circuits are also available in SAE feedthrough designs. Douglas can combine various types of electrical connections to simplify installation or retrofit existing designs. We source high quality electrical components to include in the design.
