Steel is stronger and more durable than other metals. Zinc-plated steel has fair corrosion resistance and should be used primarily in dry environments. Chrome-plated steel has fair corrosion resistance and has a bright, shiny appearance. Nickel-plated steel has good corrosion resistance. Aluminum is lighter in weight than other metals and has good corrosion resistance. Brass is softer than other metals, so it’s easier to thread together. It has good corrosion resistance. Nickel-plated brass has better corrosion resistance than unplated brass. Nylon has good corrosion resistance, is nonmarring, and won’t scratch delicate surfaces. 303 stainless steel has very good corrosion resistance, so it’s the best choice for high-humidity environments.
NPTF (Dryseal) threads are compatible with NPT threads.
Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.
