    Magnetic—Plugs with magnet attract metal debris that could otherwise damage your system.
    NPTF Thread—NPTF (Dryseal) threads are compatible with NPT threads.
    316 Stainless Steel—Fittings are the most corrosion resistant. They stand up to wet environments, just like 304 stainless steel fittings, but unlike 304 stainless steel, they will not corrode from salt water, chlorine solutions, and chemicals.

    Low-Pressure Iron and Steel Threaded Pipe Fittings with Sealant

    To prevent leaks in low-pressure lines, the male threads on these fittings have an acrylic sealant already applied for extra protection. Also known as Pressure Class 125 or 150 fittings. Made of either iron or steel, they’re best in noncorrosive environments. Even with sealant, threaded connections can be taken apart for maintenance and repair.
