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.
