About this item

The B&K Products 511-204HN Galvanized Coupling is engineered to deliver a secure and reliable connection between two pipes of matching diameter. Crafted from galvanized malleable iron, this coupling is designed to withstand demanding environments while offering long-lasting durability. The zinc coating provides a robust layer of rust protection, making it ideal for both residential and commercial plumbing applications.

This coupling is a versatile solution for transporting potable water, compressed air, and drainage. It’s also suitable for a wide range of DIY projects.
