2-inch FNPT Galvanized Coupling
This coupling joins two pipes with female National Pipe Thread ends. It is made from galvanized malleable iron and rated for Class 150 service. The fitting suits water, oil and gas lines in residential or light commercial plumbing. It is not for systems that require a welded or flanged joint.
Sustained pressure performance
The fitting handles a maximum working pressure of 300 psi at 150 degrees Fahrenheit water, oil or gas. It also withstands saturated steam pressure up to 150 psi. These limits apply to continuous operation rather than brief test spikes. The part is not rated for pressures above these values.
Standards compliance and safety
The coupling meets ASME B16.3 and B16.4, ASTM A197 and A47, and carries FM, UL, NSF-61 and AB1953 listings. California Proposition 65 warnings apply because the product contains a listed chemical. No special cooling or noise mitigation is required for this passive component.

Questions about this item
How much pressure can this 2-inch Class 150 galvanized coupling handle when the system runs hot all day?
It is rated for 300 psi at 150 degrees F WOG and 150 psi saturated steam pressure, so continuous hot-water or steam service stays within those limits.
What pipe and thread type must I already have to install this ZORO SELECT coupling?
You need 2-inch pipe with female NPT threads on both ends; the coupling is FNPT on both sides and matches ASME B16.3 and B16.4 dimensions.
Will this galvanized malleable-iron fitting meet code when I connect it to older steel pipe in a potable-water system?
Yes, it carries NSF-61 and AB1953 listings plus FM and UL approvals, so it complies with lead-free and safety standards for drinking-water installations.
