Value Brand Stainless Steel Union 1" NPT x 1" NPT Class 3000

Stainless Steel Union for 1" NPT Pipework

This ZORO SELECT union joins two 1" NPT female threads using 304 stainless steel rated to Class 3000. It provides a reliable connection point in plumbing systems that require corrosion-resistant materials. The fitting suits new installations and maintenance tasks alike. California Proposition 65 warnings apply to this product.

Threaded Design Simplifies Assembly and Service

The union uses 11 1/2 NPT threads on both ends, allowing pipes to be screwed together without welding or soldering. Its three-piece construction lets you separate the joint for inspection or replacement while the pipe runs stay fixed. This saves time during system modifications or routine checks. No special tools beyond standard pipe wrenches are required.

Ideal for Corrosive Fluid Lines and General Plumbing

Builders handling water, oil or mild chemical lines will value the 304 stainless body for its resistance to rust and chemical attack. The Class 3000 rating supports high-pressure service within the fitting's design limits. Buyers needing larger diameters, different thread standards or lower-pressure plastic alternatives should consider other fitting types.
