Product identity

The Zoro Select 2UA59 is a 304 stainless steel 90-degree elbow with 1-inch female NPT threads on both ends. It carries a Class 3000 pressure rating of 3000 psi at 100°F and a steam rating of 2500 psi at 350°F. The fitting complies with ASTM A182, ANSI/ASME B1.20.1 and ASME B16.11 standards.

Suitable applications

This elbow suits piping systems that require a right-angle connection between two 1-inch NPT pipes at Class 3000 pressure levels. It is not for installations needing a different nominal pipe size, a straight coupling, a tee or a reducing fitting. Buyers who need a lower pressure class or a different thread standard should look elsewhere.

Pre-order checks

Verify that both mating pipes are 1-inch NPT with 11 1/2 threads per inch to match the female ends. Confirm the system design pressure and temperature stay within the 3000 psi at 100°F or 2500 psi steam at 350°F limits. Ensure 304 stainless steel is compatible with the fluid and environment in your application.

Questions about this item

Which pipe size and thread standard must the mating pipes follow to connect to this 1-inch female NPT elbow?

Both pipes must be 1-inch nominal size with 11 1/2 threads per inch female NPT threads per ANSI/ASME B1.20.1 to match the elbow's ends.

Will the Class 3000 rating handle the same steam pressure as the water pressure at 100°F?

No — the elbow is rated 3000 psi at 100°F for water but only 2500 psi at 350°F for steam service.

How can I verify the fitting meets the ASME B16.11 pressure class after installation?

Hydrostatically test the assembled joint to the Class 3000 design pressure of 3000 psi at ambient temperature and confirm no leakage.
