SKU CH-0V1X-FSWR0

A 1/2 inch malleable iron union rated Class 300 for Schedule 80 pipe, handling 2,000 psi at 150 degrees Fahrenheit

  • Malleable iron construction withstands heavy-duty service
  • Class 300 rating handles 2,000 psi at 150 °F
  • Female NPT threads ensure leak-tight pipe joints
  • Schedule 80 compatibility suits high-pressure systems

1/2" Class 300 Malleable Iron Union

This Anvil union connects two 1/2 inch NPT female threads in Schedule 80 piping systems. The malleable iron body is rated for Class 300 service with a maximum operating pressure of 2,000 psi at 150 degrees F. It provides a detachable joint for maintenance or reconfiguration without cutting pipe.

Replaces permanent welded or threaded joints

Install this union when a piping section must be removable for cleaning, inspection or equipment swap-outs. The jump from a fixed joint is worth it whenever downtime for disassembly matters more than the added fitting length. It is not suited for systems exceeding the 2,000 psi rating or temperatures above 150 degrees F.

Yes, the union is specified for Pipe Schedule 80 and has 1/2 inch female NPT threads on both ends.
