Value Brand

Value Brand Malleable Iron Coupling 1 1/4 in NPT Class 150

SKU CH-509G-67F3D

Malleable iron coupling joins two 1 1/4 in NPT pipes at Class 150 rating

  • Malleable iron construction provides durable pipe connections
  • Class 150 rating supports standard pressure applications
  • 1 1/4 inch NPT threads ensure compatible fittings
  • Galvanized finish resists corrosion in plumbing systems
  • Proposition 65 warning indicates regulated chemical content

Malleable Iron Coupling 1 1/4 in NPT

The Value Brand coupling joins two 1 1/4 inch NPT female threads in a straight run. It is made from galvanised malleable iron rated to Class 150 pressure service. Plumbers and maintenance crews use it to extend or repair threaded pipe systems. The fitting meets the dimensional requirements for standard NPT connections.

Class 150 pressure rating and galvanised finish

The Class 150 rating provides headroom for typical low-pressure water, air and oil lines found in commercial and residential installations. The galvanised coating resists corrosion on the outside of the fitting. The coupling runs out of headroom when system pressure exceeds the Class 150 limit or when the media attacks the iron substrate.

Replaces worn or leaking threaded couplings

This fitting replaces a damaged 1 1/4 inch malleable iron coupling without changing pipe size or thread type. The jump is worth it when the existing coupling shows cracks, heavy corrosion or thread deformation that cannot be sealed. It is not for systems that require a different pressure class, material or thread standard.

Questions about this item

Will the 1 1/4 in NPT threads match the galvanized pipe I already have in place?

Yes, both ends use 1 1/4 in female NPT threads at 11 1/2 threads per inch, so they screw onto standard male NPT pipe of the same size.

How can I confirm the coupling is seated correctly after installation?

Tighten until the joint feels firm and no threads are visible; then pressure-test the line — no leaks means the Class 150 seal is holding.

Does the box include thread sealant or do I need to buy tape separately?

Only the malleable iron coupling is supplied; you will need to purchase PTFE tape or pipe dope separately for the NPT threads.
