Copper Adapter for 1-1/4 Inch Tube

The Nibco wrot copper adapter connects 1-1/4 inch tube to a female NPT thread in plumbing and medical gas systems. It is built for installers who need a certified fitting that meets strict health-care and industrial standards.

Check Thread Type and Pressure Rating

Verify that the mating connection uses a female NPT thread and that the system pressure does not exceed 351 psi at 200 degrees F. Confirm the operating temperature stays within the minus 20 to 400 degrees F range before installation.

Wrot Copper Construction with Certified Compliance

The fitting is made from ASTM B75 alloy C12200 wrot copper and carries NSF/ANSI 61 Annex G, ASME B16.22, MSS SP-104 and NFPA 99 certifications. These approvals allow daily use in medical gas, vacuum and compressed gas pipelines without additional qualification.

Questions about this item

Does the adapter come with any gaskets, solder or flux in the package?

The box contains only the wrot-copper FTG x FNPT adapter; gaskets, solder and flux are sold separately.

How do I know this 1-1/4 in fitting meets the medical-gas standard NFPA 99 and CGA G-4.1?

It is third-party certified to NSF/ANSI 61 Annex G, ASME B16.22, MSS SP-104, NFPA 99 and CGA G-4.1 for healthcare gas and vacuum systems.

Will the 351 psi rating at 200 °F hold up in a chilled-water loop that drops to -20 °F?

Yes — the published temperature range is -20 °F to 400 °F, and the 351 psi maximum pressure is specified at 200 °F, so the fitting is rated for the full range.
