Installers needing a Class 150 rated steel connector

Suited for maintenance crews and plant engineers joining standard pipe runs at this nominal diameter. The fitting handles saturated steam pressure up to 150 psi and a maximum pressure of 150 psi at 450 degrees F. Buyers who require a different pipe diameter, a welded connection type, or a higher pressure class must select an alternative product.

Pressure and temperature rating determines fit

The coupling is rated for a maximum pressure of 150 psi at 450 degrees Fahrenheit. This single limit governs whether the part matches the design conditions of the steam or fluid system. Verify the operating envelope against this rating before installation to ensure code compliance and joint integrity.

Questions about this item

Will the Class 150 rating and FNPT threads connect to my existing ASME B16.3 steel piping?

Yes, the coupling meets ASME B16.3 and B16.4 standards with FNPT threads for direct connection to compatible steel pipe.

How can I verify the 150 psi pressure rating is holding after installation?

Pressurise the system up to 150 psi at ambient temperature and inspect all joints for leaks; the UL and FM marks confirm the rating was tested.

Does the orange urethane coating come pre-applied or do I need to buy thread sealant separately?

The orange urethane coating is factory-applied for identification and corrosion resistance; thread sealant or tape must be purchased separately for sealing.
