Anvil

Anvil 1-1/2" Black Forged Steel Coupling Class 3000

SKU CH-86XS-RVDN9

Black forged steel pipe coupling rated for 1500 psi at 150°F and 300 psi saturated steam at 550°F

  • Handles 1500 psi at 150 °F for high-pressure reliability
  • Rated 300 psi saturated steam at 550 °F for extreme heat
  • Meets ASME B16.11 and ASTM A106 standards for code compliance
  • FNPT threads seal directly without extra adapters
  • Forged steel body resists impact and corrosion in tough environments

1-1/2" Black Forged Steel Coupling

This Class 3000 coupling joins two 1-1/2 inch FNPT pipe ends in high-pressure steam, water, oil or gas systems. It meets ASME B16.11 and ASTM A106 standards for forged steel fittings. The black finish is suitable for general industrial and commercial piping installations. It is rated for temperatures from -20 to 550 degrees Fahrenheit.

Capacity and headroom

The fitting handles a maximum pressure of 1500 psi at 150 degrees Fahrenheit and 300 psi saturated steam pressure at 550 degrees Fahrenheit. It provides reliable service within the full listed temperature range. Systems requiring pressure ratings above 1500 psi or temperatures beyond 550 degrees Fahrenheit will exceed the design limits of this Class 3000 component.

FNPT connection type

The female National Pipe Taper threads conform to ASME B1.20.1 for a seal that tightens with thread engagement. Installers must use compatible male NPT pipe nipples or fittings. This coupling will not connect to flanged, grooved, compression or socket-weld pipe ends without additional adapters.

Highlights

Questions about this item

Will this Class 3000 forged steel coupling thread onto my existing 1-1/2" NPT pipe without leaks?

Yes — the FNPT threads follow ASME B1.20.1 so they match standard 1-1/2" NPT pipe you already have.

How can I confirm the joint is sound once I’ve assembled it?

Pressurise the line up to 1500 psi at 150 °F (or 300 psi saturated steam at 550 °F) and check for leaks; the coupling meets ASME B16.11 and ASTM A106.

Does the box include sealant or gaskets, or must I buy them separately?

Only the black forged steel coupling is supplied; thread sealant or PTFE tape must be purchased separately.
