1/2" Black Forged Steel Half Coupling

The Anvil 1/2" black forged steel half coupling is a Class 3000 pipe fitting designed for high-pressure plumbing systems. It meets ASME B16.11 and ASTM A106 standards for reliable performance in demanding industrial and commercial applications.

FNPT Connection Type and Class 3000 Rating

This half coupling features an FNPT connection type suitable for 1/2 inch pipe size. It is rated for a maximum pressure of 2000 psi at 150 degrees F and a saturated steam pressure of 300 psi at 550 degrees F, with an operating temperature range of -20 to 550 degrees F.

Installers needing a threaded forged steel branch

Suited for installers requiring a durable forged steel half coupling with FNPT threads for branching off a main pipeline. Not intended for users who need a full coupling to join two pipe lengths or a fitting with a different pressure class or connection standard.

Questions about this item

What does the 2000 psi rating mean when the coupling is installed in a working system?

The coupling is rated to hold 2000 psi at 150 °F and 300 psi saturated steam at 550 °F, so it will handle those pressures within the stated temperature range.

How does the FNPT thread standard limit what can be connected to this half coupling?

The FNPT threads follow ASME B1.20.1, so only matching male NPT pipe or fittings will seal properly; other thread forms will not engage correctly.

What clearance and mounting space does the 1 1/8 in outside diameter require?

The coupling measures 1 1/8 in across the outside, so any hole, bracket or adjacent pipe must allow at least that diameter for fit and wrench access.
