Anvil 90° Elbow Class 300 3 in FNPT

This malleable iron elbow redirects flow by 90 degrees in a 3 inch FNPT piping system. It carries AAR, FM and UL listings and meets ASME B 16.3 for pressure integrity. The fitting is rated for 1000 psi at 150 degrees F and 300 psi saturated steam at 550 degrees F. It suits new installations that require a Class 300 threaded change of direction.

Threaded FNPT installation and sealing

The female NPT threads accept a matching male pipe end without welding or flanging. Apply a suitable thread sealant and tighten to the recommended engagement to avoid leaks. Over-tightening can crack the malleable iron body, while under-tightening leaves a spiral leak path. The 90 degree bend may restrict access for a wrench in tight runs, so plan the joint orientation before final assembly.

Sustained pressure and temperature performance

Under continuous service the elbow withstands 1000 psi at 150 degrees F and 300 psi saturated steam at 550 degrees F. The malleable iron construction resists creep within the stated temperature range of -20 to 550 degrees F. Repeated thermal cycling between extremes does not degrade the Class 300 rating, and the ASME B 16.3 compliance confirms long-term dimensional stability under load.

Questions about this item

How can I confirm the Anvil 0310502000 elbow is working as intended after installation?

Verify the joint holds pressure up to 1000 psi at 150 degrees F and operates within the -20 to 550 degrees F range without leaks at the FNPT threads.

What comes in the box with the Anvil 0310502000 and what must be purchased separately?

The box contains the 90 degree malleable iron elbow fitting; pipe sealant, thread tape and matching 3 in FNPT pipe nipples are not included and must be bought separately.

Which version of the Anvil 0310502000 should I choose for a Class 300 steam line?

This single model is rated Class 300 with 300 psi saturated steam pressure at 550 degrees F and meets ASME B 16.3, making it the correct choice for that service.
