3/4" Malleable Iron Wye

The Anvil 0310066808 is a Class 150 malleable iron pipe fitting designed for drainage systems. It features a 3/4 inch FNPT connection and meets ASME B16.3 standards for pressure piping. This wye fitting directs flow in drainage and vent installations for residential or light commercial plumbing.

Replaces worn or damaged drainage fittings

Use this wye when an existing drainage branch fitting shows corrosion, cracking or thread damage that causes leaks. The malleable iron construction handles saturated steam pressure up to 150 psi at 350 degrees F. The upgrade is worth it when the system operates near the 300 psi rating at 150 degrees F and the old fitting cannot hold that pressure.

Simple threaded installation with sealant

The FNPT threads accept standard pipe nipples or adapters without special tools. Apply pipe thread sealant or tape rated for the temperature range of -20 to 350 degrees F. Over-tightening can crack the malleable iron body, so stop when the joint feels snug and the fitting aligns correctly with the pipe run.

Questions about this item

What thread size does the 3/4" malleable iron wye use for pipe connections?

The wye uses FNPT threads on its 3/4 inch pipe size connections.

How should the Class 150 malleable iron wye be threaded onto pipe to avoid leaks?

Apply pipe thread sealant to the male threads, hand-tighten, then use a wrench for one to two additional turns without over-torquing the malleable iron.

When should the Anvil 0310066808 wye be inspected or replaced in a steam system?

Inspect annually if operating near the 150 psi saturated steam limit at 350 degrees F; replace if corrosion, cracks, or thread deformation appear.
