Anvil 311068001 Wye Fitting
The Anvil 311068001 is a galvanised malleable iron Wye fitting designed for plumbing and steam systems. It features three 3-inch FNPT threaded connections and meets ASTM A-197 and ASME 16.3 standards for reliable service.
Suits 3-inch threaded piping at 1000 psi WOG
This fitting suits installers joining three 3-inch FNPT pipes in water, oil or gas service up to 1000 psi at 150 °F. It also handles saturated steam at 300 psi. Builders needing a different pipe size, connection type or higher temperature rating should look at other fittings.
Pressure rating decides fit
The 1000 psi WOG and 300 psi saturated steam ratings at 150 °F determine whether this Class 150 Wye matches the system design pressure. Verify the operating pressure and temperature against these limits before specifying the part.

Questions about this item
How do I install the 3" FNPT Wye without cross-threading the galvanised malleable iron threads?
Start each connection by hand to align the FNPT threads, then tighten with a pipe wrench on the fitting body — not the branch — until the joint seats at the Class 150 face.
What upkeep will the galvanised malleable iron Wye need after years of 150 °F water service?
Inspect the zinc coating annually for white rust; if the galvanising is breached, replace the fitting — no field recoating restores the original ASTM A-197 protection.
At what pressure does the 300 psi saturated steam rating become the limiting factor during continuous steam use?
The 300 psi saturated steam ceiling is reached well before the 1000 psi WOG limit, so sustained steam service must stay at or below 300 psi.
