  • 316 stainless steel resists corrosion in harsh environments

Zoro Select BULK-PF-775 Flange

This Zoro Select BULK-PF-775 flange is a raised-face industrial fitting designed for 2 inch nominal pipe size. It connects flanged piping to female NPT threads in high-pressure systems. The body is 316 stainless steel with a plain finish for corrosion resistance. It is rated Class 1500 for demanding service conditions.

Suited for high-pressure 316 stainless piping

This flange suits installers joining 2 inch Schedule XXH pipe where 400 psi at 72 degrees F is required. The 8 1/2 inch outside diameter and 8 bolt holes on a 6 1/2 inch bolt circle match the class standard. It is not for low-pressure water lines or plastic piping systems. Buyers needing a welded neck or slip-on connection should look at a different flange type.

Class 1500 pressure rating decides fit

The Class 1500 rating sets the maximum operating pressure at 400 psi at 72 degrees F for this fitting. Engineers must verify the pressure-temperature rating for their specific design temperature before specifying this part. Using it above the rated class risks joint failure. Confirm the schedule and material match the full system specification.

Questions about this item

Should I choose the Class 1500 or a lower class for my 2 in 316 SS piping?

Class 1500 matches the 400 psi rating at 72 degrees F; select it when your system pressure requires that level.

What does the 400 psi @ 72 Degrees F rating mean once the flange is bolted up?

It is the maximum operating pressure the raised-face 316 SS flange can hold at that temperature under the Class 1500 standard.

How does the threaded FNPT connection limit what I can run through this flange?

The FNPT end accepts 2 in nominal pipe threaded to the same schedule; pressure is still capped at 400 psi by the Class 1500 rating.
