Beck C. H. Pipe Nipple, Steel, 3/4", NPTxNPT, 12
A 12-inch steel pipe nipple with NPT threads on both ends, rated for 300 psi at 150 °F and 150 psi steam at 360 °F
- ColorTransparent
- Steel construction rated for 300 psi air and gas lines
- Black anodized finish resists corrosion on 3/4 in NPT threads
- 12 in welded length connects fittings without extra couplings
- Made in USA Grade B steel meets 150 psi steam service
- 13/16 in bore maintains full flow for oil and non-potable water
Steel Pipe Nipple for Fluid Lines
This 3/4 inch nominal steel nipple connects air, gas, non-potable water and oil lines using NPT threads on both ends. It is built to Grade B specifications with a black anodized finish and welded construction. The fitting suits installers who need a 12 inch length for standard plumbing runs.
Pressure and Temperature Boundaries
The nipple handles up to 300 psi at 150 degrees F for general fluids and 150 psi at 360 degrees F for steam service. These ratings define the safe operating envelope for the Grade B steel body. Systems exceeding either pressure or temperature limit require a different fitting class.
Capacity and Flow Headroom
The 13/16 inch inside diameter provides consistent flow area across the full 12 inch length for the media listed. It accommodates typical residential and light commercial demand without restriction. Very high volume or long run installations may need larger nominal sizing to reduce friction loss.

Questions about this item
Should I choose the 12-inch length or a shorter nipple for my 3/4-inch NPT piping run?
The 12-inch length suits runs needing that exact centre-to-centre distance; cut a shorter nipple only if your layout demands less reach.
What does the 300 psi rating mean when the pipe carries 150 °F oil in service?
At 150 °F the Grade B steel nipple holds 300 psi non-shock pressure, matching the stated maximum operating condition.
How does the NPT thread standard limit the pressure I can apply at 360 °F steam temperature?
The tapered NPT threads seal to 150 psi saturated steam at 360 °F, the listed steam-service ceiling for this fitting.
