  • Seamless Schedule 80 steel construction rated to 300 psi steam at 550 °F
  • 1 inch NPT threads on both ends fit standard Schedule 80 piping systems
  • Black anodized finish resists corrosion in non-potable water and hydrocarbon service
  • Globally sourced Grade B steel nipple meets 7 inch overall length requirement

Anvil Steel Pipe Nipple 1 in NPTxNPT 7 in Schedule

This 1-inch nominal pipe size nipple is built from seamless Grade B steel with a black anodized finish. It serves plumbers, maintenance crews and industrial installers who need a reliable threaded connector for air, gas, non-potable water, oil or steam lines up to 2000 psi at 150 degrees Fahrenheit.

Schedule 80 wall thickness and threaded NPT ends

The heavy Schedule 80 wall handles higher pressures than standard pipe, while the tapered NPT threads on both ends create a tight seal without extra fittings. Black anodizing adds corrosion resistance, and the seamless construction removes weld seams that can leak under vibration or thermal cycling.

Straightforward threaded installation

Apply pipe-thread sealant or tape to the male threads, then tighten to the recommended torque for 1-inch NPT. The main risk is over-tightening, which can crack the fitting or strip threads, especially when mating with dissimilar metals. Ensure the mating component is also rated for Schedule 80 pressure class.

Questions about this item

Will the Schedule 80 steel nipple need replacement due to corrosion or thread wear?

The seamless Grade B steel body with black anodized finish resists corrosion in air, gas, oil, non-potable water and steam service, so replacement is only needed if threads are damaged during installation or if the system exceeds pressure limits.

What pressure limit will be reached first during continuous steam operation?

The maximum steam pressure rating is 300 psi at 550 degrees F, which is lower than the 2000 psi at 150 degrees F rating for general service, so the steam limit governs sustained high-temperature use.

Does the nipple generate heat or noise when steam runs through it all day?

The nipple itself has no moving parts and produces no noise; it will assume the steam temperature of up to 550 degrees F, so external insulation is required to manage surface heat and prevent burns.
