Silver 304 stainless steel 90-degree elbow with female FNPT threads on both 1-inch ends

Zoro Select

Zoro Select 409E111N010 304 Stainless Steel 90 Elbow 1 in Fitting Pipe

SKU CH-5S04-0FZ16

A 1-inch stainless steel 90-degree elbow with female FNPT threads rated Class 150 for 300 psi service in air, gas, water, oil and steam lines

  • 304 stainless steel resists corrosion in water, oil and steam systems
  • 90-degree elbow redirects flow between two 1-inch FNPT-threaded pipes
  • Class 150 rating handles 300 psi operating pressure and 150 psi steam
  • Meets ASTM A351 material standard and ANSI B1.20.1 threading requirements
  • Female FNPT threads on both ends connect without extra adapters

Right-angle flow change for 1-inch systems

This 304 stainless steel 90-degree elbow connects two 1-inch pipes at a right angle to redirect flow in industrial piping installations. Female FNPT threads on both ends accept compatible threaded pipes or fittings for air, natural gas, non-potable water, oil, potable water, and steam applications. The fitting meets ASTM-A-351 material standards and conforms to ANSI B1.20.1 threading specifications.

Threaded ends without sealant included

Both ends feature 1-inch FNPT threads at 11 threads per inch for direct connection to matching male-threaded components. No pre-applied thread sealant or seals are supplied, so installers must provide appropriate sealing material for leak-free joints. The silver-coloured 304 stainless construction resists corrosion across the listed fluid types.

Class 150 pressure ceiling limits steam use

Rated to MSS-SP-114 Class 150, the elbow handles a maximum operating pressure of 300 psi for general service but only 150 psi for steam. Systems exceeding these limits require a higher-class fitting. The 90-degree geometry also introduces flow restriction that designers must account for in pressure-drop calculations.

Questions about this item

Will the 304 stainless steel need replacement due to corrosion in a potable water system?

The 304 stainless steel resists corrosion in potable water, but service life depends on water chemistry and temperature.

Does the 300 psi pressure rating or the 150 psi steam limit restrict continuous high-pressure flow first?

The 150 psi steam rating is the lower limit and will govern before the 300 psi general rating during steam service.

How much heat does the fitting radiate when steam runs through it at 150 psi all day?

The fitting will reach steam temperature, so insulation is recommended to control surface heat and protect nearby components.
