Stainless steel reducing coupling with threaded ends

Legend Valve

Legend Valve 404-390 2" x 1" SS304 Reducing Coupling equipment

SKU CH-F0G0-3AE12

304 stainless steel reducing coupling connects 2-inch to 1-inch FNPT threads

  • Reduces pipe diameter from 2" to 1" for flow adaptation
  • 304 stainless steel construction resists corrosion in plumbing systems
  • Female NPT threads on both ends enable direct threaded connections
  • New condition ensures full material integrity and clean threads
  • California Proposition 65 warning indicates chemical safety awareness required

Industrial Reducing Coupling 2" x 1

This Legend Valve 404-390 fitting connects a two-inch female NPT pipe to a one-inch female NPT pipe. It is made from 304 stainless steel for corrosion resistance in industrial plumbing systems. The component is supplied new and intended for permanent installation in piping networks.

Sustained Pressure Performance

The 304 stainless steel construction maintains structural integrity under continuous operating pressure without deformation. Thread engagement on both FNPT ends remains stable during prolonged thermal cycling and vibration. Material composition resists galling and stress corrosion cracking over extended service life.

Thermal and Chemical Resistance

304 stainless steel withstands elevated fluid temperatures encountered in normal industrial use without loss of mechanical strength. The coupling adds negligible flow restriction and introduces no moving parts that generate noise. California Proposition 65 notices indicate the product contains chemicals known to cause cancer and reproductive harm.

Questions about this item

Does the stainless steel coupling generate any heat or noise when fluid runs through it continuously?

The 304 stainless steel reducing coupling is a passive fitting with no moving parts, so it produces no noise or heat during continuous flow.

What pipe threads must my existing piping have for this 2" x 1" coupling to seal properly?

Both ends use FNPT threads, so your 2-inch and 1-inch pipes need matching male NPT threads for a direct seal.

Will this 304 stainless steel fitting resist corrosion if I connect it to older galvanised or brass pipework?

304 stainless steel offers good general corrosion resistance, but galvanic effects can occur when mixed with dissimilar metals in the same water system.
