Value Brand 1 in x 1/2 in FNPT 316 Stainless Steel Reducing Coupling

SKU CH-8S3Z-WBHTH

Connects 1 in and 1/2 in FNPT stainless steel pipes with corrosion-resistant 316 grade construction

  • Reduces pipe size from 1 in to 1/2 in FNPT for flexible plumbing layouts
  • 316 stainless steel construction resists corrosion in demanding fluid-handling environments
  • Female NPT threads on both ends create secure, leak-resistant connections without welding
  • Durable metal body withstands pressure and vibration in permanent piping installations
  • New condition ensures clean threads and full material integrity for immediate assembly

1 in x 1/2 in FNPT 316 Stainless Reducing Coupling

This Zoro Select reducing coupling connects pipe sections with differing diameters in a piping system. It is manufactured from 316 stainless steel to provide corrosion resistance and durability in demanding environments. The fitting creates a secure, stable joint when used with compatible stainless steel pipe. It carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

Suitable for corrosion-resistant piping assemblies

This fitting suits installers joining 1 inch and 1/2 inch FNPT stainless steel pipes where chemical resistance is required. It is not intended for systems using dissimilar metals that risk galvanic corrosion without proper isolation. Buyers needing a straight coupling for identical pipe sizes should select a different fitting type. The product is restricted from sale in certain jurisdictions.

316 stainless steel material specification

The defining specification is the 316 stainless steel construction, which determines the fitting's corrosion resistance and chemical compatibility. This grade dictates whether the coupling meets the requirements for specific fluid types and environmental conditions. Verify that 316 stainless steel is approved for your application media and operating parameters before installation. The Proposition 65 notice also applies to this component.

Questions about this item

Does the 316 stainless steel coupling generate any heat or noise when water runs through it all day?

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

What pipe threads must I already have on my 1 in and 1/2 in lines for this FNPT reducing coupling to seal properly?

Both pipes need female NPT threads matching the 1 in and 1/2 in sizes so the coupling can thread directly into each one.

Will this 316 stainless coupling corrode faster if I connect it to older carbon-steel pipe sections in the same system?

Direct contact between 316 stainless and carbon steel can create galvanic corrosion; use a dielectric union or compatible transition fitting to prevent it.
