Value Brand

Value Brand 1/2 in FNPT 316 Stainless Steel Coupling Class 3000

SKU CH-A3CG-8PN6K

Connects two 1/2-inch pipes with 316 stainless steel FNPT threads rated Class 3000 for 3000 psi at 100°F

  • 316 stainless steel resists corrosion in harsh environments
  • Class 3000 rating handles 3000 psi at 100°F
  • FNPT threads on both ends meet ANSI/ASME B1.20.1
  • ASTM A182 compliance confirms material quality for high-pressure service
  • ASME B16.11 standard ensures dimensional accuracy and performance

1/2 in FNPT 316 Stainless Steel Coupling

The Value Brand 1/2 in FNPT 316 Stainless Steel Coupling connects two pipes or tubes inline for high-pressure fluid or steam systems. It suits maintenance technicians and plant engineers who need a corrosion-resistant joint rated for demanding service conditions. The fitting meets ASME B16.11 dimensional and performance standards for forged fittings.

Class 3000 pressure rating

This coupling carries a Class 3000 rating, allowing a maximum internal pressure of 3000 psi at 100°F and a maximum steam pressure of 2500 psi at 350°F. The 316 stainless steel construction complies with ASTM A182, and both FNPT ends use 14 threads per inch to ANSI/ASME B1.20.1.

Inline FNPT joint for 1/2 inch pipe

The coupling threads directly onto 1/2 inch male NPT pipe ends without welding, freeing installers from hot-work permits and reducing downtime. No thread sealant is included, so the assembler must apply a compatible sealant or tape to ensure a leak-tight connection.

Highlights

Questions about this item

What does the Class 3000 rating mean for this 1/2 in FNPT coupling once it is installed in a piping system?

It indicates the fitting can handle up to 3000 psi at 100°F or 2500 psi steam pressure at 350°F, per ASME B16.11.

The ANSI/ASME B1.20.1 thread standard is referenced — what does that cap in practice for this 14 threads-per-inch connection?

It governs the 1/2 in FNPT thread form and engagement so the joint seals reliably at the rated 3000 psi working pressure.

What does the 316 stainless steel body compliant with ASTM A182 require for proper mounting on a 1/2 in pipe?

The female NPT threads accept a matching 1/2 in male NPT pipe or nipple; apply suitable thread sealant as none is pre-applied.
