Hexagonal stainless steel coupling with threaded female ends

Value Brand

Value Brand 2TY82 3/8 in FNPT 316 Stainless Steel Coupling Class 3000

SKU CH-8BDJ-QAP3F

Connects two 3/8-inch pipes with 316 stainless steel female NPT threads rated for 3000 psi at 100°F

  • 316 stainless steel resists corrosion in harsh environments
  • Female NPT threads with 18 threads per inch ensure secure pipe connections
  • Rated for 3000 psi at 100°F for high-pressure fluid systems
  • Handles 2500 psi steam at 350°F for demanding thermal applications
  • Meets ASTM A-182, ANSI/ASME B1.20.1 and ASME B16.11 standards

3/8" 316 Stainless Coupling

This ZORO SELECT 2TY82 coupling joins two 3/8-inch pipes or tubes in a straight line to create a continuous flow path. Constructed from 316 stainless steel, it provides corrosion resistance and strength for high-pressure fluid systems within specified parameters. The fitting features female National Pipe Thread connections on both ends, each with an 18-thread-per-inch pitch.

Compatibility Check

Verify that your existing piping uses 3/8-inch male NPT threads with an 18-thread-per-inch pitch to match the female ends of this coupling. Confirm the system operating pressure does not exceed 3000 psi at 100°F or 2500 psi steam pressure at 350°F within specified conditions. Ensure the fluid media is compatible with 316 stainless steel construction.

Upgrade Context

This coupling replaces worn, corroded, or lower-rated fittings in systems requiring Class 3000 pressure performance and ASTM A-182 material compliance. The jump is worth it when existing carbon steel or lower-grade stainless fittings show degradation or when thread standards must meet ANSI/ASME B1.20.1 and ASME B16.11 specifications. It is not for systems needing welded connections, larger nominal pipe sizes, or pressure ratings beyond Class 3000 limits.

Questions about this item

Does the 2TY82 coupling come with any thread sealant or gaskets in the box?

The coupling is supplied as the fitting only; thread sealant or tape for the 18-thread-per-inch NPT connections must be purchased separately.

When should I choose the 316 stainless steel Class 3000 version over a lower-pressure alternative?

Select this version when the system requires 3000 psi at 100°F or 2500 psi steam at 350°F and the corrosion resistance of 316 stainless steel.

What does the 3000 psi rating mean once the coupling is installed in a piping system?

It indicates the maximum non-shock working pressure at 100°F per ASME B16.11; at 350°F the steam limit is 2500 psi.
