Stainless steel half coupling with threaded female end

Value Brand

Value Brand 1-1/2" FNPT 316 SS Half Coupling

SKU CH-1DM8-3S9MC

Connects 1-1/2 inch FNPT pipe at 300 psi using 316 stainless steel for corrosion resistance

  • 316 stainless steel resists corrosion in harsh environments
  • FNPT threads create a secure, leak-tight seal
  • Class 150 rating handles up to 300 psi working pressure
  • Meets ANSI B1.20.1 for reliable dimensional accuracy
  • 1-1/2 inch size fits standard plumbing systems

Pipe fitting for 1-1/2" FNPT systems

This Value Brand half coupling is manufactured from 316 stainless steel for corrosion-resistant piping connections. It carries a Class 150 rating and meets ANSI B 1.20.1 thread standards. The component suits fluid or gas lines requiring a female NPT inlet.

Rated for 300 psi pressure and 150 psi steam

Normal operating limits reach 300 psi at ambient temperature and 150 psi for saturated steam service. The 316 alloy construction resists thermal cycling without deformation. No moving parts or seals generate noise or draw power during use.

Replaces carbon steel or lower-grade couplings

The upgrade is justified when media compatibility demands molybdenum-bearing 316 stainless steel. It is not intended for pressures above Class 150 or for pipe sizes other than 1-1/2 inch FNPT.

Questions about this item

How do I install the 1-1/2" FNPT half coupling and what step is often missed?

Wrap male threads with PTFE tape or pipe dope, then thread into the FNPT end. The step often missed is tightening to the ANSI B1.20.1 engagement depth rather than hand-tight only.

What maintenance or replacement will the 316 stainless steel coupling need later?

316 stainless resists corrosion, so routine replacement is not scheduled. Inspect threads and sealing surfaces during system maintenance; replace if galling, cracking or leakage appears.

What pressure limit shows up first under sustained use?

The 150 psi steam rating is lower than the 300 psi general pressure rating, so steam service hits its limit first during sustained operation.
