2 PLUG COUNTER SUNK BRASS

🔧 What it is

From standard plumbing fittings, a 2-inch brass countersunk plug is:

• Size: 2" nominal pipe size (NPT male plug)
• Material: solid brass
• Head style: countersunk (recessed square or slotted drive)
• Function: seals pipe ends or cleanouts

⚙️ What “countersunk” means

• The top of the plug is recessed instead of raised
• Designed so a square drive, wrench, or cleanout tool can sit inside it
• Helps the plug stay flush with the fitting or recessed into a drain body

🧱 What it does

• Closes off 2" threaded pipe openings
• Used in:
  • Sewer and drain cleanouts
  • Plumbing stacks
  • Test ports for pressure systems
• Can be removed later for maintenance access

🏗️ Typical specs (industry standard)

• Thread type: 2" NPT male threads
• Material: brass (sometimes lead-free variants)
• Pressure rating: ~125–200 PSI depending on manufacturer
• Use temperature: plumbing / DWV / mechanical systems

🧠 Simple explanation

It’s basically a big 2-inch brass “screw-in cap” with a recessed top so you can tighten it with a wrench and keep it flush in a cleanout or pipe fitting.
