Radium Engineering 1/8in NPT Plug | Universal (14-0172)

Every unused NPT port is a future leak unless it meets a proper plug first.

The Radium Engineering 1/8" NPT Plug seals the small tapered ports scattered across fuel system hardware: regulator gauge ports, rail sensor bosses, and vacuum block spares, all closed with a machined plug on the thread standard they carry.

What You'll Feel

• Gauge and sensor ports properly sealed until their hardware arrives
• A tapered thread seal that holds pressure without drama
• Clean hardware-store-free finishing on Radium regulators and rails

Features

• 1/8" NPT male plug
• Machined construction suitable for fuel, oil, and coolant duty

The Details

NPT seals on the taper, so the install rule differs from ORB: apply PTFE thread sealant paste to the plug threads before installation, thread in snug without over-torquing the receiving boss, and the joint holds. Common homes include the 1/8" NPT gauge ports on Radium regulators awaiting sensors, rail NPT bosses, and any component whose spare NPT port a build has not claimed yet. Sealant not included. Sold individually.
