The Fragola internal pipe plug is a 1/4 NPT blue plug for sealing unused internal NPT ports. It creates a straightforward threaded closure during assembly or service, useful for blocking off pressure, vacuum, or fluid passages that are not required. The blue finish helps distinguish plug size in fabrication and plumbing setups where multiple thread sizes are present.
