Detailed Description

Gauge adapters with a female ISO parallel thread to male NPT are small but essential components used to connect measurement instruments, such as pressure gauges or transmitters, to piping systems in industrial and oil and gas applications.

The female ISO thread screws directly onto the instrument, while the male NPT thread connects securely to the pipe or tube, creating a tight and leak-resistant connection.

These adapters are made from high-quality materials such as stainless steel or brass, which makes them durable and resistant to corrosion, even in harsh environments. They are designed to handle high pressures, up to 10,000 PSI, ensuring that instruments provide accurate readings without risk of failure.

They follow international thread standards including ASME B1.20.1, SAE AS71051, ISO 7-1, and ISO 228, which guarantees compatibility with other equipment and ensures reliable performance in critical systems. This makes them a practical and dependable choice for monitoring and controlling fluids.
