Inflatable tube (standard)

The NBR (nitrile) air tube is a key sealing element designed for use in low-pressure fluid transfer systems such as those found in mud tanks. Made from oil-resistant nitrile rubber, this tube inflates to create a tight, flexible seal between connecting pipes, even when they are slightly misaligned—accommodating up to 14° of variation. It allows for quick engagement and disengagement of lines without the need for tools, and reconversion after deflation typically takes just seconds. The tube performs reliably within a temperature range of -45℃ to 55℃ and is capable of withstanding internal pressures up to 50 PSI above the system’s line pressure.
