Reliable analysis of oxygen concentrations is crucial in the electrolysis of water, for example, in order to monitor the LEL in a safety-relevant manner. Oxygen is also measured continuously in biogas plants, flue gas analysis and air separation plants. For this purpose, the gas must be transported safely from the sampling point to the analyser through pipe connections.

Due to its oxidising properties, oxygen places high demands on the cleanliness of parts in contact with the medium. The connecting and joining elements are cleaned in accordance with ASTM-G93 to ensure that they are free of particles, oil and grease.
The fittings are supplied individually shrink-wrapped to maintain cleanliness until installation on site. Only fittings frequently used with our gas conditioning components are listed here: Straight screw-in connections, straight pipe connectors, spare parts.
