Description
AD 94/20 is an angled-seat flow-through fitting in stainless steel for DN 20 process lines, featuring one mounting position PG 13,5 and two ¾″ internal thread connections. The metal construction supports robust installation in industrial and laboratory flow circuits where mechanical strength and chemical durability are required. Sensors with PG 13,5 thread can be mounted directly into the single port so that the measuring element remains in the process stream. The angled-seat design promotes stable contact between sensor and medium while the dual ¾″ internal threads simplify integration into threaded stainless-steel pipework. Gross weight is 0,40 kg, making the unit compact enough for skid-mounted systems and bench-scale setups alike. Typical uses include continuous monitoring of aqueous and process media with pH, conductivity or related probes. Supplied as one piece from manufacturer Meinsberg - a Xylem brand, the AD 94/20 is intended for permanent DN 20 installations that need a single PG 13,5 sensor seat and threaded stainless-steel process connections.

Questions about AD 94/20
What is this article?
AD 94/20 is the article on this page. Luminix Health distributes Meinsberg - a Xylem brand for laboratory use. It sits in Hose connectors, adapters & fittings, inside Tubing, hoses & fittings, in Labware.
A hose connector or adapter joins two lines, or steps one bore down to another. The barb diameter has to match the tube, and the thread has to match the stopcock or the bottle. Most leaks are a mismatch here, not a hole in the tube.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
