Description
HV plane flange 40 mm is a fire-polished laboratory plane flange with a nominal diameter of 40 mm for use in glass vacuum apparatus and related laboratory setups. The flange incorporates a tube with an outer diameter of 46 mm and a wall thickness of 2,3 mm together with an integrated sealing bed for gasket seating. Offered as a single piece with a net weight of 0,18 kg, it provides a flat sealing face for connection to matching plane flanges. This component from manufacturer Witeg is finished by fire polishing to give a smooth contact surface. The 40 mm HV plane flange belongs to the plane-flange family of laboratory glassware parts and is used when assembling or adapting glass vacuum lines and manifolds. Its defined geometry and sealing-bed design support straightforward installation with appropriate seals. Originating from Germany, the flange is ready for integration into laboratory glass systems that use the HV plane-flange standard. The fire-polished finish, specified tube dimensions and sealing bed make it a practical choice for routine laboratory glass construction.

What is this article?
HV-flat flange, 40 mm, fire polished, w is the article on this page. Luminix Health distributes Witeg 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.
