Description
BOLA screw-in connector with ground joint joins an NPT 1/2'' external thread to an NS 19/26 ground joint socket for use on BOLA reactor lids. It is designed to be screwed into matching lid ports, creating a standardised ground-joint connection for glassware, condensers, adapters or related laboratory equipment. The hexagonal grip surface in standard wrench size SW 22 mm supports secure tightening and release with ordinary laboratory wrenches. From manufacturer Bohlender, this fitting bridges threaded BOLA reactor-lid interfaces and conventional conical ground-joint glassware, which is useful in modular synthesis and process setups. Delivered as one piece with a net weight of 0,0245 kg, it suits laboratories that reconfigure reactor lids between experiments and need a defined NS 19/26 outlet. The NPT 1/2'' screw-in thread and NS 19/26 ground joint sleeve dimensions follow the stated BOLA connection geometry, giving a consistent mechanical link between the reactor lid and attached glass apparatus for routine laboratory reactor work.
This article is part of Hose connectors, adapters & fittings, in Tubing, hoses & fittings.

Questions about BOLA Screw In Connector with Ground Joint, NPT 1/2'' - NS 19/26 Male thread on
What is this article?
BOLA Screw In Connector with Ground Joint, NPT 1/2'' - NS 19/26 Male thread on is the article on this page. Luminix Health distributes Bohlender 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.
