Description
BOLA replacement inner parts for GL 14 fittings with 4,0 mm hose outer diameter are spare sealing components for laboratory fluid connections. Each set comprises a clamping ring in ETFE plus a sealing wedge and sealing plate made of PTFE. For screw fittings used with hose outer diameters smaller than 3 mm, an additional FKM O-ring is included; that O-ring does not contact the flow medium. The wetted path is limited to PTFE, giving very good chemical resistance for aggressive media in analytical and process work. Dimensions match tubing of 4,0 mm outer diameter and a GL 14 thread, supporting secure, chemically inert joints when original inner parts wear or need renewal. Pack size is 1 pc with a net weight of 0,003 kg. These BOLA components from manufacturer Bohlender suit labs that standardise on PTFE-wetted fluid paths and require consistent spares for GL screw connections in everyday laboratory tubing systems.

Questions about BOLA Replacement Inner Parts, GL 14 aØ 4 mm PTFE, ETFE
What is this article?
BOLA Replacement Inner Parts, GL 14 aØ 4 mm PTFE, ETFE 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.
