Description
BOLA replacement inner parts for GL 18 fittings are intended for hose outer diameters of 3,2 mm (1/8 inch) and restore secure sealing in laboratory tubing connections. Each set comprises a clamping ring in ETFE-glass fibre together with a sealing wedge and sealing plate made of polytetrafluoroethylene (PTFE). For screw fittings designed for hose outer diameters smaller than 3 mm, an additional FKM O-ring is included that remains without contact to the flow medium. Very good chemical resistance is obtained because the medium contacts only PTFE along the wetted path. These spare components from manufacturer Bohlender support routine maintenance of GL-threaded laboratory connectors where inert fluid-contact surfaces are required. Supplied as a pack of 2 pieces with a net weight of 0,005 kg, the parts are practical for stocking replacements on GL 18 assemblies. They suit chemical, analytical and process laboratory setups that rely on GL hose fittings, providing reliable hose retention while preserving the chemical inertness of the fluid path and matching the stated 3,2 mm outer-diameter geometry for straightforward exchange of worn inner sealing elements.

Questions about BOLA Replacement Inner Parts, GL 18 aØ 3,2 mm PTFE, ETFE
What is this article?
BOLA Replacement Inner Parts, GL 18 aØ 3,2 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.
