Description
BOLA ground joint GL fitting connectors NS 29/32 with a 14,5 mm through-bore and GL 25 thread are fluoroplastic transition pieces that convert standard ground joints to GL screw threads for secure laboratory tubing connections. Made entirely of polytetrafluoroethylene (PTFE), the adapter enables hard-walled tubing such as PTFE, PFA or FEP to be joined via BOLA laboratory screw fittings while ensuring that the medium contacts only PTFE. The ground-joint body incorporates turned rings and a knurled grip that facilitate loosening of the joint after assembly. These connectors support chemical and analytical apparatus where inert wetted surfaces and reliable sealing are essential. Dimensions comprise a core ground joint NS 29/32, a 14,5 mm bore and a GL 25 thread, supplied as a single piece with a net weight of 0,075 kg from manufacturer Bohlender. The PTFE construction delivers the chemical resistance expected of fluoroplastics and maintains dimensional accuracy at both the ground-joint and threaded interfaces. Ideal for bridging classical glassware with modern screw-coupled tubing lines, the fitting helps build flexible, contamination-conscious setups without metallic or elastomeric contact parts in the flow path.

Questions about BOLA Ground Joint-GL Tube Fittings, NS 29/32, Ø 14,5 mm, GL 25 Made of fluoropla
What is this article?
BOLA Ground Joint-GL Tube Fittings, NS 29/32, Ø 14,5 mm, GL 25 Made of fluoropla 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.
