Description
BOLA replacement olive rings Ø 12 mm PTFE are two-part spare sets for laboratory tubing fittings that use a compression olive arrangement. Each set consists of one clamping ring and one olive ring in polytetrafluoroethylene (PTFE), providing chemical resistance and an inert contact surface at the hose interface. The rings are designed for hose outer diameter 12 mm and fit threads M 28 x 2, so damaged or worn olives can be replaced without exchanging the full fitting body. PTFE construction supports aggressive media and high-purity fluid paths typical of analytical and process laboratory setups. These components come from manufacturer Bohlender in the BOLA range and suit regular upkeep of PTFE-compatible connectors. Net weight is 0,004 kg. Packs of 5 pieces offer a practical spare stock for laboratories standardised on 12 mm outer-diameter tubing. Renewing only the clamp and olive pair restores a secure compression seal, reduces downtime, and keeps larger-bore fittings serviceable through repeated assembly cycles in laboratory fluid handling.

Questions about BOLA Spare V-Rings, Two-Part, Ø 12 mm PTFE
What is this article?
BOLA Spare V-Rings, Two-Part, Ø 12 mm PTFE 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.
