Description
BOLA replacement olive rings Ø 4 mm are two-part PTFE sets comprising one clamping ring and one compression olive ring for laboratory fittings. Manufactured from polytetrafluoroethylene, they provide chemically inert sealing and retention surfaces on tubing connections. Dimensions match fitting thread M 14 x 2 for hose outer diameter 4 mm. Net weight is 0,001 kg per set. Offered as a pack of 10 pieces from manufacturer Bohlender in the BOLA programme, these spare rings renew the compression interface on fittings, valves and stopcocks when original olives or clamps need replacement. The two-piece layout separates clamping from the wedge/olive function, supporting controlled tightening on 4 mm outer-diameter hose. PTFE construction keeps material compatibility with other BOLA PTFE fluid-handling parts on the same M 14 x 2 thread. Specify these sets for maintenance of existing 4 mm BOLA hose joints where a full two-part olive and clamp combination is required without altering thread or tubing size.

Questions about BOLA Spare V-Rings, Two-Part, Ø 4 mm PTFE
What is this article?
BOLA Spare V-Rings, Two-Part, Ø 4 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.
