Description
BOLA replacement inner parts HT for GL 18 fittings are compact spare components intended for hose with an outer diameter of 1,6 mm (1/16 inch). The assembly consists of a PPS clamping ring, a PTFE sealing wedge and sealing plate, and—for screw connections serving hose outer diameters below 3 mm—an additional FKM O-ring that stays clear of the flow medium. Because only PTFE meets the process fluid, the parts offer very good chemical resistance in sensitive laboratory lines. These HT inner parts restore proper sealing on GL 18 threaded connections used with fine 1,6 mm tubing. Supplied as a single piece with a net weight of 0,007 kg, they enable quick service of BOLA screw fittings in analytical, micro-flow and general lab applications. PPS provides the mechanical clamp while PTFE isolates the medium, preserving chemical compatibility across a wide range of reagents. Produced by Bohlender, the inserts match GL 18 geometry for 1,6 mm hose outer diameter and integrate without redesign of existing manifolds. They are well suited to laboratories that rely on small-bore GL tubing systems and need genuine PPS/PTFE replacement inner parts for reliable, chemically inert joints.

What is this article?
BOLA HT Replacement Inner Parts, GL 18 Ø 1,6 mm inner parts made of PPS and 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.
