Description
BOLA Tri-Clamp gaskets DN 40 are intended for sealing Tri-Clamp connections in line with DIN 32676. Each gasket comprises a silicone ring fitted with elastic PTFE cuffs on both sides, so the medium contacts only PTFE and the seal benefits from universal chemical resistance. The disc measures 50,5 mm in diameter with an inner opening of 38,0 mm, matching pipe systems with the corresponding internal bore for DN 40 joints. This configuration supports secure, media-compatible sealing on standard clamp fittings used in laboratory and technical process setups. Double-sided elastic PTFE cuffs promote reliable seating under clamp load while isolating the silicone body from aggressive fluids. The product is supplied as a single piece with a net weight of 0,0067 kg. These BOLA gaskets from manufacturer Bohlender combine mechanical resilience with a PTFE-wetted surface for DN 40 Tri-Clamp applications that demand chemical inertness and precise dimensional compatibility.

Questions about BOLA Tri-Clamp Gaskets, DN 40, aØ 50,5 mm, iØ 38 mm Double-sided, elastic PTFE s
What is this article?
BOLA Tri-Clamp Gaskets, DN 40, aØ 50,5 mm, iØ 38 mm Double-sided, elastic PTFE s is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in PVC, PTFE & other tubing, inside Tubing, hoses & fittings, in Labware.
PVC is the flexible everyday tube for water and mild aqueous liquids. PTFE is the stiff, almost inert tube for solvents. Other polymers sit between them. The bore, the wall and the chemical resistance are the specification, and the tube is cut to length.
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.
