Description
BOLA one-sided seals with silicone ring and PTFE cuff are laboratory sealing components for GL 32 threaded connections. Each seal measures 29 mm outer diameter by 18,0 mm inner diameter by 9,0 mm height and is intended for tube outer diameters from 17,0 mm to 19,0 mm. In service the process medium contacts only the PTFE cuff, so the silicone elastomer remains shielded from chemical attack while still providing the elasticity needed for a secure one-sided seal. These seals from manufacturer Bohlender are supplied in packs of 10 pieces; order quantities outside that unit are rounded up in steps of ten. Net weight is 0,004 kg. The combination of a flexible silicone ring and a chemically resistant PTFE contact surface makes the seals suitable for glassware assemblies, tubing joints and general laboratory fluid handling where media compatibility and leak-tight GL 32 connections are required. They support everyday research, quality-control and production setups that rely on reliable, chemically inert sealing at the wetted interface.
This article is part of Lids & seals, in Stoppers, caps & closures.

Questions about BOLA One-Sided Gaskets, GL 32, Ø 29 x 18 mm SILICON O-ring with PTFE washer
What is this article?
BOLA One-Sided Gaskets, GL 32, Ø 29 x 18 mm SILICON O-ring with PTFE washer is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Lids & seals, inside Stoppers, caps & closures, in Labware.
Lids and seals are the covers of dishes, jars and tanks: a snap lid, a sealing film, a gasket. The seal is doing the work. A lid that only rests on the rim does not contain a volatile liquid.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
