Description
BOLA replacement O-rings for stopcock plugs are NBR sealing rings intended for BOLA-Eco stopcock plugs in laboratory glassware and fluid-handling assemblies. The rings are dimensioned for size NS 10,0 with a 1:10 cone and M 7 thread, ensuring a matched fit on the corresponding stopcock plug geometry. Supplied in a pack of 50 pieces, they support routine maintenance and resealing work where worn or damaged O-rings on Eco-type stopcock plugs need replacement without exchanging the full plug assembly. Net weight is 0,001 kg for the pack, underscoring the small-format consumable nature of these seals. Manufactured by Bohlender under the BOLA line, the parts are aimed at laboratories that standardise on BOLA-Eco stopcock plugs and require compatible NBR O-rings for ongoing service. Correct sizing to NS 10,0 and M 7 helps restore reliable sealing performance at the plug interface in typical laboratory stopcock applications. Use these replacement O-rings when maintaining stopcock integrity, preparing spare-part stocks, or refreshing seals during glassware service intervals where NBR material and the stated NS 10,0 / M 7 geometry are specified.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about BOLA Spare-O-rings for Stopcocks, NS 10,0 M 7
What is this article?
BOLA Spare-O-rings for Stopcocks, NS 10,0 M 7 is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Rubber & silicone stoppers, inside Stoppers, caps & closures, in Labware.
A rubber or silicone stopper is pushed into a mouth. The size number corresponds to a top and bottom diameter. Silicone survives higher temperatures and more autoclave cycles. Natural rubber is attacked by oils and by some solvents.
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.
