You Searched For: NS Joint Sleeves and Connectors

Inert NS joint sleeves and connectors join laboratory pieces using different methods to allow the transference of even harsh gases and liquids. While sleeves are often used for straight horizontal or vertical joining, L-shaped connectors offer more positioning flexibility. Without needing routine greasing, the lack of residue will leave tests uncontaminated. Both NS joint sleeves and connectors feature sealing rings that provide the most secure fit available.
