KF Vacuum Straight Nipple

https://www.s4r.fr/web/image/product.template/304/image_1920?unique=b3bfd4c

The S4R KF Vacuum Straight Nipple provides a rigid in-line connection between compatible KF vacuum components for laboratory vacuum and controlled-atmosphere systems.

Manufactured from 304 stainless steel, the fitting incorporates matching KF quick-flange interfaces at both ends, allowing two components of the same nominal KF size to be connected through a straight section.

It is particularly suitable for tube furnace vacuum lines, pumps, manifolds and laboratory equipment requiring a simple rigid extension between KF components.
