Description

Product Overview

The KF16 (NW16) stainless steel weldable flange is an ISO-KF standard vacuum component used to create permanent, leak-tight connections in vacuum chambers, pipelines, and custom-fabricated vacuum systems. The weldable stub enables direct integration into stainless steel assemblies while maintaining full compatibility with standard KF16 / NW16 vacuum clamping hardware.

Manufactured from AISI 304 stainless steel, this flange provides excellent corrosion resistance, mechanical strength, and reliable vacuum performance for laboratory, research, and industrial vacuum applications. The 40 mm weld length ensures secure welding, accurate alignment, and long-term sealing integrity.
