Description
Product Overview
The KF25 (NW25) stainless steel blank off flange cap is an ISO-KF standard vacuum component used to seal unused KF25 vacuum ports, pipelines, and chamber openings. It is commonly applied during system isolation, maintenance, testing, or when temporarily closing vacuum connections in laboratory and industrial systems.
Manufactured from AISI 304 stainless steel, this blind flange cap offers excellent corrosion resistance, mechanical strength, and long service life. When installed using a standard KF25 centering ring, O-ring, and clamp, it provides a reliable, leak-tight vacuum seal suitable for medium and high vacuum applications.
