Vacuum KF Tee Fitting (SUS304)

Hello, this is VALVEPARK.

Today we will give you a clear and concise overview of a must-know component in vacuum piping systems - the Vacuum TEE (Vacuum Tee).

What Is a Vacuum KF Tee?

The Vacuum KF Tee is a T-shaped vacuum fitting based on the KF (Klein Flange) standard. It enables three-way connections (branching or merging) in vacuum piping while maintaining a stable vacuum level and playing a key role in gas flow control and system expansion.

Structure and Basic Features

T-shaped structure (3-way connection)
Based on KF standard (NW16 to NW100)
Fast assembly via clamp method
High airtightness through O-ring sealing structure
Easy disassembly and reassembly for convenient maintenance

Product Features

Wide NW Size Range

Extensive lineup from NW16 to NW100, with standardized connection and machining dimensions - ensuring high compatibility for design and installation.

Precision Machining & High Quality
