Chain Clamps - KF25 (NW) PTFE
– Lab Society
These PTFE chain clamps attach KF-25 connections together via a centering ring.
With its flexible structure wrapping, sealing a vacuum connection (that uses a KF-25 connection) has never been easier.
Simply place a centering ring between the two KF-25 flanges, and wrap the PTFE clamp around them.
After the chain clamp has been wrapped around the flanges, they may be tightened down via the threaded cap and bar piece, providing a tight seal.
The clamps themselves are made of chemically-resistant PTFE, and they will have an extended lifespan compared to chain clamps made from other materials.
These clamps are great for connecting glass adapters to KF-25 connections as well, due to the torque limiter on the chain clamp!
