​

Pure-Lock single-use flow control and closure clamps have been specifically designed for use with high purity

flexible tubing and textile reinforced flexible hoses which require increased clamping pressure capability.

​

These highly durable polymer pinch clamps can be used with smaller diameter flexible tubing materials with varying 

wall thicknesses and are quickly and easily installed with a positive and simple swing-away locking mechanism.

Pure-Lock single-use tubing clamps are the most cost effective solution which enables the user to easily control

the flow of their high purity and critical liquid media transfer and sampling requirements.
