Sentry Saf-T-Vise Insertion Tools - The Safest Choice Under Pressure

Sentry Saf-T-Vise insertion tools are used to place and retrieve corrosion coupon holders, injection & sample quills, or chemical injection nozzles & atomizers into high-pressure applications without interruption of the system. With their sturdy but light construction—competitor tools can weigh five times more—these tools are operated easily by only one person and are designed to make insertion and retraction under pressure safe, easy and quick.


A Saf-T-Vise insertion tool is used to place a multi-purpose tool holder into a pressurized system. The insertion tool is used only during insertion or retraction and can be removed once that operation has been completed. This allows just one insertion & retraction tool to be used to service multiple installations, saving money. The operator is able to work from a stable and secure position to the side of the tool, which can be operated from any position.
