Sentry Saf-T-Vise Quills

To meet DOT operator qualifications to comply with safety standards, product operators must monitor corrosion to enable real-time decision-making around their pipelines.

Sentry Saf-T-Vise quills monitor corrosion at oil & gas and chemical plants, providing an intuitive user experience and the ability to customize their configuration.

In addition, the Saf-T-Vise quills contain a patented safety feature to increase operator safety: an easy-to-use collet that locks the shaft within the process stream in both low and extremely high-pressure conditions. This feature improves operator safety by shielding them from high-energy events from different pressures during plant operation.

The quills are versatile and can operate in both directions to inject chemicals into or take a sample from within a high-pressure pipeline.

To operate the Sentry injection & sample quill as a sampler, you can install a sampling valve on the fluid inlet. This procedure enables the collection of gas or liquid samples from any desired depth without breaking into and interrupting the product stream flow.


To avoid corrosion and equipment damage and enable accurate monitoring, Saf-T-Vise comes with a materials certification and test summary to confirm the product’s materials. These documents improve material traceability to meet the requirements.

The Sentry Saf-T-Vise quills can mount in any orientation at various extension lengths up to 20 feet to reach locations that are difficult to access.

In addition, the components are tested at safety pressure 1.5x the operating pressure. This validation feature assures compliance with PHMSA regulations and NACE standards, assuring safety while avoiding substantial financial penalties.

Finally, Sentry’s 30 years of experience comes with the Saf-T-Vise brand. This expertise ensures the product you select will work for your needs, and our experts also advise your team on a suitable installation location.
