Squirter® DTI FAQs
How long does the silicone last?
The silicone in the Squirter® DTI is fully cured. This allows it to stay in the DTI during shipping. When the Squirter® DTI is compressed the silicone is pressed out so the operator can see it. When it is pressed out, it has a powdered texture, but the powder clings to the steel surface anywhere from a few days to a few weeks.
This photo was taken on Jan 15, 2003 on Reliant's Parrish site. As you can see from the marks on the steel it was impacted on the 21st and 22nd of Dec. 2002. The silicone is there, but it has deteriorated in appearance.
So as you can see in the right conditions the silicone will last, but the silicone will easily be removed by a light air blast, or a water wash.
Some air-actuated impact tools exhaust "forward", and therefore blow the silicone away immediately if the squirter® has been located on the wrench end. In this case, an exhaust air deflector can be used, or the DTI put on the other end away from the wrench.
If for any reason the silicone is washed away, or blown away, inspection can be done with the use of a feeler gauge.
If it is necessary to keep ALL the squirted silicone in place for many weeks, spraying with a clear urethane will do the trick.
