IDT-12-N Hydraulic Crimping Tool
Periodic Pressure Relief Valve Check
Test the crimping tool periodically to ensure that the
pressure relief valve activates at the proper pressure.
Order a crimping tool test kit, Ilsco part number
50328913.
The pressure test slugs are manufactured to a precise
diameter and hardness. Do not re-use the test slugs.
Discard each slug after use.
Testing the Crimping Tool
1. Center a new pressure test slug in the crimping
head.
2. Pump the handles to advance the ram. Continue to
pump until the pressure relief valve activates.
3. To release the hydraulic pressure, pull the release
trigger back while pressing down on the handle.
4. Repeat Steps 1 through 3 on two more test slugs.
5. Test the three slugs as follows against the
GO/NO GO gauge as shown.
• If the GO slot fits over the slug and the NO GO
slot does not, the pressure is within the specified
range.
• If the GO slot does not slide over the slug, the
crimping pressure is too low. Send the crimping
tool to Ilsco.
• If the NO GO slot slides over the slug, the crimp-
ing pressure is too high. Send the crimping tool to
Ilsco.
