Always wear proper protective eyewear and gloves when performing test procedures.
Testing should be completed as quickly as is safe and reasonable. Never leave probes inserted for extended periods to prevent damage/deformation of valve core.
Always select appropriate gauge range for expected line pressure.
Performing a test
Examine probe for sharp burrs that could damage core material (sand or file as necessary). Apply a small amount of silicone lubricant.
Slowly remove plug cap. (At any sign of escaping gas or liquid, retighten cap and determine if the plug has been damaged. Replace as necessary.)
Insert gauge adapter probe or thermometer and record the readings.
Remove probe and replace cap immediately. Never leave probe in the plug any longer than necessary.
Plug will re-seal upon probe removal. Be aware that re-seal may take longer at temperatures below 45°F.
Test readings should be taken as quickly as possible.
