Parallel threads

EN
Correct sealing of the process connections with parallel threads
sealing rings or WIKA profile sealings.
The sealing of tapered threads (e.g. NPT threads) is made by providing the thread with additional sealing
material such as, for example, PTFE tape (EN 837-2).
For further information on sealings see WIKA data sheet AC 09.08 or under www.wika.com.
Models P-30 and P-31 are high-quality precision measuring instruments. Installation-related
influences (e.g. position dependence, tightening torque) must be eliminated by correcting
the zero point in the application or via the software "EasyCom". Thus an optimum measuring
accuracy of the overall system is ensured.
