Î
Connect the WEH
®
Connector to a suitable securing device (mechanical connection
via cylinder, rigid fixture, or other means) at the mounting bores “G” on the back of
the connector (or other secure fixture) so that the connector is securely connected
to the test piece when pressurized and can not come loose.
For the tightening torque, please refer to the table below.
Caution: The safety device must be designed to withstand the loosening force that
occurs (plus an appropriate safety tolerance).
Example of the loosening force: The test piece has an inner diameter of
1/2” (= 12.7 mm) and is tested at a maximum of 5 bar.
Loosening force* = pressure x area  0.5 N/mm
2
x 12.7

x n : 4 = 63.33 N (without
consideration of friction forces)
