Torque Tips – Suggestions to aid in the determination of Zero-Leak Gold Plug® torque values for individual Zero-Leak Gold Plug applications.

For SAE Zero-Leak Gold® Plug sizes found in the FPI Test Report:

The torque values for the Zero-Leak Gold Plugs in the Fluid Power Institute were the result of the findings reported at the conclusion of the specific test performed. EPCO provides the torque data as a reference point for establishing application specific torque values for ZLGP. As you know, torque values can vary widely depending on vibration, pressure spikes, cycling, temperature changes, etc. Therefore, EPCO suggests the installation torque values for specific applications be established by using the torque values in the FPI test as a base value. See Torque Values Tables. The installation torque values in the test are approximately 60% of the torque value for like sizes of SAE J514 plugs. Start with the FPI torque values and cycle test the application. Should a failure occur, stop the test, clean all components, increase the torque value by 5% and repeat the test. This procedure can be repeated until an acceptable torque value is established.

For SAE Zero-Leak Gold® Plug sizes not covered in the FPI Test Report:

The torque values for the Zero-Leak Gold Plugs in the Fluid Power Institute were the result of the findings reported at the conclusion of the specific test performed. EPCO provides the torque data as a reference point for establishing application specific torque values for ZLGP. As you know, torque values can vary widely depending on vibration, pressure spikes, cycling, temperature changes, etc. Therefore, EPCO suggests the installation torque values for specific applications be established by using the torque value relationships found in the FPI test as a base value. The installation torque values in the test are approximately 60% of the torque value for like sizes of SAE J514 plugs. Start with 60% of the SAE torque values for J514 plugs and cycle test the application. Should a failure occur, stop the test, clean all components, increase the torque value by 5% and repeat the test. This procedure can be repeated until an acceptable torque value is established.

For Metric Zero-Leak Gold® Plug sizes:

EPCO does not have validated torque values for the metric style ZLGP. The torque values for the SAE style Zero-Leak Gold Plugs in the Fluid Power Institute were the result of the findings reported at the conclusion of the specific test performed. EPCO provides the torque data as a reference point for establishing application specific torque values for ZLGP. As you know, torque values can vary widely depending on vibration, pressure spikes, cycling, temperature changes, etc. Therefore, EPCO suggests the installation torque values for specific applications be established by using the torque values in the FPI test as a base value. The installation torque values in the test are approximately 60% of the torque value for like sizes of SAE J514 plugs. It may be possible to establish a metric torque value by identifying the SAE size plug which is closest to the metric size plug in question. Start with the FPI torque value or 60% of the torque values for that SAE plug and cycle test the application. Click and see Torque Values Tables. Should a failure occur, stop the test, clean all components, increase the torque value by 5% and repeat the test. This procedure can be repeated until an acceptable torque value
is established.
