What has to be done to the ports that are in our products to use Zero-Leak Gold Plugs?

Zero-Leak Gold Plugs are interchangeable with SAE J514 style plugs that are used in SAE J1926 ports. In other words, nothing needs to be done other than take out the old style o-ring only SAE J514 plug and install the Zero-Leak Gold Plug. The same applies to the metric Zero-Leak Gold Plugs with the straight thread metric plugs and ports.

The two seals of the Zero-Leak Gold Plug (metal-to-metal primary and elastomeric back up) are internal to the port and therefore it is not necessary to spot face the port in order to install the ZLG plug.

The SAE J1926 and metric port drawings may be found at EPCO's website under "Plugs & Fittings".
