No, the O-ring seals in Ailun Push-Fit fttings are pre-lubricated with
certifed lubricant during manufacturing, and hence no additional
lubricant need to be applied. If it is necessary to lubricate the seals in the

use any petroleum based lubricants since they're incompatible with
EPDM rubber.

Yes. As with all types of plumbing fittings, new installations of Push-
Fit fttings should be checked to ensure proper connection and
performance一test with water or air on completion and before covering
the pipe. The system should be installed, pressurized and held under
pressure for a period determined by your local and applicable plumbing
regulations.
