ORIGINAL JIGGLER TOP QUALITY BRAND YOU CAN RELY ON
This self priming siphon hose has anti-static, anti-spark hose with a 3/4" (20mm) diameter copper tip that contains a check valve (glass ball and stainless steel spring).
The secret to the siphon hose is in the check valve, which makes it self-priming.
Just set the copper valve end into your liquid and use a few quick strokes up and down to start the self-priming action.
When the fluid in the hose is past the level of fluid in the tank being siphoned, gravity will take over.
That's it, and in less than 2 minutes you can safely transfer liquid!
