ARTICLE REF – ART048
Sticking bleed valves was an article issued recently which focused on the tool used to check the valves and how to determine if they are sticking.
Comment from one our participants:
WC 393 is the product recommended by PWPS for lubricating the bleed valves and it works very well.
Loosen the air line and squirt 2 to 3 squirts of WC393 once a year and bleed valve sticking magically disappears.
It costs a little over $41 for a 12 oz bottle and is available from AP+M in the USA.
