The gasket that seals the connection between the spray valve (trigger) and the wand on Birchmeier backpack sprayers. It's the gasket that wears out fastest, and a worn one means drips at the handle and chemical on your hands. This version is nylon, which is heavier-duty and lasts longer than the rubber gasket that comes on a new backpack. At this price, most techs keep a few in the truck.

How do I know the gasket is worn?
Liquid dripping or seeping where the wand meets the trigger handle is the usual sign. A flattened, cracked or missing gasket can't seal, no matter how tight you make the connection.
Why nylon instead of rubber?
Nylon holds its shape and resists wear better than the rubber gasket that ships with new Birchmeier backpacks, so it seals longer between replacements.
Should I replace anything else?
If the connection still leaks with a new gasket, check the wand threads and the trigger valve for damage. The parts breakdown below shows how everything fits together. Call us at 602-371-1993 if you need help.
