Our continuous feed meat injector refills via tube feed as it delivers injection, via multi hole needle, deep into your meat, such as pork or brisket. Simply place the supplied tube of the injector assembly into a container holding the fluid for injection. The meat injector pumps a pre-determined volume of fluid into the meat every time the trigger is depressed. Inject the meat in a grid pattern and you will see the meat swell as it retains the injection in the main muscles.
