The Surebonder 101 check valve assembly is used to attach all of the Surebonder nozzle types. This part helps the PRO Series glue guns from running or dripping and secures the various nozzles tightly to the gun.
Helpful hint! If your Surebonder glue gun seems to be dripping excessively, you may have a worn out check valve nozzle assembly. This can easily be replaced but be sure to warm up the gun before replacing.
