Even the best built hot melt applicator needs a little TLC every now and then. One of the toughest guns we carry is the 3M PG II pneumatic glue gun. It is engineered for simple, reliable hot melt dispensing but from time to time the 3M PG II does require the replacement of some wear and tear parts.

When to Repair vs Replace
We take a common sense approach to this question. If the spare parts are 50% or more of the value of a new unit, we would start looking at a replacement unit. This is going to vary some depending on how heavily the gun is being used but offers a good place to start.
