This can foam gun is an economical alternative to more high priced foam guns. It has an all steel chamber, adjustable output flow regulator, comfort grip handle. With proper care and maintenance, using the appropriate can foam gun cleaner (we recommend our N-PF10-GUNCLEAN), this gun will give plenty of good service for the money. At this price though, you could treat it as a disposable foam gun and save yourself more time doing other projects. No rebuild kits are available for this foam gun.
