As contractors, all too often, we work with Fusion guns that are not working properly. However, ensuring that your fusion gun is properly maintained is vital to getting each job done efficiently.

There are many different types of Spray Foam guns available on the market today. One of the most common models is the Fusion Air Purge Gun by Graco. This one is popular because of its reliability, ease of use, low cost for replacement or repair parts and overall excellent performance. It’s also versatile in the use of spray foam insulation for open cells, closed cells and high performance coatings.

Here are a few tips when it comes to your fusion gun’s care and maintenance:

• It’s important to understand that a typical fusion gun consists of 21 different O-Rings. Keeping them clean and greased is important in maintaining smooth operation of all working parts. Be on the look out for flat spots, cracks or chips on the O-Rings. Replace, if needed, and grease before reassembling the gun. O-Rings may be purchased as a complete rebuild kit or in individual packages of six each.
• Is your fusion gun’s trigger slow? Have you checked the trigger assembly? Pulling your gun apart every few weeks, or at least once a month, is a good idea to ensure a properly working piece of equipment.
• As always, review, understand and follow all instruction manuals and warning labels supplied with your equipment from the manufacturer. Only trained and qualified personnel should perform repairs on the equipment.
