The SPF Depot PMC-GU-814 mix chamber is a genuine replacement component engineered to deliver precise material mixing in the PMC Polymac AP spray foam guns. Proper mixing is critical for foam quality, yield, and adhesion. Using an authentic SPF Depot mix chamber helps maintain correct ratio, consistent spray patterns, and reliable jobsite performance all while highly resistant to scoring. Unlike PMC brand chambers, SPF Depot hard coats their chambers to prevent score marks and rusting.
