NOVENT Refrigerant caps were created by industry professionals after evidence of refrigerant theft by teenagers or others, many times resulting in brain damage and even death after inhaling or “huffing” refrigerant. NOVENT created the original tamper resistant refrigerant locking caps for the service valve on all air conditioning and mini split units. These locking caps help prevent tampering or access by unauthorized personal. NOVENT refrigerant locking caps are patented and precisely machined from high grade brass encompassed within a protective refrigerant aluminum casing.
NOVENT refrigerant caps are corrosion resistant and have an O-Ring Seal to provide a positive back-up for leaking service valves. These caps are secured on to a unit with a special key sold only to certified HVAC technicians and provide a tamper resistant barrier to reduce theft, vandalism, and the accidental mixing of refrigerant. NOVENT was the first to develop these caps and strongly supports all EPA Management Programs.
These will be included as another benefit to all of our new customers who get new air conditioners installed by Schaafsma Heating & Cooling.
