Why Get our R134a Visual Inspection Sight Glass?
✅ Efficient System Diagnosis: Quickly and clearly determine if refrigerant is contaminated using a sight glass and included condition chart. Spot excess dye, oil, or debris instantly before deciding to flush the system. This gives you confidence in your A/C maintenance decisions and helps prevent unnecessary work.
✅ Leak-Free & Reusable Operation: The integrated ball valve lets you safely deposit refrigerant back into the system after inspection. This means cleaner handling, no wasted refrigerant, and safe control at every step. The design ensures your process remains mess-free and environmentally responsible.
