Acting as a critical safety monitor for your refrigerant circuit, this professional-grade formula is specifically engineered to find and seal microscopic \"pinhole\" leaks that are impossible to detect with standard electronic sniffers. Designed for systems ranging from 1.5 to 5 tons, it features an integrated UV leak-seeking dye that serves as a visual diagnostic tool. Unlike old-style sealants, the EasySeal Direct Inject uses a proprietary \"Direct Inject\" technology that allows it to travel with the oil and refrigerant without clumping or clogging expansion valves (TXVs), ensuring total system harmony while restoring cooling efficiency.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGenuine Part Number 4050-11:\u003c\/strong\u003e Guaranteed OEM-compatible formula that works with all common refrigerants including R-410A, R-22, and R-134a.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced UV Dye Detection:\u003c\/strong\u003e Features a concentrated leak-seeking dye that glows under UV light, allowing technicians to verify the repair or locate larger mechanical breaches.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEliminate Low Charge and Noise Issues:\u003c\/strong\u003e Permanent seal prevents the frequent \"hissing\" of gas leaks and stops the repeated service calls for refrigerant top-offs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety Monitoring Technology:\u003c\/strong\u003e Continuously circulates within the system, remaining in a liquid state until it contacts oxygen at a leak site, where it forms a permanent, flexible seal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect Inject Application:\u003c\/strong\u003e No pump-down or recovery required; the specialized injector allows for a 5-minute application directly into the low-side service port.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eProduct Details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Nu-Calgon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Nu-Calgon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 4050-11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity:\u003c\/strong\u003e Treats systems from 1.5 Ton to 5 Ton\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e R-410A, R-22, R-134a, R-404A, R-507\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e AC and Heat Pump Systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhysical Form:\u003c\/strong\u003e Liquid (Oil-based carrier)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety Rating:\u003c\/strong\u003e Non-clogging to TXVs and Capillary Tubes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.3 lbs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e🛠️ HVAC Depot Pro Tip\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eTake a Picture First —\u003c\/strong\u003e Before injecting the 4050-11, photograph your manifold gauge readings on the low and high sides.
