Please refer to the product description or manufacturer documentation for included items.
The Nu-Calgon EasySeal Ultimate 4050-21 is a professional-grade refrigerant leak sealant designed to permanently repair minor leaks in air conditioning and refrigeration systems without the need for extensive teardown or component replacement. Utilizing advanced TruSeal™ technology, EasySeal Ultimate reacts with system moisture and copper oxidation products at leak sites to form a durable internal weld that seals small and micro leaks.
This direct-inject formula pumps easily through the suction service port and circulates with system oil, providing a fast and effective service solution for residential and commercial HVAC systems. A built-in fluorescent dye helps technicians locate larger leaks using UV inspection tools during follow-up diagnostics.
Compatible with all common refrigerants and compressor oils, EasySeal Ultimate is ideal for treating systems from light residential units up to larger commercial condensers.
