KITCHEN SINK WITH UV DYE – is the ultimate all‑in‑one Xpress Inject. It combines a fast‑acting leak sealer, System Protect for moisture removal and acid neutralization, System Enhance to reduce noise and help improve efficiency, and a bright UV dye to quickly pinpoint and verify leaks—so techs can fix, protect, enhance, and verify with a single inject. Simplify truck-stock, reduce counter trips, everything you need in one convenient, easy to use tube.
KITCHEN SINK WITH UV DYE – Built for technicians who want maximum impact in minimum time, KSD packs four service functions into one Xpress Inject tube. The sealing component targets qualifying micro-leaks and forms durable, long‑lasting seals to help cut refrigerant loss and keep systems online. System Protect scavenges moisture and neutralizes acids—helping defend compressors, oils, and internal components from corrosion, sludge, and premature wear. System Enhance smooths operation by reducing noise and helping boost efficiency for cleaner, more reliable performance. A high‑visibility UV dye circulates with the refrigerant and fluoresces under UV light, allowing fast leak pinpointing and repair confirmation. Inject on the low side with the system running to simplify service, reduce callbacks, and consolidate truck stock—all while leaving fewer problems behind. When you need to throw everything at it…but the Kitchen Sink.
Key Features and Benefits:
All‑in‑one cartridge: seal + protect + enhance + UV dye in a single Xpress Inject
Fast‑acting leak sealing: forms durable, long‑lasting micro‑seals at leak sites to help reduce refrigerant loss
System Protect: removes moisture and neutralizes acids to help prevent corrosion, sludge, and compressor damage
System Enhance: reduces system noise and helps improve operating efficiency for smoother performance
Built‑in UV DYE: high‑visibility dye speeds leak detection and post‑repair verification under UV light
Polymer‑free, compressible formula: designed not to clog TXVs, cap tubes, or metering devices
Low‑side injection: quick, easy application with the system running
Time and inventory savings: fewer add‑ons to carry; fewer diagnostic steps and callbacks
Broad application: residential and light commercial A/C and heat pumps; see model sizing for coverage

Directions:
This product must be used in accordance with the following directions and by professionals only.
Always read the product label and Safety Data Sheet (SDS) for complete precautionary and first aid information before use.
XPRESS SEAL is designed for quick and effective leak sealing in HVACR systems. Choose the method below that best suits your equipment and job site conditions.
General Safety & Pre-Installation Checks (Applicable to All Methods)
Before beginning, ensure the system is ready and you have the correct XPRESS SEAL product for the system’s tonnage.
Safety First: Always wear appropriate personal protective equipment (PPE), including safety glasses and protective gloves, when working with refrigerants and sealants.
Identify Ports: Clearly identify the low-side (suction) and high-side (liquid) service ports on the system.
System Running & Mode:
Ensure the HVACR system is powered on and running, with the compressor engaged.
If working on a heat pump, set the system to Cooling Mode for optimal sealant distribution.
System Charge: Verify the system has an adequate refrigerant charge. XPRESS SEAL can be injected into a fully charged or partially low system; if significantly low, you may use refrigerant to push the sealant (see Traditional Method alternative).
Refrigerant Compatibility: Confirm the system is NOT an ammonia (NH3) system, as XPRESS SEAL is not compatible.
XPRESS SEAL Size: Ensure you have selected the appropriate XPRESS SEAL cartridge size for the system’s tonnage (e.g., XPS-Mini, XPS-5T, XPS-60T).
Inspect XPRESS SEAL Tube: Do not bend, cut, or deform the tube. Check to ensure small nitrogen bubble is present and free moving in the tube.
Post-Injection Best Practices (Applicable to All Methods)
After injecting XPRESS SEAL, it’s crucial to allow the product to fully circulate and activate:
Run Time: Run the AC unit for a minimum of one (1) hour immediately after injecting XPRESS SEAL. This ensures thorough circulation of the sealant throughout the system. For larger systems or very cold conditions, allow for even longer run times (e.g., 2-4 hours).
System Monitoring: Monitor the system’s operating pressures and temperatures. XPRESS SEAL is designed not to alter system performance or clog metering devices.
Leak Verification: After the recommended run time, verify leak resolution using standard diagnostic methods.
Documentation: Document the application of XPRESS SEAL in the system’s service log, including date, product size, and method used.
Important Notes for Professionals
Refrigerant Charging Concurrent with Sealant: If the system is low on refrigerant, XPRESS SEAL can be injected concurrently with refrigerant charging. Simply connect the XPRESS Inject to the service port and push the sealant into the system using the refrigerant being added, following the appropriate method.
No Pump Down Required: XPRESS SEAL does not require pumping down the system for injection, regardless of refrigerant type.
Polymer-Free Formulation: XPRESS SEAL is formulated to be “polymer free” while in the tube and circulating through the system, protecting sensitive system components.
