KITCHEN SINK
All-in-one HVAC Additive…Seal + Protect + Enhance
Kitchen Sink brings Seal + Protect + Enhance together in a single, time‑saving tube. Its fast‑acting sealant targets qualifying micro-leaks to reduce refrigerant loss and keep systems on line. The Protect component works to remove moisture and neutralize acid—helping prevent corrosion, sludge, and metering device issues—while the Enhance component improves oil circulation, reduces friction, and calms noisy compressors to support measurable efficiency gains. The result is a cleaner, quieter, more reliable system with less wear and fewer nuisance visits—all from one low‑side injection.
Designed for residential and light commercial service, Kitchen Sink streamlines truck stock and installs quickly with Xpress Inject methods. Compatible with common refrigerants and oils, it is A2L ready; not for ammonia (NH3). Available in 1 to 5 ton and 5 to 15 ton sizes. Use on systems with qualifying micro-leaks; larger leaks require conventional repair. When you need to throw everything at it…but the Kitchen Sink.
Key Features and Benefits:
- Triple-action performance: Seal + Protect + Enhance in one tube.
- Fast-acting, permanent seals: Addresses micro-leaks to reduce refrigerant loss.
- Helps enhance efficiency: Formulated to support smoother, more efficient operation.
- Works to eliminate acid and remove moisture: Reduces corrosion, sludge, sticking, seizing, and burnout risks.
- Reduces compressor noise: Helps quiet noisy systems and improve perceived performance.
- Helps prevent compressor burnout: Lower acid and moisture levels help protect windings and lubricants.
- All-in-one, time-saving service: One tube; no special tools required.
- Wide refrigerant compatibility: Works with all refrigerants used in HVACR except ammonia systems. A2L compatible.
- Models: 1 to 5 ton & 5 to 15 ton for residential and light commercial 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.
