Description
xHeat-Sealed simplicity for coil leaks
When a refrigeration coil shows a pinhole or hairline crack, time matters. La-Co’s 11575 Heat-Seal Stik Premixed Epoxy Sealer Stick offers a heat-activated, easy-to-use solution that can help you control leaks while planning longer-term service. With no mixing or measuring required, this stick is ready to work as soon as it’s heated and pressed into place, delivering a smooth, resin-like seal as it cures.
Key benefits at a glance
- Works on R-410A type systems, a common refrigerant blend.
- One-part epoxy, no mixing or measuring needed, simplifying the repair workflow.
- Stick melts, seals and cures in one operation, minimizing downtime.
- Sealing temperature up to 350°F (177°C), enabling on-site action before full component replacement.
Real-world use cases
Imagine a small restaurant’s refrigerated display case or a home kitchen refrigerator that shows a slow refrigerant leak. The Heat-Seal Stik provides a practical option to address the leak location quickly, allowing the cooling system to regain stability while you plan a longer-term service. The tactile experience—warming the stick until it softens, then pressing it into the hole—offers a straightforward, low-muss approach that technicians can integrate into on-site workflows.
The product is suitable for various applications, including compact commercial coolers, under-counter units, and residential appliances that exhibit minor leaks. While it may provide an immediate fix, it is not a substitute for full repair or eventual replacement where required by the system’s condition. Use as part of a broader maintenance plan to keep cooling performance steady.
How to use
- Ensure the leak area is clean and dry for best adhesion.
- Hold the stick near the leak until it begins to melt, then apply by pressing into the opening.
- Continue applying until the seal forms and allow it to cure as directed.
Note: Heat-Seal Stik provides an immediate fix and may be complemented by additional service or replacement to ensure long-term reliability.
