R-410A Leak Stop & UV Dye Refrigerant — 28.2 oz (1.8 lb) Disposable One-Step Can
This is the can-only refill: 28.2 oz (1.8 lb) of R-410A with polymer-free leak stop and UV dye already blended in, and no gauge or hose in the box. It's built for HVAC technicians who already carry charging equipment and want sealant, dye, and refrigerant in a single 1/4″ SAE self-sealing can. It seals small leaks up to 300 microns while you top off, with no injector needed. Need the gauge and hose too? Choose the R-410A leak stop can with gauge and hose.
Is the Can-Only Leak Stop Right for You?
If your truck already has a gauge and hose with a 1/4″ fitting, this is the most economical way to carry leak stop R-410A. You pay for the refrigerant blend, not another set of tools, and it's the natural refill when the can from a gauge kit runs empty.
It suits the recurring slow-leak call, such as an R-410A system that needs a top-off every season. The leak stop seals pinhole leaks up to 300 microns. When a leak is too large to seal, the UV dye already in the system marks the spot for the repair.
Ideal for: Technicians with their own gauges and hoses who service R-410A air conditioners and heat pumps with small, recurring leaks.
Need more capacity? Step up to the R-410A 25 lb Jug, Factory Sealed for full charges after a repair.
Leak stop performance depends on leak size and location; leaks larger than 300 microns require mechanical repair. Charging amounts vary with system size, line-set length, and ambient conditions.

Frequently Asked Questions
Will my existing charging hose fit this can?
Yes, if it has a 1/4″ SAE fitting. The can uses a 1/4″ SAE self-sealing valve. If you need a hose and gauge, the push-button gauge with 1/4″ SAE fitting and hose is sold separately.
What does "polymer-free" leak stop mean?
The sealant formula contains no polymers. It seals small leaks up to 300 microns and goes in with the refrigerant, with no separate injector.
Can I use this as a refill for the leak stop gauge kit?
Yes. This is the same leak stop R-410A can that comes in the gauge and hose kit, so you can reuse your gauge and swap in a fresh can.
What if the leak is too big for the sealant?
Leaks larger than 300 microns need a mechanical repair. The UV dye in the charge helps locate them with a UV light, and a bubble solution like the 32 oz leak detector spray can confirm the exact spot.
Is there a plain R-410A can without leak stop?
Yes. The standard R-410A 28.2 oz can contains refrigerant only, with no sealant or dye.
