Leak Saver R290 Refrigerant 3-Pack - Upright Liquid Charging Can

In this review of the Leak Saver R290 Refrigerant 3-Pack, the bottom line is straightforward: this kit is aimed at trained technicians and advanced DIYers who need small, DOT non-refillable R290 cans that support upright liquid charging and self-sealing tops. The single biggest reason to consider it is the convenience of the new ICOR K28 style self-sealing tops combined with upright charging capability, which simplifies filling systems designed specifically for R290 without needing to invert the can during service.

Key Features

• Upright liquid charging: Allows charging while the can stands upright, reducing the need to invert cans and making liquid transfers easier in tight spaces.
• Self-sealing tops: The ICOR K28 style tops are designed to seal after tap removal, helping limit refrigerant loss when used with the correct adapter.
• Adapter requirement: Requires a 7/16' K-28 self-sealing can tap adapter (not included), so technicians can match fittings to their existing gauges and hoses.
• EPA approved usage: Packaged for use under EPA regulations 40 CFR Part 82.17, indicating intended legal usage by qualified personnel.
• DOT non-refillable cans: Supplied in 8 oz non-refillable cans made in the USA for one-time service use and safe disposal after emptying.

Who It's For

This product is best for refrigeration and air conditioning technicians servicing systems specifically designed for R290 propane refrigerant, including small commercial equipment, domestic refrigerators, freezers, dehumidifiers, window ACs, wine coolers, and similar appliances. People who value the ability to charge from an upright can and want cans with self-sealing tops will find this pack convenient when paired with the correct K-28 adapter.

Not suitable for general consumers attempting to service non-R290 systems, nor for anyone without training in flammable refrigerant handling. Also avoid this product if your system is not designed for R290 or if you do not own the required 7/16' K-28 tap adapter or compatible gauge set.

Pros & Cons

Pros

• Supports upright liquid charging, which simplifies liquid transfer in many service situations.
• Self-sealing ICOR K28 style tops can reduce refrigerant loss when used with the correct adapter.

Cons

• Adapter not included; customers must purchase a 7/16' K-28 can tap adapter separately to use the self-sealing tops as intended.
• Some users report mixed fit and occasional leakage, so careful connection technique and inspection are important.

Specifications

Our Verdict

For qualified technicians and competent DIYers working on systems designed for R290, this 3-pack offers practical value: upright charging and self-sealing tops streamline service and reduce handling steps.
