What the maker puts in writing

  • 304 stainless steel, 3/8”-24UNF thread, withstands 15 MPa / 2200 psi
  • Reusable 500+ cycles
  • Original: bottom valve for gas storage tank refills or pagoda-head inflation
  • Refill with CO2, green gas or soda gas · for beer kegs, soda makers and coffee siphons
  • “The premise is that you have a high-pressure inflation pump.”

Five hundred refills, and the sentence that qualifies them

At the cheapest disposable price on this shelf — $1.05 — five hundred cartridges cost $525.

This body costs $36.10 and is rated for five hundred cycles.

Then: the premise is that you have a high-pressure inflation pump. Not included, not priced, and without it this is a steel tube.

Twelve grams, not sixteen

Every disposable on this shelf holds 16 g (0.6 oz). Both of this maker’s refillables hold 12.

That is a quarter less gas into the keg each time, which is worth knowing before you compare one fill against one cartridge.

One listing, two products

The five bullets above describe the Original and the New type together. The other JaylyHala item on this shelf, at $38, carries exactly the same five bullets.

The title is the only place that tells you which one is in the box.

What readers ask us

Does the arithmetic work?

On the published numbers, yes: 500 cycles at the cheapest disposable price on this shelf ($1.05) is $525 of cartridges, against $36.10 once. The catch is the pump, which the maker says you must already have and does not price.

Twelve grams instead of sixteen — does that matter?

It is a quarter less gas per fill, so a growler that took one 16 g (0.6 oz) disposable may want more than one of these. Every disposable on this shelf is 16 g (0.6 oz); both JaylyHala refillables are 12 g (0.4 oz).

Which model am I buying?

This is the "Original type": a bottom valve for refilling from a gas tank or a pagoda head. The other JaylyHala listing is the "New type" with a double seal and no bottom valve. Both listings carry the same five bullets describing both, so read the title.

    • Substantial number of buyer reviews, useful evidence for real-world performance
    • Genuinely clear ice — free of the cloudy core standard freezing produces — depends on directional freezing technique, not just the mold shape; the listing's clarity marketing should be read as a description of intent, not a guarantee
