There's been a lot of progress with aerosol can valve parts lately, and it's making spray control way better. The valves themselves come with finely tuned parts these days. Everything's calibrated—stems, springs, the openings—so the flow and droplet size are spot-on. So you get a consistent spray pattern, from the firs...

Everybody uses aerosol cans—deodorant, hairspray, cooking spray, bug killer, that lubricant stuff in the blue can. The spray comes out pretty even most days, thanks to this tiny aerosol can valve nobody pays attention to. It's just a few bits working together with pressure, nothing high-tech. Push the button (that's th...

Hikers and campers get into long discussions about canister sizes. Every few grams starts to feel noticeable after a couple of days out. The empty steel body for 450g gas canister of fuel ends up being the practical pick for many trips that go longer than a weekend. Here's how it stacks up against the 100g and 230g bod...

Butane Gas Cartridge bodies get marked up in much the same ways time after time. The shell – light steel many often, sometimes thin aluminum – ends up with rounded bulges from steady heat on one spot, dents where stress hits unevenly, sides that bend or twist out of round, or tiny cracks starting along the welded seams...

When you go to grab a Refrigerant Gas Can for topping off a car's AC or doing a small job, you want one that’s not going to fall apart on you. Most of the time, you can tell pretty quickly if it’s okay or if it’s junk just by looking at it really closely and picking it up for a second. A good can doesn’t look like it’...

Camping gas cartridges keep things dead simple—snap one on, light the stove, eat. But everyone who's ever cursed at a hissing connection in the rain or cross-threaded one at 2 a.m. knows the difference between smooth and screwed-up is usually just matching the damn thing right and putting it on without forcing it. Con...

Most folks don’t give a second thought to the tiny valve on the top of those camping gas cans. But that small piece of metal—following something called the EN417 Valve standard—is the reason so many of us can cook dinner on a mountain ridge or heat coffee at a chilly campsite without much fuss. EN417 is basically Europ...

Two-piece aerosol cans keep showing up everywhere in packaging these days. You've got the main body plus the top part crimped on, and that seamless setup really helps the whole thing hold together better under pressure. Lately folks in the industry have been tweaking how they make these things and picking materials tha...

Most of us who get out camping or hiking end up using the usual 450g threaded gas canister for the stove. It’s made of tinplate, weighs somewhere between 175g and 190g empty (varies a little by maker), and hits 625 – 645g when it’s full. Ever put one on the kitchen scales just to see? Do it once – it’s dead easy and st...

Hey, if you've got some Bluefire refrigerant gas canisters on hand, you already know these things are made solid for holding and dispensing refrigerants in AC units or fridge systems. The two-piece design works great with stuff like R-134a, R-410A, hydrocarbon types, fluorinated ones, and all sorts of blends. Bluefire ...

Hey, the valve on your spray can is basically the thing that lets the stuff out when you want it to. It's not complicated: the gas inside pushes everything with pressure. You press the button (that's the actuator), the stem inside drops down, opens up a path, and the product shoots up the dip tube, through a little hol...
