Review on 🔒 LUMITECO 2 PCS Locking Air Chuck with Hose & Tire Valve, Fine Thread Adapter for Secure Air Inflation by Mar Pacora

Each of my Ryobi battery powered inflators have started to leak air around the hose at the end of the cartridge so I ordered a barbed Shraeder adapter here at Revain so I could this can use chucks for air hoses on two Ryobis. Fitting the barbed fittings into the Ryobi hoses was no problem and these hose holders screwed in with ease. I was impressed with their design: Ryobi cartridges consist of thin plastic levers mounted in a stamped and corrugated sheet metal sleeve, with a plastic spike that attaches the cartridge to the hose, all held in place by a small screw in the thin plate held. Metal is thin at best, with a lot of rattling and play in the cartridge mechanism. These adapters use a metal barb and strong metal lever, and the body is metal with a wall thickness about three times that of a Ryobi part. The stepped pin is inserted through the lever and can only be removed by pressing the lever into the housing with GREAT force. Here the question arises. Ryobi uses a piece of black rubber to seal the cartridge around the tire valve. This part will gall the valve threads and eventually the part (or entire cartridge) will need to be replaced. The "rubber" part of these cartridges is gray and looks more like silicone than rubber. And while it provides a decent seal around the stem, it does seem to leak a small amount of air when attached to the tire stem. This leak is a slight hiss and is probably not a problem with car and truck tires etc. But I use my Ryobis to fill the latex hoses on my TRI bike just before starting and there is a slight hiss coming from the hose high low volume pressure means impermissible pressure drop. The old ryobi cartridge, cheaply made, didn't hiss and came out with a sharp pop. This cartridge is less reliable. I've always managed to avoid buying a $50+ Presta cartridge to inflate tires, but I may have to bite the bullet if I can't get it to work better. I will try to take the cartridge apart and see if the ryobi black rubber seal will work in a new cartridge but the question is why is the gray component in this cartridge leaking air when the really cheap ryobi cartridge isn't leaking. And if it's leaking a little now, what will it be every other day in a few months? Again, this is very well made and sturdy for most purposes, including most bike tires. But for my infrequent use of latex inner tubes and racing tires, it doesn't work as well as a cheap ryobi cartridge - get it! So these are well made cartridges and probably perfect for most uses but not for my use. EDIT: There were two such extensions in the pack and I found the second one didn't leak at all. So I experimented with leaking by taking the cartridge apart and removing the silicone rubber gasket that goes around the valve stem. I saw a slight roughness on the surface, a little protruding rubber. Troubleshooting fixed the issue and both work fine for me.
