Hitachi 371208 J-394 Reduction Valve Set 16Gant1865Dm Nr1890Dc Nr1890Dr

Great product, works exactly as intended. It was dispatched and received promptly.

If you repair your own tools this is an excellent piece of kit. Easy to use and gets your nailer running like new again

It worked quite well in restoring my nailer from being unable to properly sink nails even in softwood. The only downside I had with this tool is how much you may tighten it down. There is a nibble on the end which opens a valve on the nailer but when I checked it afterwards it had become bent. Otherwise I can highly recommend this tool if you want to be able to restore your nailer by yourself. It’s a bit pricey yes but it’s also not cheap to send it for repair each time it needs some air refill.

This is an essential accessory if you own a Hikoki cordless nail gun. This is needed to re-pressurise your nail gun if the pressure drops. I’ve re-pressurised two of my three nailers and they work like new! Worked a treat. Highly recommend.

I’m very happy so far I used to recharge my framing nailer ,men I’ll tell you what ,that nail gun after recharge ,working like a dog!I’m recommending this adapter, use it with care , it will last longer

This ridiculously overpriced item is poorly designed, but unfortunately necessary to fix my Hitachi 30 degree framing nailer mainly which failed after just a few hours use. After many attempts to recharge my gun, carefully following the step-by-step instructions you will find on YouTube without success, I finally fixed my gun using only the part that screws into the gun and the small hose which I hooked up directly the to air nozzle on my compressor and a pair of forceps to clamp off the hose while I unscrewed the fitting from the gun. This is the kind of thing that will make you develop a deep-seated hatred for the shmuck who designed it in the first place. Good luck to all who buy one...but you need the brass fitting on the end and I don't know where else you could get one. At more than $50 this thing amounts to extortion and theft. Good luck to all who need to fix their Hitachi product. I hope it works better for you than it did for me.

This valve set allows you to refill your nailer gun at home, no need to send it to a service centre. Pays itself the first time you use it. Price was lower than ordering from Hikoki Europe and only took a few days to arrive.

Bought this as my gun wasn’t sinking nails below the surface of the timber and used it to fill up the air in the chamber and it is like new.
