About This Product
So your coil siding nailer isn't firing right or losing power?
Might be the piston head valve giving out.

This is the 174054 replacement part that fits a bunch of popular nailers.

Compatible with the MCN150 Metal Connector Nailer, MCN250 Type 0, N66C and N66C-1 coil-fed pneumatic nailers, the CF15, N75C sheathing nailer, DW66C-1 15-degree coil side nailer, DWMC150, and N75C-1 Type 0.

So if you've got one of those, this is your fix.
It's a direct OEM-style replacement – same part number and everything.
Install it and you should get your tool back to firing like new.

The pack comes with one 174054 piston head valve.

Simple as that.
No need to buy a whole new nailer when a small internal part is all that's worn out.

Just make sure your tool matches one of those models before ordering, and you're good to go.

Way cheaper than a service center visit too.
