A needle pin inflator was used in the chuck of my decades old Interdynamics TruckAir 300 compressor to inflate a ball.The Harbor Freight needle pin inflator base got stuck in the chuck and would not come out without destroying the chuck. Using pliers pulled the needle from the base.The LUMITECO 1/4″ replacement chuck fit perfectly in the compressor’s air hose, and rotating the hose clamp around got it out of the way.Locking it on to the tire’s air valve was smooth, but pulling it off was a little tricky.I attribute that to the rubber inside the chuck being new, whereas the rubber in the old chuck was worn from years of use.The corner of the opening for the lever and the two side pins were sharp, but the use of a file took care of that.The replacement chuck will give my compressor another 20 years of service, as long as I stay away from Harbor Freight needle pin inflators. Sorry, HF.I read the reviews for this compressor on amazon and was surprised by all the negative ones.Mine has given me over twenty years of good service.One commenter said the 12v plug fell apart in his hand.The first thing I did when I got the compressor in 2003 was to replace the admittedly cheap factory plug with a marine-grade 12v plug from Marine West, and have never looked back.
