These have been used in our plant for years without any issues or premature failures. Drillspot.com is THE place to get them. Great pricing, fast (and often free) shipping. What more could a procurement professional want?

Ccost effectiveness, longevity and user friendly

It is just fine right now

On the spot. Not a direct replacement, but what I wanted was a quality name. I used it on my 33 gal Husky compressor that came with cheap China made one.

Big industries use it

If it came with gauges

Speedaire 4ZM08 Regulator

A very pleasant surprise doing business with Drillspot. Was looking for a replacement regulator for my 4 gallon Hitachi EC119SA Air Compressor when I found Drillspot's website... While it is NOT a direct factory replacement, it works extremely well, has the same style "locking knob" feature to set the outlet air pressure (set it once and pretty much forget about it) and it was HALF the price Hitachi wanted for the factory replacement. Yes, I did have to oblong the plastic where the factory regulator sits by about a 1/4" or so. Took less than two minutes with a file. The shipping was phenomenal!!! Had it 2 days after I ordered it. Price, fast shipping, exactly what I ordered. Kudos to you Drillspot!! I'll be back and I will be refering business your way.

Good product, great price, fast service
