Reply With QuoteThat's quite timely, as I have one of those el cheapo compressors, and it started doing the old hissing thing this week.
May just ditch it and get a new one.

Everyone knows those cheap little home compressors, the all in one motor/pump with a small tank, often around $100 or so on sale...
Well, this is a removable tank GMC brand.
Picture tells it all... heard a light hissing, found the source, got suspicious as to 'why'....Could have violently blown off if I'd nipped up the plug whilst pressurised.
Look at how little metal there is around the threads.
You get what you pay for.

Jeez you're lucky you found it when you did

My boss got one of the $99 jobs a while ago and blew up two trying to inflate one 4x4 tyre. After the second stopped working he decided to spend a bit more.

SubscriberI`ve had a supper cheap one for a few years now. Has been not to bad. Has had some use too. There is a rubber diaphragm in the pressure cut of switch that had failed. I made another from a inner tube that worked for a while and has been just recently replaced again. The aluminum pipe from the tank to the pressure switch I replaced with a palstic tube. Other than that nothing has so far been wrong with it. Did as a improvement fit a proper regulator/ water trap after the switch so I could spray paint.

A previous employer who could teach a ducks cloaca a thing or two purchased an el cheapo compressor from bunnings, when we first fired it up there was a VERY obvious hissing noise, which was traced to a pinhole in one of the welds on the tank.....
Compressor was replaced under warranty, next one worked quite happily for a week before I noticed that one of the bolts holding the cylinder head on had managed to back itself all the way out..... no problem, grab the sockets, go to wind it back in..... WTF.... a supposedly high tensile, flange head bolt was of such poor quality that not only was its head well and truly off centre to the shank of the bolt, but when I screwed it down tight, the head broke off!

SubscriberIhave had a SIP ( China made) 2.5CFM now for about 9 years.
This looks the same as every generic Chinese compressor around.
The only problems I have had are the diaphragm as above and recently the stop valve on the outlet hose sheared off, replaced with a Supercheap one for about $10 AFAIR.
This to me is amazing value for AFAIR $199.
And it had done several head mods using die grinders which chew up the air, so hasn't had an easy life for a cheapo.
I will probably get a bigger one when it dies but the damn thing won't die!!!!!

Yep, mine is the same..(or was) - Otherwise good value. But needs a massively bigger tank or two for using a die-grinder. Something like 30 seconds on, a couple of minutes pumping up....
An air-tool is in no danger of overheating.

When I worked in a Compressor shop here in bris I went out to service a fairly large unit with a 200 litre tank,Originally Posted by superquag

Done the service,ran the comp up and noticed a hiss grabbed a shifter and instinctively tightened up the non return valve cap and BANG, 200 litres @120 psi Broke the non return valve housing dumping the air into a Compressor shed not much bigger than the unit itself with me trapped inside also.
Needless to say I had very sore ears and felt very lucky not to have caught any flying metal as it bounced around me.
