Ok guys let me pick your brains a sec. As some of you know Im new to train horns. I used a compressor from pepbpys for my system and its big enough for the job. Its high volume and rated for 140 psi so it has no problem filling my 5 gal tank to 125 it takes about 7 min to fill from empty. However Im having issues with what I would call the head gasket in the compressor moving on me. 3 times now I have had to take the head off the compressor and reposition the gasket to the correct place. It does have a recess it fits into and the head bolts are not loosening up during use that I can notice. What issues might I cause if any if I were to put a thin layer of blue silicone on one side of this gasket to help hold it in place better ? I don’t see where it would hurt but im not well educated in compressors.
I know this isn’t what you want to hear but for what you spent on the Pepboys unit, a few bucks more would have gotten you a Viair. If you want problem free service, consider returning it and buying a Viair.
Otherwise I would exchange it because you do not want silicone particles finding their way into the cylinder.
A Viair will cost about twice as much as this compressor. This is a great little compressor in every way just that gasket is a issue the last couple of days. I do plan on upgrading in the future but its going to be a after the holiday thing lol.
Is it new enough to exchange it at Pepboys? Or does it have a manufacturer’s warranty?
Maybe try to get/buy a new gasket from the manufacturer. If you try the silicone thing, use a high temp variety.
Do you have a Masterflow compressor? Its a red compressor and comes in a black bag with a yellow, coiled hose?
Yes i do the tsunami modle
There’s something not right with this equation. If a gasket is moving it means that there’s not enough binding pressure to seal the surfaces. Sounds to me like you either need a new gasket or you’ve overheated the poor thing and got a warped head in the compressor which means the surfaces between the head cap and the cylinder aren’t mating correctly.
I certainly wouldn’t put any silicone or other goo into the mix! The sealant will most likely get inside the chamber and foul up the rest of the compressor.
Look into buying a Viair that’s rated for 100% duty cycle. Five gallons is a bit much to fill with a small portable compressor like that.
Hate to say it pit bull buy your setup s living on borrowed time. You really need a Viair.
Heck, at least try to get it warrantied and keep the new one to inflate a tire here and there.
Or replace it under warranty and then Craigslist it … and put the cash toward a compressor that will last.
I wouldn’t say that CCW. Just have a small issue to work out then its all golden. Every problem has a solution. The manufacture has sent out a fix it kit for me. with a few extra parts for the just incase situation and its been working great since. They know what im using the compressor for and are standing behind their product. Also I think a lot of the issue was over charging the system. It turns out my air gauge was bad so what I thought was 120 psi was a lot higher. I replaced the bad gauge and put a pressure switch in the system and hopefully it solves the issue. Now the system is regulated at 105 psi and it sounds great at that pressure. Now to work on upgrading the air lines to 3/8 air line rather than the 1/4 od ice maker line ( witch in my defense is rated for 140 psi and does work ). But as so many of you guys have pointed out the 1/4 line are not really 1/4 inside and is actually affecting the volume of my horns. I have a 45’ length of 3/8" air line I will be replacing the line with once I go get the fittings. I know 1/2" will be louder but its to big to run the routing I need for the pull lanyard. Over all this project, problems and all has been fun and this site has been a lot of help along the way. Thanks guys
Now you’re cooking with gas. 
Ahhh, so a little misuse may have been blowing the head gasket.
Hopefully you’ll get some decent life out of it now.
If not - you know what to do. 
Yup I know exactly what to do…get the founds to replace the compressor and take the old one to the gun range I mean it is bright red how much more can it scream long range target if its no good right ? 
An Air Zenith should fix it
Guys I appreciate the product recommends, I really do. But at this point the issue has been solved since I installed pressure switch on the tank and new air gauge on my dash the system is working fine. No blown lines or gaskets and I can accurately monitor the systems air pressure to make sure the pressure switch in functioning correctly. Just to be on the safe side I have a master switch installed on the dash before the pressure switch so I can manually shut the system down should the pressure switch fail. I seams the issue was a simple matter of over pressurizing the system due to my lack of planning and a faulty air gauge giving me a false reading. This install was my first and it has been a learning experience, but im glad to say I have learned the value of complete preplanning an install lol.
