Hey all I got the hornblasters shockers with a 2 tank, 5 toal gal set up. Ive been having some air leakage problems and was wondering if any of you guys have issues with holding air when not using the horns. All my connections are tight, and I use telphon tape and lock tight. Still having problems… I took the water/air separators out and I fixed alot of my leakage. I was loosing about a psi or two every min. Now, I loose about 30 psi every 3-4 hours. Id like to loose NONE at all? Any tips? Anyone else have this problem?
Just spray every connection on your setup with soapy water and check for bubbles
If no external leaks are found the check valve could be bleeding air back up to the compressor
Cant remember off the top of me head if you can separate them from the hose but if not disconnect it from the compressor and fill with soapy water and again check for bubbles
I viewed lots of posts about losing air over time and nearly all of them said use loctite 545 to cure those leaks which is why i did just that when i finally came to do my install and yeah its spot on still got 145psi stored checked yesterday and the last time i used them was oct 2013 stored 150psi !!!
Hope this helps + post up what you find
+1 for this response. Determine if it’s the check valve, if so, address that. If not, pull the system apart, remove all traces of Teflon tape, and re-seal using Loctite 545. You can get it on Amazon if you can’t find it locally; it’s spendy and worth every red (actually, purple) cent you pay for it.
I run a twin 2.5gal (i.e. 5gal total) 200 PSI system with zero leaks. I always had slow leaks until I re-sealed with Loctite 545. That stuff is amazing.
Yeeeesss Loctite 545 without any teflon tape. But the soapy water treatment will tell you if the fittings are leaking. As mentioned, could be the check valve - but it could also be your solenoid valve to the horns.
@UK-Z28 - That is a seriously tight air system!
Okay chaps, a quick couple of questions for you?
What is the difference between Loctite 545 and Loctite 2700, 270, 243, 2400, 2760 etc etc etcetera etc etc I appreciate there are different strengths, but for instance I can’t see any 545 in the UK, only from the States or South Korea.
Also, when using this stuff, is it possible to undo the connections once sealed?
I know ear2ear sure as hell suprised me as i thought id drained it down over the winter
Stinky i dont know the differences between those you listed
But i had to remove my drain plug to put the house rad bleed valve in
I had to heat it up and work it slowly to remove it
I did go overboard with applying the LT545 or
It could have just been the chemical reaction between the ally tank and the brass fittings ???
Stu, where did you purrrrrrrrrrrchase such a substance from, was it from the United Kingdom? 
Pete i think it was from the uk but an ebay purchase cant remember his name etc or find it on me feedback as it was just over a year ago i will keep looking tho
I think Poss DBO found a loctite545 equivelent i remeber reading in a thread about selants
Just had another look the only place in the uk i found was via amazon but at £36 quid thats a bit steep i paid roughly 20 quid i think
Also just trawled the old threads and found the one i was on about 
Can you get the Permatex brand? Permatex has a lot of Loctite equivalents. Instead of 545 it’s 54540.
Just a thought… check into whether you have a local Pirtek outlet. They are like hydraulic hose shop. I bought a sealant fluid called S69 from them and it’s apparently the equivalent stuff to the 545. Works a treat! Seals every time and is easy to undo. They guy in the shop told me that they use it for hydraulic lines so it can handle big pressures.
Loctite 545 is specifically a thread SEALANT, not a thread locker – so don’t think of it in the same realm as the threadlockers for which Loctite is best known. Loctite 545 maintains its lubricity after it sets, so undoing a connection requires roughly similar force that you used when you made it in the first place. It behaves a lot like Teflon tape in this manner…
When it sets up it forms a purple, almost plastic looking substance … which crumbles away when you disconnect the fittings for which it was used as a sealant.
If you’ve seen fittings with a reddish sealant already on them from the factory … think of Loctite 545 in the same realm as that stuff – but worlds better because it’s a liquid when you apply it … that sets into the same sort of substance after your connection’s been made.
It was late and i was knackered last night when postin the above
Just checked thismorning for new posts an realised the copy/paste link to the thread i found didnt work so here goes
