Right from the start I should mention I know very little about compressors, NPT, BSP, adapters, fittings, bore sizes etc,etc. Took me ages to grasp a few basic points 
I'm teaching myself to sandblast surface etch, carve glass. The max pressure I'll be using for this would be 50 psi.
Um, after assembling pinch valve for on/off switch on base of blast pot see my photos.
Used this guys approach http://www.instructables.com/id/Footswitch-Operated-Sandblasting-System/
The pinchvalve is NPT after fitting adapters to fit BSP the quick release couplers are sticking out a bit. I'm thinking, each time I connect and release an airline over time might, weaken seals. I put quite a generous amount of Loctite 542 thread sealent on all the threads. Though that said, should I to try to increase the rigidity of the assembly using Loctite 222 threadlocker, which I have?
The on/off lever on the bottom of the pot as is, will prevent attachment of airline into the T.
What type of fitment do I need to use instead of the T?
I've mounted my airline bits and bobs on a removable wall board. When I did a test wall assembly, to work out how thick noggins should be, to support pressure valves/gauges.
I thought I had things pretty well accurate. However when getting to the last section I found the noggin should have been thicker as the pipework had to go a bit ski wiff to connect up.
Was reluctant at that stage to stop and rectify as had used quite large dollops of Loctite 542 on all the threads of connectors and didn't want to risk disturbing the seals, would have had to make a thicker size noggin.
I thought I could live with a bit of ski wiff pipework but each time I look at it, really bugs me.
So I'm thinking will dismantle that section and reassemble. As have used lot of 542 thread sealant, will it be hard going to break the seals, if so best way to open up? How to I clean threads up prior to putting new sealant on?
On the wall board the top left horizontal quick release coupler. I have what I think is quite a heavy airline to go in this. I'm thinking the weight of the hose might interfere with the seals and affect the rigidity support of the munsen ring. Is there some kind of support hook or something I could use to provide support to this hose?
Cheers people
