Right connectors For Pressure Regulators, Water Traps & Shut Off Valves?

[Pollys13]

I've got the various parts to make my own foot switch operated sandblasting system. Pinch valve from Air Pinch USA, two pressure regulators from China, water trap, foot pedal, shut off valves
See screenshot 9, I've bolted a plywood sheet to the wall. I'm finding it very confusing, npt etc, and what fittings I use to connect the various component parts to each other.
I've contacted the guy in the States he got the various connectors from his local Home Depot. Said the pressure regulators and water trap I was buying would work fine.
In screenshot 9 I recognize a galvanized T connector, the brass looking pipe work, I couldn't find anything like that on Wickes site. In screenshot 9 he has two systems set up,
the red and the white one labeled with tape. as he is using two cabinets as in screenshot 6.
I attach a couple of schematics showing the set up for a single sandblaster, I also enclose another schematic from another site.
Some details of parts on parts :

1 = Compressor Relief Regulating Regulator Valve AR2000 Pressure Gauge Air
Control Adapter Diameter: PT 1/4 Ebay item number = 351047069388
2 = Two Position Three Way PT 1/4" Direct Acting Foot Operated Valve
Air Switch ebay item number = 290913204464
3 = JET JFR-12 1/2-Inch NPT Air Filter/Regulator Size 1/2-Inch search Amazon USA and item will appear.
4 = Pinch valve from Air Pinch USA invoice says has 3/4 inch ports description AT-06-NF-B60-0606-N
part number AP-6798

Any help on this would be very much appreciated,
Cheers.

I just used standard plumbing fittings to put my air system together with lots of ptfe tape, some of the joints leak a tiny bit but at a level that is unimportant in the big scheme of things.

Here is a bit of my set up.

Umm, OK thanks. See if any other replies come in. Meanwhile might take a little run over to Wickes and see if have any connectors/adaptors for fitting into the inlets of the pressure regulator and water trap. Wickes can be quite basic, carry bog standard stock, what I'm after might be too esoteric for them. Will look into plumbing supply place, or ask on a plumbing forum.
Cheers.

You will be better off going to a plumbers merchant, they will be more likely to have a good stock of male/female size adaptors.

I've bought adaptors from a place that does hydraulic hoses. They do rely on the threads to seal but they seem work ok.

OK I see whose local.

Hi,
Can you give me some more info on these connectors, will look into them, as well as whats available at plumbers merchants?
Cheers.

I'm just saying that some one dealing with hydraulic hose systems are likely to have shelves full of different adapters and ends. Lots of bsp stuff. Had to go there to transfer from the relatively small airline fittings to the relatively large water pipe stuff I used to go the distance. If you have two fittings you can't find a connector for in a plumbers merchants, it's worth looking

OK thanks.

as others have said, a hydraulic supply company will have all the fittings you need. To make life easier lay the components out as they will be assembled so you can see exactly what you will need in the way of fittings and hose to join it all up.

NPT = (American) national pipe taper, very similar to BSPT = British standard pipe taper but a slightly different thread pitch, you will probably be able to wind BSPT into NPT, it's bad practice but often seen!

 

[Pollys13]

OK thanks for that.
