Air Line Couplers

[Greg Masters]

Just bought myself a small compressor - should have done that years ago.

But now I'm confuddled by differing standards of air line couplers. Can someone explain and describe them (with pictures) please?

 

[Marks adventure]

Greg, just plug it in and use it

 

[Greg Masters]

I have. But I want to add bits and bobs.

I bought another airline and some connectors only to find they didn't fit. I now discover that there are at least 2 standards, maybe more!

Been there, done that

If you don't get a reply this afternoon I'll measure and do some piccies of what I eventually ended up with when I get home from work

The ones on the Sliver ones are sold by Machinemart, so I tend to find easier to get the variations you may need

the style on the Brass one tends to be the style you get from B&Q so not as readily available

As far as I know both thread are the same so they fit any Air tools.

I am sure that someone with more knowledge will come along but as far as I can remember the long type are european type connectors and the short type are known as automotive or snap on type connectors and the short ones seem to be most often used on air power tools.
It fairly easy to swap one for the other as they should all be NPT, however NPT (national pipe thread) is the standard pipe thread in the USA. but BSPT (British Standard Pipe Tapered) or BSPP (British Standard Pipe Parallel) will fit NPT in any case I dont think that you should be mix them in very high pressuers but for the sort of pressue used in a compressor its fine to mix them. I would suggest that you check what you have on the air tools and then go to local market or machine mart and get the right female connector for your compressor to match.

Top picture of shiny one (not brass coloured) i think are pcl 1/4" couplings
loads on ebay

It'll all be 1/8 or 1/4 BSP The brass ones are USA and no good to man nor beast, unless you want to be an awkward get.

That's about all you need to know.

Have a look at the Machine mart pages for air line bits, and mix and match.

PCL are fine, cheap and easily available, you'll not go far wrong.
Most diy/hobby tools are 1/4bsp as Vern mentioned.

I will take issue with you on this one, the US fitments are the ones on all the cheap air tools you get from aldi, which if you only use them occasionally are all you need.
I think its also what came fitted to my SIP tools as well.

Ah yes, but, you have to have a hose to run them from, and if you don't get your hose from Aldi, then you could get in trouble, and if your compressor had a US fitting on the regulator, you could be double fecked. Basically, if you only use your own tools, never go anywhere with them, never lend them to anyone and never borrow anyone elses, you can run whatever fitting you like, and live a long and happy life with fluffy bunny wabbits and tweety birds and no one will ever be any the wiser.

PS NEVER buy any tools from Aldi

Why not, you get what you pay for

Correct, you want usless pig metal shite that won't last five minutes,then buy away.

My other half bought me a pistol drill and some sheet shears. The drill done one hole, and the shear cut about 8 inches before it died. Have you ever tried to get your money back off them?

PCL all the way, they let less air through than the other type, but PCL are far more reliable
