Air Blow Gun Inputs

Unread postAuthor: revans » Sun May 04, 2008 4:10 am

This is a kind of basic question, but I honestly don't know so . . .

I've got this blow gun here:
http://www.sulco.co.nz/Product?Action=View&Product_id=21782
Could someone please tell me what size connections the inputs are for each end of the blow gun. They are both female threads. I've never worked with anything pneumatic before and have no idea if its 1/8", 1/4", 3/8", 1/2" etc. though I'm guessing it'll be somwhere at the lower end of that list. BTW I've searched the internets for similar blow guns but couldn't find a site that listed both connection sizes. Thanks

EDIT: Ok someone from yahoo answers reckons the smaller is 1/4" and the larger is 3/8". I reckon that's right but can anyone verify that?

1/8" for the smaller and 1/4" for the larger. You can find these at SuperCheap Auto too.

I can't remember but I think that's 6mm and 8mm in metric.
6mm = 1/8"
8mm = 1/4"
10mm = 3/8"
15mm = 1/2"
20mm = 3/4"
25mm = 1"
32mm = 1 1/14"

etc.

That's the nominal diameter of the fitting, obviously 1/8" is really 3mm. But in gas and plumbing fittings thats equal to 6mm metric.
