Others Advice on air line fitting thread size, please

[Lowndes]

I bought a Vevor pump several months back and one of the items in the accessories and parts bag was a little brass quick connect fitting. This fitting was very thoughtfully included to help connect any fill probe to the air line and compressor. The trouble is that the threads are much smaller than the other threads on the whip, fill probe, or check valves (1/8 in NPT??).





The threads here are female with the ID of 7.05mm and an OD of approx 8.20mm. The threads do no appear to be tapered. The threads almost fit an M8X1 machine screw thread except that the threads are the wrong pitch. It starts for about 1.5 turns and binds up. I'm assuming these are some kind of metric thread standard being that the compressor was made in China.

Unfortunately my thread gauges are too large to fit inside this fitting.

Any ideas??

I'd probably toss the small brass connector then? ...if it doesn't fit anything in the kit it's useless? The quick connect end looks standard at least. Id go shopping for some AV or hill fittings! This would be probably what you need....also...not a huge fan of brass quick connects.

That’ll be a projectile if it fails

One of my compressors came with the small fitting too. It's for an inflation needle that screws into it like you fill up a basketball with. The inflation needle might be in the sack of parts as well. Totally useless!

Best Fittings in the UK sells a kit for fill probe QD fittings, has 2 male QD, 2 seals for them, test plug, and a new/spare female QD. I think the standard thread on stuff like this is 1/8 BSP. They sell them as a quick coupler starter kit. I have had good results with them, always received quality fittings.

Never toss that .. it's a better save it thing for that just in case thing .. you still got it not now trying to hunt it down like your doing here again ..lol

I'd send vevor support a teared stained email with this and pictures and see if they just send you a bag of goodies fittings .
Can't hurt

THANKS, all!!

I found the fittings on BEST FITTINGS, then found Air Venturi fittings at Pyramid for $10 less (freight difference). New QD on the way!!

Stainless makes much more sense, agreed.

Hateful, I did try to get some info weeks ago from Vevor customer service by email. They had NO CLUE. Sent them a picture of the brass QD. Still NO CLUE.

Brass is ok on fittings (but not great) but for a quick disconnect no thanks! I have a mechanic shop and the brass quick connects I had were crud. Replaced em in less than a year wore very fast and thats just 95psi shop air, then the locking balls fell out, super sketch as Mike mentioned! Not worth it. Last pcp fitting order I got a few extras as well, lube the o-ring and off 2 the races.

 

[Lowndes]

Yes, that's what I ordered. Only $19.37 total!!

We'll find out if that's what I actually needed.

They (Vevor) were very prompt about replying to emails but just did not comprehend what I was asking, even the "technical department" no idea what I was talking about.

Ya, I've seen that too. Just needs some good pictures and diagrams to get over the language barrier I guess ..

At least they get back and not a full snub..

The AV SS fitting arrived today. Fits perfectly. Problem solved. Thanks, guys!!

Is this a great forum or what??

And, please don't tell anyone I couldn't figure this out by myself. Stoopid simple and I qualify.

 

[Hateful McNasty]

Ya amazing the fitting needed ( and not just in your case ) ain't in the box and your spending on another order + shipping.. the PCP racket .lol

 

[Lowndes]

I got sum bad news for you, Hateful: it ain't jus' a PCP racket anymore.

Lol.. ya I guess it's all part of that after COVID reset . It's become a joke .. like smoking or drinking I just drop it cold and don't look back ..lol

Dogowski,

You are EXACTLY correct on that brass QD fitting the basket ball needle. THANK YOU, SIR!!

I believe that thread is the Schrader valve stem thread size, 0.305-32.

It was really nice of Vevor to include the little brass QD for a basketball needle but most of our basketballs, footballs, soccer balls don't really need 300 bar.

I made a joke thread on has anyone used there PCP pump to air up a ball or car tire , ECT / not high pressure PCP items .

But the serious Sam's at the forums ruined that . Lol

I am surprised no knucklehead has not made a vid on trying to air stuff up with one ...

oh it's been done, watched some Russian dude air up a transport truck tire with a pcp compressor to see what would happen. Rim blew out of the tire, through the wall and landed about 40 feet away. Some people

I kinda meant for real not to try to blow things up ... Practical everyday use.

I'm sure you let it go long enough to put 4 grand in a tire it's not going to end well ..

I was after using a hand pump to air up . Like how many pumps to fill a b.ball
