Where to buy quick connect connectors

Thanks Veloce for the contact.

Placed an order after double checking I was ordering the right sizes (they use different descriptions to Macmaster). Seemed to go through OK but might bounce later as Macmaster did when they realise I am overseas. Their system seems to allow for this but so did Macmaster’s but this time they actually quoted a shipping price of about $10 for 6 connectors which seemed reasonable.

Success at last. Just got this confirmation

Veloce ,thanks again for the contact

It will be interesting to see how long it takes for you to receive your order by snail mail, but I hope it works out.

Glad it worked out.

Might just order some for me. Isn’t an bad idea to have backups, we can’t rely on equipments since they are prone to brake without prior warning.

Stuff shipped from the US to Australia goes by airmail since they stopped the seamail option years ago. Should get it in about 2 weeks or so. Really only wanted them as spares and for DIY projects when time permits. They used to have an economy mail option which involved surface shipping within a country but air between. Was much cheaper especially for heavy items. Now prohibitive to buy such things from the US unless they are purchased from large sellers who seem able to get special shipping deals from the USPO. Funny the reverse seems to have happened from the UK where shipping parcels used to be very expensive but now is cheaper. Not sure what happened there. The cheapest seems to be China where sellers on eBay or Aliexpress often send even very cheap items postfree.

Amazon sells them.

But they do not ship them overseas, at least not to Australia even though Amazon recently opened a branch here.

Sorry for that.

I went in on the Vacu-tech Chrome plated ones. I do think they ship international but may be wrong. Thought they got mentioned in this thread already.

No need to be sorry. Might help someone else. Anyway I able to get some from the previous tip from Lenny.

So I just spent $60 on connectors that are way to big and useless to me. I got 1/4 when I should have got 1/8th, and one of my female connector isn’t shut off. I want to put male quick connects on both ends of my line so that I can quick connect from the pump and the cylinder although it would probably just be cheaper to get a second silicone line for my second pump at this point.

I have a small hand pump that I bring traveling with me and a Mityvac at home but only one vacuum line. Since I broke the O-ring on my male connector I removed the quick connect and have been using the rubber cup adapter (looks like a suction cup with a hose attachment) stuck to the top of the cylinder with suction. I really miss being able to disconnect the pump and walk around for a bit.

I plan on going to quick couplings and just want to know the specs for what I need. I also plan on making some DIY cylinders and I’m wondering if there would be a benefit to using larger connectors for stj? I have 1/4 male and it would be cheaper to just get the matching female shutoffs

The O-ring on the male connector is a standard size you should be able to find at a good hardware store: Male Adapter “O” Ring: 5/16 X 3/16 X 1/16

The connectors arrived today well packed in an oversized box.

I want to make an order soon but I don’t know what to get. I really want elbow connectors but I have no clue how sizing works. I got one of the PLC 12 female connectors from amazon, but I accidentally got MPC connectors that don’t fit and are basically trash.

I want to install a t connector / y splitter so that I could connect an aquarium pump in line with my mityvac when I’m in my STJ to monitor pressure (and give my forearm a break). I also want to create a reservoir for wet pumping so that I’ll have a PLC shutoff on my STJ connected to a mason jar reservoir with 2 hosebarbs and a PLC shutoff mounted in the lid; One for liquid intake, one for the tetra pump, and the PLC for the mityvac. Either that or just have one hosebarb and one PLC, then make an adapter that splits from the PLC off into 2 hosebarbs and connect the pumps that way so that when I don’t feel like using the gauge I’m not forced to. I’ll most likely use vinyl tubing unless I can get a good deal on silicone, but I’ll need enough to run from the stj to the reservoir on the ground, then to the mityvac and tetra. I might strap the tetra to the side of the reservoir to save tubing / space, that way I could probably just hosebarb the tetra to the stj and use a single shutoff to connect my mityvac. I feel like doing this would be marginally cheaper than mounting a vacuum gauge to the lid of the jar but for all I know I could be wrong.

I looked all over goddamn everywhere for these o rings. The closest I could find were 5/16 X 3/16 X 3/16 and I ended up with a bag of garbage. I’m literally at the point where I’ll buy a 10 pack of male adapters for $20 if it means I have 2 working couplings and 8 spares. Not a single good hardware store in my whole city. I even looked at tattoo / piercing shops and they didn’t have the right size either.

If I know I’m going to be pumping out water / liquid, should I get chrome connectors for my stj’s? I plan on getting panel mounted female connectors and mounting them to glass jars with o rings and a bit of silicone for good measure . Do you think o-rings would be fine or should I find a grommet that fits? Gaskets? a tutorial posted somewhere would be a godsend
