Coupler Name

Coupler Name

I’ve been searching for the name of this quick disconnect coupler and can’t seem to match it 1:1 with anything. Anyone know the exact designation for this coupler? I’ve found some euro and Japanese couplers that are close but not exact.

Custom Air Supply Skid

This here is a custom air supply skid i made for my job.

It operates a pneumatic cart in the water. It has a left and a right track, while also including a float hose that helps keep the hoses above the water so we do not get them entangled.

Everything metal is Stainless Steel 316

While the filter regulator and mist separator are epoxy coated for the environment and corrosiveness it gets. The back board is HDPE

The left and right tracks are provided 120psi, they are constantly fed to the track while it operates on electronic solenoids and purge excess air.

While the float hose only get 45psi to fill and we close the valve.

The air supply is located on the bottom of the skid connecting to the air valve that is located on the wall inside the vault.

The 2 hoses sitting in its holsters connect to 2- 450ft pneumatic hoses that travel with the cart.

We also have a sump pump installed in the vault with lots of rain and moisture.

Patent is pending on it. Im just so proud of it and wanted to share it.

High temperature Pneumatic Tubes

Please advise high temperature pneumatic hoses (120 C or above) brands. I like to have more brand names to compare with.

Need help troubleshooting - cylinder motion jittery

Hi, this is my first time using pneumatics so I don’t really know what I’m doing wrong. I’m running into some frustrating jitter on a pneumatic assembly setup and could use some hardware advice.

I’m using a 2-1/2” bore air cylinder with a 36” stroke to press a heavy part horizontally into a housing, but I can't get the extension to stay smooth. I’ve got a 4-way directional control valve and flow controls mounted on the exhausts for a meter-out configuration, all running on 120 psi shop air. It starts out fine, but as it nears the end of the stroke, it starts to lunge and jitter, which causes it to clash into the part I’m trying to move. I made sure to pre-load the cylinder before starting the motion. I also checked the cylinder for leaking piston seals, and it’s ok.

I can see the pressure on my regulator gauge dropping when the motion slows down and then spiking right as the cylinder jumps forward, making the whole process unreliable. I’m wondering what I should buy to actually stabilize this. Any suggestions on what hardware would fix this would be a huge help.
