Quick connectors ?

[big red 3]

I知 using a set of gates quick connectors and they failed. Is there another brand that is better and more durable?

Parker, Faster, Snap-Tite, Stucci, other I can't think of off hand. Can't go wrong with Parker. I am suffering from some leaking Gates too. They were cheap. Should have been free.

Failed how?

Do you have and USE dust caps for the male and female halves.
Dirt getting into the couplers damages the O rings.

Dirt does not do anything good in the hydraulic system either

Awesome thanks

The quick coupler failed The ball valve stuck close poor workmanship. No to dirt. All couplers are free of any contamination

The only time.i have ever seen one stick closed is when their is still pressure on the line. The act of.coupling them together opens them.

I am with LD1 on this one but a little more detail about how pressure could be keeping the coupler ball locker might help you.

I will use a FEL as an example but it applies to any implement as well.

You remove the FEL from the tractor and then disconnect the hoses. They come apart easily so clearly not broken.

Later you come back and try and reconnect the same coupler and you cannot get it to connect. What has happened?

The fluid in the FEL cylinders and hoses is locked in place by the coupler ball. As the FEL settles in place off the tractor, its movement is restrained by the pressure locked in the double acting cylinders but, as a result of this movement, the pressure on the coupler ball has increased dramatically.

Now you cannot get the ball to move so you can connect the coupler.

Some owners resort to starting to unscrew a hose from the cylinder or coupler. This will work but you need to have a rag wrapped around the joint to avoid getting sprayed with oil.

A very small amount of oil has to be released in order to relieve the pressure. An ounce or two at most. Now you can reconnect the coupler.

Some owners have had success by connecting the FEL hoses to one another after the couplers are disconnected at the tractor end immediately after the disconnection.

Some have had success by shutting down the engine and then working the control lever(s) back and forth while the FEL is still connected. The intent is to allow pressures to stabilize before the disconnect.

My practice, and many will rightly find fault with it, is to get a heavy BRASS punch and a heavy hammer. I place the BRASS punch against the coupler ball and then wrap a rag around the coupler.

A few sharp wacks against the punch momentarily pushes the coupler ball back releasing a small amount of oil but sufficient to now use the coupler.

The BRASS punch is the key as to use a metal punch will destroy the coupler ball. BRASS being softer than the coupler ball wont damage it. A piece of hardwood might work but I have not tried it.
