Typical Skid Steer Coupler?

[Discount Hydraulic Hose]

Hydraulic Hose Guy,

1/2 will flow as much as 19 GPM's.

3/4 will flow up to 39 GPM's

Are you talking about the thread size/hose size or face opening size.

Neither. I'm referring to the manufacturer's nominal coupler body size.

Nominal sizes can be confusing, and that's why I included a link to the size chart. As it turns out, none of the measurable dimensions of a 1/2" coupler are actually1/2". This is because the nominal size doesn't refer to any outside dimension on the coupler, it refers to size of hose or tubing that coupler is most often used with.

In summary, the only reliable way to identify the size of your coupler is to mate it with a coupler of known size or to match it up to the size charts I linked to in my earlier post.

Not to disagree, but if the male center part of the tip is pressed in, the hole should be 1/2 in for a 1/2 in QD. It is not hard to distinguish between a 1/2 and a 3/4 in QD. Different manufacturers make the sleeves smaller or larger to suit the purpose of the QD.

The price between the two sizes is a big difference.

My original intent was to try to standardize off the skid steer (appears to be 3/4 flush face), but I found out they are QUITE pricey. A buddy showed up with some FREE 1/2" ISO A couplers so they are what is getting installed.

If I ever happen to borrow or rent a skid steer attachment, I will deal with the fluid loss to change out the couplings.

You could go ahead and pre-make some 1/2 to 3/4 adapters. 1/2 on one end, and 3/4 on the other. Male/female, whatever.

Some of the skid steers have low flow and high flow, and therefore the 3/4 flow ability off the aux pump.

No fluid loss. Just snap in place.
