Flat face hyd. coupling "pressure release" tool

[RedNeckRacin]

Usually a quick rap of the fitting against the loader arm or a flat metal surface is all that is needed to release the pressure, just be handy with a shop towel to clean up the puke.

You must have different fittings than me.
Mine have a nipple that is recessed about an inch into the fitting.

I pull the collar, put it on the mate, and push with all my might. Eventually I resort to the 7/8" wrench and a friggin hammer. Replace pushing with hammering on the wrench. I get some oil in the connector with each hit. Eventually it must be enough that the fitting goes on. Only half of the fittings are a problem, so that makes sense.

When I put on the snow blower/frame, I have no issues.

Well the QD on the implements usually have a protruding nipple. The flat face couples the male end a corner can usually be had to get the pressure released. The female side is a bit trickier. My problem is usually ice build up from the couplers being outside. I have gotten in the habit of hooking my flat face couplers together when I am done using them to keep them clean, maybe that would work for you?

I have 4 female connectors on the loader, and 4 male connectors on a bracket on the tractor. So, nope.

This is on the tractor......


Can't find a pic of the mate.

I'd love to know size/style/mfg part numbers if anyone knew them, too.

I did what I mentioned in my post (post #9 I think) I made a pressure release with extra connectors. The problem isn't with the tractor it's with the implement. If you try to reconnect when the temperature is hotter than when you disconnected.... It builds pressure in the lines. It's a problem with the 'new' Flush Face connectors (ISO16028). They are environmentally friendly, just not User friendly.

I like that.... I bet you're right, I bet it's temperature more than the loader settling. That makes perfect sense.

What kind of connectors do I have on my L3940? I can't seem to figure it out.

On the up side, i only need to buy the "cheap" half of the connector....

Most likely they are 3/8" ISO 7241 "B" type, that's what other L-series owners have purchased from us for the gauge setups we sell.

oooo, awesome. Do the 3/8" use a 7/8" wrench? I *think* that's the size I had to use......
I didn't even know you guys did more than hooks.
I also like how Amazon is 2x your price (and yours is comparable to others, so amazon is stupid).

So maybe $35 solves my problem. Giddyup.
You'll be getting an order, small as it might be..

I wonder if there is reason to buy extra fittings. Maybe a spare set.....

Well, I ordered 'em.
I'll get Ts and nipples and a valve locally.

Then next year at this time, I'll know if it worked. :thumbsup:

Thanks for the order! I'll check on a proper Tee for you to eliminate the nipples.
