flat face quick release couplings usage on shock reservoirs

Anyone ever try using them?

Problem I have is my hose has to pass through the body to mount the Rez inside.
I would prefer to use a 1" hole and a grommet rather than a 3" hole to pass the rez through then deal with sealing the large hole to the 3/4"hose.

Maybe making this to complex...

So you want to use a quick connect hydraulic type fitting similar to what's used for attachments on a tractor?

Idk how well thats gona work. The shocks are charged to something like 200-600 psi. Any psi on those hydro fittings and you can get them to connect

I would think something like this would work.

Hydraulic Quick Connect Fittings

This ones good for 4410psi and 12.15gpm.

I'd say do it and let us know if it works and how well.

Do the quick connect hydraulic connectors introduce air into the system at all? I've wondered that about the tractor ones.

The type I linked to are spring loaded check valve that closes as you remove the coupling.

If the system is run at static pressure ( less than 14.1psi ) the atmospheric pressure could invade the system as you remove the coupling. However, if you are running the system at higher pressures I would think the pressure of the fluid on the check valve would keep the air intrusion to a minimum.

This is just me brainstorming, Although those fittings are used on almost all Heavy Duty truck hydraulic systems in the military.

YMMV,
Joel

Thanks, from what I've seen their won't be any loss of pressure or air into the shock's, if I get the correct ones.

Need to talk to Accutune and get their thoughts..

If I could find a 3" OD grommet with a 3/4" ID I'd just punch a big hole..been looking but can't find any.

Need the 3" hole or min 2.75" for the 2.5" Rez's. They use 3/4" OD lines.

Open to ideas..

Next week need to have a game plan.

If you are passing a 3/4" hose through a 3" hole do you really need a grommet?

If you are concerned about chaffing, I would but the hose through some cheap garden hose to protect it.

I've seen lots of people run their hoses though the smallish access holes in the mounts without grommets and haven't heard about anyone cutting one.

No unless I can use a coupling I will need to pas a 2.5" Rez through the sheetmetal then use a 3" OD grommet with a 3/4" ID to seal to the hose...

I need to get the Rez inside the body as their is no room to mount outside.

My Bypass shocks have the Rez attached and will fit fine inthe mounts its just the rear Rez's that I have to get inside. I will have to have a 90* fitting to get into the body then another to turn parallel to the body inside then the Rez.

Here ya go. Might want to call and ask just how far you can stretch it to get the reservoir through. I do know it's the same rubber as their axle seals.

Grommet Seal-3/4″ I.D. Hole-3″ Diameter-Part#GS100312 – Seals-It – Industrial Seal Manufacturer CT

You'd be hard pressed to find a QD fitting that will work under pressure.

That would work if it can stretch to 2.5"

I'll ask.

Thanks

You will have to recharge the shocks to install those fittings you are looking at. Why not unscrew the rez, slip the grommet on, install your 90* fittings and then recharge the shocks? It sounds much simpler.

I don't know about how much they will flow, as these are real slow tools, but our Holmatro extrication tools use hot quick connects for the hoses, and they run at 10k psi.

However, have you thought about just going with a piggyback coilover?

Because there's this thing called air that you have to bleed out, and you have to pull the shaft to do this.

I have done it. You need a 100% dry break fitting rated for 2500-5000 psi. Rod hall also did it on his home built h1 shocks. Pressurize the reservoirs after installation.

Some provide enough resistance that shock performance will be affected.
