Air hose quick connects for bypass connection

[97Astro]

I see a potential solution for mounting remote bypass filters on crampted installations. The air hose quick connect fittings may be an excellent way to connect the hoses to the filter body. I was looking at them the other day at Harbor Freight. Since they are "Air Tight" they should also be oil tight. When the female side is disconnected, it becomes leak free.

Benefits: Ability to remove the housing easily for servicing under the hood. My van isn't known for roominess in the engine bay until the fan shroud is removed.

Liabilities: Oil flow volumn through the connectors.

My van has cooler lines for both the engine oil and transmission. I plan to filter both components.

Comments will be appreciated on this.

I dunno. The only way I was able to weed out the oil drips on my car was to do the following:

1. Clean fittings with brake cleaner to remove all oil & dirt

2. Work some rubber silicone into the MALE thread of each fitting.

3. Install fitting & let sit overnight so that the silicone can set.

All other methods I have tried developed slow leaks that would lose a quart or more every 3-4k miles. I've tried: brake line, liquid teflon, teflon tape, black stuff that comes with the Frantz filter kit. What I settled on was rubber hose & rubber silicone for the fittings. Although quick disconnects would be a very nice thing in concept, I think they would leak (like **** ) in practice. Then again, I use Mobil 1 synthetic exclusively & synthetic oil is know for its leaking. I'm thinking that what they mean by "air tight" is that you won't hear them hiss when connected to an air compressor.

If you want true quick disconnnects I would use hydraulic discos. They are probably very expensive. Any of these type of fitting will eventually have a fatigue factor. I'm unsure how, in your intended use, this would play out. I would just visit a hydraulic shop and ask what they would do. You aren't their bread and butter, so you may actually get not too bad of a deal from them.

I had wanted to do this with a cooler. It would have been nice to just bypass it during cold weather by hooking the hoses together ..but it would probably be cheaper to just buy a thermostat or valve it with a bypass.
