Just received the email where he shipped today... I'm guessing they should be here by the end of the week... there are pics of the actual parts on Gruvens website now though...

Found here...

Here are his pics...

They will ship as seen with the 2 sections of silicone hose and 4 clamps.

He is sending me hoses that are a little longer so I can cut them to the needed length and let him know what length will be required to ship.

I also went ahead and ordered this metal Dorman Y-connector for the junction at the heater hose/reservoir hose/water pump so that will eliminate ALL the plastic connectors in my system so that I don't have to worry about replacing those ever again or having them crack and leak or break and leave me, or my wife, stranded.

Good work on this dude. Why no nipple flange on the inlet? Not nit picking just curious is all. Nice touch adding the clamps and hoses to the kits. I may eventually order these I just can't justify the expense right now.

First of all I would like to clarify, just for the record, that I am in no way affiliated with Gruven.

I had no part in the design or manufacturing of these other than pitching the idea to Paul and sending him some original parts (plastic T-connector, and the metal ends that they attach to) for him to use in the R&D process.

As to why there is no flange on the one end... I really couldn't say.

If I had to venture a guess, my guess would be that since there is a longer length on that section for the hose to slide over it has plenty of *********** creating more friction due to the larger surface area contacting the hose making it less likely to slip off.

Combine that with the fact that the cooling system runs a relatively low pressure, approximately 15 PSI, and the odds of it blowing off are slim.

If it makes you feel any better though, it looks like there is probably enough room to stick two clamps on that side.

In return for helping him (sending him the original parts, giving feedback on the fit and finish, install pics) my compensation is a free set of these connectors that I will get to install and take pics of for him to use on his website.

Not a bad deal, even though it has taken a lot longer to come to fruition than I expected.

I do think these will be a great product. I realize they are not for everyone, and that's ok... for me even though the price seems high it is worth the piece of mind for me to never have to worry about them breaking ever again.

Just to put things into perspective from a pricing perspective...

I just paid $42 for one CAST aluminum Y-connector from Dorman.

These are solid BILLET aluminum and TIG welded so obviously the labor involved is higher to make them VS someone casting a hundred at a time.

Sorry if that came across as rude... I was just trying to clarify my role in this matter.

It's hard to communicate effectively through text as it sometimes comes across the wrong way... lol

Washington. The desert side not the Starbucks side
Reading>me LOL

Some feedback from someone who's not ordered them, but might entertain the idea in the future:

- Smooth side is a turn off. It appears sized to fit the push to connect hose end, but without any provisions for actually securing it. Either add a barb for clamps, or add a lip for the stock heater hose. Feels half assed


- Cheap screw clamps aren't what I would expect for a product of this caliber. Either include spring clamps (preferred) or proper no-pinch hose clamps.
