I wonder if I placed 2 separate orders for a single “t” if it would help get the ball rolling sooner. I believe I need 2 for the reAr heat. The more I read about these failing makes me want to replace mine, but if I’ll have to wait months I’ll just buy the oem version and hope they last long enough.

Two separate single orders won’t make a difference. It’s exactly what I did because I forgot to change the quantity to 2.

Has Gruven presented a cad / 3d drawing of the prospective part?

Here's why I ask: The posted example pictures are for barbed hose ends. Not the quick connect fittings like we have. Based on the info I've gathered from this thread, it sounds like it'll be a barbed T-fitting that you slip a hose onto and clamp in the appropriate areas.

In that case, I'm really not seeing an advantage over these things, which you can grab for 10 bucks.


To put it differently, T fittings are already available. What makes their product, which is more expensive, not yet on market, no date to have on market, and without any sketches/drawings better than this?

Figure out what fitting works, get a manufacturer and part number and let us know.

The picture is of the actual design.

The problem is that the rear heater core lines are a different size which makes finding an off the shelf part more difficult... perhaps not impossible but more difficult.

Dig around at www.mcmastercarr.com. I don't know the exact hose sizes needed, but when I looked (and decided NOT to send Gruven any money) I found multiple brass, aluminum, or stainless options in tee or even wye, that look like we could make them work.

@kbuskill do you know the hose sizes and their configuration on the Tee?

The front heater core line measures ¾” OD and the rear heater core line measures ½” OD.


The 3rd fitting that goes back to the engine measures 5/8” OD.

This is why it is hard to find a fitting without using several adapters.

Seems that ID of the line is what matters. Why are you giving the OD? Or are those the OD sizes of the fitting? I’m confused.
