just works
Machining and material quality were better than expected. Edges were clean with no burrs, and the dimensions were consistent — everything lined up without needing to force or modify anything. The material feels like proper spec, not soft alloy, and it handled torque without deforming. Installed smoothly and performed exactly as intended under real load. Solid, reliable part if you’re doing actual mechanical work

Great Upgrade
I love that this is metal vs. the plastic factory ones. Fits like OEM. Let’s just hope the quality of the o-ring is good and lasts a while. Only time will tell. For now, this is working great with no leaks.

Solid upgrade.
Utilized this to upgrade my truck's cheap plastic heater hose connections. Very solid and reliable. No more worries of coolant leaking out at cheap oem failure points. Very easy to install and highly recommended.

Perfect replacement for my 2010 tahoe!
Started to notice a bit of coolant leak only to find out it was the heater hose T connector. Very common on these vehicles because of their factory plastic T connectors, they start to crack and even break off. That’s where dorman comes in with these metal ones! Sure plastic ones are much cheaper but why set yourself up for future failure again? Installation can be a bit annoying but once the old connector is off, this one goes in easily and fits perfectly!

Excellent upgrade
this totally saved my bacon amazon says this will not fit a 2017 tahoe and it absolutely will. I was doing spark plugs on my tahoe when I noticed the plastic heater T starting to leak these have been on the truck for about three or four months now and no issues to report. they were a little difficult to install but was able to get them on with a little bit of lubricant.

Fits perfectly 07 Escalade
Worked perfectly, a bit of an annoyance to install but it fits perfectly and is well worth the money over the plastic ones. Sealed up nice and tight, and is peace of mind going down the road.

Worked perfectly.
Worked the way it is supposed to. No more coolant leak now. Little hard to remove old part due to space, but not difficult.
