Good fit. We will see how it holds up after use.

I bought this to replace a cap on a radiator on 1996 Chevy Silverado c1500, seems to be good quality and fit perfect.

This cap worked perfectly to replace the old crusty one causing a coolant leak on my Saturn. Rubber was supple, easy to install. Wish you could buy in packs of one for cheaper though since that’s all you need.

These caps fit on the metal bar I had for my circular saw extension table

Good quality rubber cap but 5/8 is the OD not the ID.

I installed these as a stop gap while I replaced the heater core in my Mustang. They are simply non-reinforced rubber caps, nothing special. I was afraid to use the car because I'm paranoid and I didn't want these to fail and leave me stranded so it made me get the heater core done faster. But they worked fine and did what I needed them to do.

Buy these for the coolant bypass on a converted 47RE to NV4500 swap. Get that trans cooler out of there it is a waste of space and cap it with these. Highly recommended

Not much you can say about bypass caps but the quality is good.
