Great threads! Exact fit, no wiggle finally! Great product.
I've been trying to find the exact 3/16 thread for a while now and finally have found it with these! Some say it's 3/16 thread, but wiggles a lot loosely. Some say pipe thread and others say compression. Make sure you get the right one. Great 10 pack for the price is spot on and quality is nice. I tightened down the threads very hard and no stripping occurred.

Solid unions
Used to fix rotten hard lines on my Subaru Outback. No leaks in two years of use. Just be sure to prepare good flared connections.

I always buy these brake unions for fixing my cars, but sometimes the threads are a bit weak, these ones are well threaded and they lock with the brake line ones . super happy will buy again when needed

I was not able to get replacement parts for my car. With these I was able to make new lines out of 2 short lines and I am back on the road for a fraction of the cost.

Very disappointed. Most of the Union Threads were such poor quality that they were unusable. Returned
