Review on 🔌 Hourleey Threaded Bulkhead Fitting Connector for Hydraulics, Pneumatics, and Plumbing by Jason Taylor

However, one would assume they have a 3/4 pipe thread, which is not the case. I have several new 3/4 tube fittings, both steel and brass, and none of them will thread into any of the fittings I have more than a half turn or so. So not sure what this thread is, but it's not standard. This is totally useless to you if you need the male side to attach. The 1/2 female thread seems correct. So if you need to connect this part, this fitting should work. I haven't installed it in anything so I can't tell if it's leaking or not. I will return them.
