Review: Does not fit 3/4" female copper fitting - I had some problem with threading. Does not fit 3/4" npt female copper fitting.You can onlyscrew in about 3 threads which means it leaks no matter how much teflon tape is used. Review: Threads don't fit - Just got it - in 6 days (good time, considering that it came by parcel post from China) - and the thread doesn't fit in the 3/4" copper fitting I'd bought for it to screw into. The thread measures about 14 TPI, as it should, but either the diameter is wrong or the thread is just enough off so that it won't fit into a standard Home Depot 3/4" Cu female fitting. I guess I'll try to find a die and fix the thread, but ...??? Anybody else have this problem?? ## Features - air vent valve, 3/4" - Technical Specifications: 1, Nominal pressure: 1.6MPa 2, Working Medium: Water 3. Temperature 0 to 110 Celsium Degree. - 1.
