I bet the other threads that are leaking are NPT threads. Its commn
and other manufacturers have adapaters, such as anti syphon and hole
adapter, filte etc to be hose threads and or pipe threads. All the
washers and thread sealant tape in the world is not gonna make a hose
thread adapt to a pipe thread.....then again you say its a Horrible
Fright kit, so with that in mind most any kind of thread is possible
from that company. As cheap as drip irrigation systems are, why did
you choose HF for a source when prices are reasonable and cheap at
major home building supply stores and online. There are perhaps 6 or
8 companies and if you do your homework, and read their online manuals
as to what fittings are and how they are sized, its a simple matter to
assemble drip irrigation and have it work..........all without leaks.
