4mm Micro Irrigation Tap Adaptor

thingiverse

This is a 4 mm pipe micro irrigation adaptor for threaded tap. Includes 1 inch and 3/4 inch versions. Each adaptor has two pieces, and additional joints are also needed to avoid water leakage. About the thread pitch: notice that although threads for 1" and 3/4" are different as in UTS (https://en.wikipedia.org/wiki/Unified_Thread_Standard), in the garden shops, both are sold with the same thread pitch (corresponding to the 3/4"). This has been the design decision here. Clarification: What I name 1" is in fact 3/4" BSPF, what I name 3/4" is in fact 1/2" BSPF, there are differences between UTS and BSP (British Standard Pipe). The later defines 3/4" with a thread diemeter of about 1" and 1/2" with a thread diameter of about 3/4". Tested so far my 3/4" = 1/2" BSPF together with an electrovalve without leakage. Resin SLA print works fine in this case
