Schedule 40 low pressure 1/2-inch PVC pipe mini-tee and endcap

thingiverse

This is work in progress. These fittings are for low pressure hydroponic manifolds for direct spray irrigation. This allows using much lower power pumps than atomizing setups, for example a 5V 1.3W USB1020 pump is strong enough to spray 8 and possibly more net pots. See my thing 4779690 for AeroGarden compatible slots. Tee and cap are press-fitted, no need for bonding. I only tried with the gray pipe, but these should work with all schedule 40 pipes, white PVC pipe is tested for 120psi but for low pressure systems grey and white PVC pipes should be identical. EndCap has space for internal 3mm x 15mm screw that does comes in conctact with water. Tee needs 7/16" hole on perpendicular piece that it press fits into. update: the end caps may be a little problem since different sch40 pvc pipe manufacturers have different inner diameter specs. Inner is never mated to anything, so it is not a problem. I will redesign my end caps for outer diameter. there is a problem with end cap, it is too loose. originally was too tight, I lowered the diameter and printed a dozen before realizing its too loose. they can be used with one layer of electrical tape strip, so I will update it later after I run out.
