The link you have on the BOM for this part below takes me to Male not Female ( 4pcs 1/4" Hose Barb to 1/8 NPT Male Brass Quick Coupler Air M Type Fitting Quick-Connect Fitting)
Line 31 - Hose Barb to (1/4" barb to 1/8 NPT Female) Hose to solenoid and hose to brass tee fitting
Is that correct?
I think you may just have “Female” in column B where it should be Male. Drawing page indicates “Male.”
I’ll order where the link takes me for now.
For the Part Line 32 - Barbed Hose Reducer (1/4" to 3/16") Connecting hose to suction cup Amazon 8 $1.75 $14.00
The Amazon Link is * Size: 1/4" to 1/8". https://www.amazon.com/gp/product/B088LZBWGT/ref=ox_sc_act_title_9?smid=A8MNP250PQWWH&th=1
Should the size be changed in your drawings? Or should there be a different Amazon link for 1/4" to 3/16" part?
My apologies, the link is correct but the name is wrong. It should be male as indicated. I have the made the correction in the BOM.
The port on the suction cup is a non-standard size. You get the best fit with a 3/16" barb, but 1/8" works as well.
