Looking for 3/4 GHT fittings for plumbing hookup.

[dbhosttexas]

I am hoping y'all might be able t help me find what I am looking for...

I need Plastic / nylon fittings to accomplush what I am trying to do.

I am using 3/5" ID x 1/2" OD tubing. I need to adapt to 3/4 GHT to connect to the quick disconnect fittings.

The idea here is QD at the end of hose input to the hot water heater, I will use 1/2" ID 3/4 GHT hose and filter feeding into it.

From the pump I need a 3/8" ID to 3/4 GHT Male fitting.

FROM the heater, I want a 3/4 GHT to 3/8 barb fitting, and then the other side 3/4 GHT to 3/8 barb. One side male, one side female. I would like a GHT Y fitting with shutoff valves, then more hose over to the shower tent. I want to go into the tent at 1/2", So I need 3/4" GHT Female to 3/8" barb. Again the idea here is to attach the QD there.

So end goal is, input, heater attaches to side of camper in use, output to Y, one side to a standard sink sprayer, other side to shower head / ensuite...

I would love to be able to go with a thread on barb like what Camplux uses on the shower head hose.

What advice do you have for me to set this up?
