I'm putting a faucet in my campervan. The kitchen faucet that I purchased https://www.amazon.com/gp/product/B00X0LKYV6/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1 only has one inlet with 1/2" threads. It came with a short braided connector. The connector easily screws onto the faucet and to seal, there is a rubber seal in the bottom of the fitting. Is this type of fitting called a compression fitting? I thought compression fittings used sleeves. The employee at the plumbing supply store said that the faucet threads are 1/2" MIP. I was curious and tried to put a 1/2" FIP fitting onto the faucet and it would only go on about a turn. I understand that to get a seal with pipe threads, a sealant is used and the threads actually deform to make the seal. I also read about straight and taper threads and got a little more confused. I'm not really sure what threads the connector uses or the faucet for that matter. Maybe someone can explain it to me. Now, I am attaching the connector to a FloJet pump that has 1/2" plastic MIP threads. I need a much longer connector than the one that came with the faucet and have found these 2: 1. 1/2 in.
