I have a hot-air workstation with a small CFM fan inside. I desire to modify the air-hose with a coupler, the question I have is, do these coupler leak? As the 'blower' produces low CFM, a coupler leak would significantly reduce the pressure. So, does it leak?
A: I have only seen them leak when they rust from not having dry air, or having the sealing face damaged.
