I'm quite confused by the couplers for air hoses, tools and compressors. The compressor that I am going to buy has a 1/4" outlet. The hose I bought is a 3/8" and the tools that I bought have a 1/4" inlet although they recommend a 3/8" hose. What type of connectors do I need? When I see a 1/4" or a 3/8" coupler does that mean the hose side, the connector side, or both sides? What size do I need for my setup? Do I have to buy a special 1/4" to 3/8" adapter?
My other question is about water traps and oilers. I've read that it's best to place them as close to the tool as possible. However, the ones that I have seen on HF and NorthernTool look quite large and heavy and look like they are supposed to attach directly to the air compressor outlet and not dangle from the end of the tool. Are there lightweight ones that easily attach to the tool itself? Any recommendations on where I can find one and a good brand? Thanks,
Brett
