A: It's a 3/8" flow plug, but the threads are a standard 1/4" NPT. Think about how to screw them into your tool (the 1/4" NPT bit) separately from the diameter of the airflow part (the 3/8" plug).
A: Hi Mike, The 3/8 Quick connects are 3/8. Husky does sell ¼" as well. You have to be careful to not get them mixed up. best, Phil
A: Take you hose and measure. There was no size on the packaging. I got one to large.
A: Hi Mike, I can't give you the exact cfm rating, but my die grinder, which needs 16 cfm, operated poorly with my 1/4" hose, operates great with the 3/8" hose and couplers. Hope this helps Best, Phil
A: The 3/8” body size couplers & plugs will allow for more air flow and lower pressure drop than the ¼” style. This will help to optimize tool performance. This kit is compatible with the 3/8" I/M Plugs.
A: Hi Todd, They are availabe from many sources, but a word of caution. There are several styles and you will need to make sure you get the exact style as you have in the kit Good luck Phil
A: These pieces are available individually.
