Keep Your Air Tools Clean
An improvised cap goes on and comes off easily, and doesn’t allow dirt to get into the tool.
I own dozens of air tools and I try to keep them clean and in good condition so they don’t fail me when I need them. I think every air tool should have its air inlet capped when not in use. My solution is rubber automotive fuel line. It’s strong, durable, and flexible.
I use the 5⁄16-in.-inside-diameter-size fuel line for most all of my tools, but some require a larger-diameter line to fit over the inlet fitting. Cut off a length about 2-1⁄2 in. long and squirt silicone caulk about 3⁄4 in. deep into one end of the line, completely filling the hole. When the silicone is dry, slip the open end of the fuel line over the air fitting. You’ll find the improvised cap goes on and comes off easily, and doesn’t allow dirt to get into the tool.
