If you work with air tools, this Forney leader hose is one of those simple accessories that makes a huge difference. At 18 inches long with 1/4-inch male NPT fittings on both ends, it's designed to absorb those sudden shock loads that air tools create when they start up. Without this protection, those shocks can wreck your air hose couplers surprisingly fast.
The construction is solid with a max working pressure of 300 PSI - plenty for most shop applications. It connects right between your air tool and your main air hose, taking the beating so your more expensive components don't have to. Forney has been making quality metalworking products since 1932, so they definitely know what they're doing.
Just remember - this is for air use only, not liquids or other gases. It's one of those 'why didn't I get this sooner' shop essentials that extends the life of your air tools and hoses. If you're tired of replacing damaged couplers or dealing with air line issues, this simple leader hose could save you money and frustration down the road!
