What Customers Are Saying

The Kobalt coupler/plug kit is generally well-made, with customers finding the components easy to use and providing a secure, non-leaking connection. The couplers feature six ball bearings for smooth operation. However, some users experienced compatibility issues, particularly with older air fittings, as the tight tolerance on the coupler collar made it difficult to connect certain existing plugs. The smaller diameter of the plug hole also prevented some older plugs from fitting properly. Overall, the kit is a good choice for those building up their air fitting collection, but users with a mix of new and old equipment may need to check compatibility beforehand.

Good accessories

We needed these accessories to setup our air naile for a roofing project. These worked as expected.

They seem to be quality coupling tools

Would Recommend

It did what I needed it to do with a nice snug fit. Too soon to know for sure but no complaints. Ask me again in another 6 to 12 months. Although I don't foresee any issues.

Had a bit of trouble fitting some adapters

Would Not Recommend

I felt like the female end of the adapter soundly accept all the male adapters of other tools I had. Perhaps because it’s for automotive? Seems weird since 1/4 should be 1/4. Just felt a little tight. We’ll built, just had fitting issue.
