What Customers Are Saying

The compression fitting is generally effective and easy to use for various plumbing and water line applications. Many customers found it to be a good value, with the right size and fit for their needs. It worked well to fix leaks or connect water lines. However, some customers had issues with the design, where the compression sleeve is integrated into the nut, causing compatibility problems and leaks, especially with copper tubing. A few customers also received items that did not match the online description or product image.

Compression ferrell is attached to nut

Would Not Recommend

Does not work with plastic lines. The ferrell is part of the nut and does not crush enough. It's listed as compatible, but it's not. Back to the drawing board.

Don't Purchase - Many Connections will Leak

Would Not Recommend

The brass compression sleeve is attached to the compression nut instead of being a separate independent sleeve. This built-in lack of flexibility resulted in several connections leaking, which then required cutting the tubing and trying again. Cost extra time and money to complete a simple project.

Compression fitting nut

Would Recommend

Used this brass compression nut with a matching brass ferule ring to attach a tube to a plumbing fixture. Tightened firmly. Tip: coat the ferule and threads with Oatey pipe dope before tightening. Old plumbers trick to make tighten easier and leak free.

Perfect fit

Would Recommend

This was a perfect fit for my refridgerator water line. I had a poly line running from the sink and needed a new connection when I moved the fridge. This was perfect. Easy to install and no leaking
