Compression coupling.

Would Recommend

This product performed as intended. It’s a compression fitting, not a pipe thread fitting.

Works well

Would Recommend

Used this to connect two water lines together. The water valve was too far for the sink and there wasn’t a supply line long enough.

Integrated ferral is horrible

Would Not Recommend

As said below, get a nut and sleeve separately. The integrated ferral is horrible to work with.
