Review on CEKER 1/4 Od X 1/4" NPT Thread Male Push To Connect Air Fittings + 10Pcs 1/4 Inch Tee Union Tubing Fittings by Kenny Donald

I recently tried the CEKER 1/4 Od X 1/4" NPT Thread Male Push To Connect Air Fittings along with the 10Pcs 1/4 Inch Tee Union Tubing Fittings, and my experience was mixed. On the positive side, the fittings were easy to install and seemed to hold up well over time. The tee union tubing fittings were also useful for branching off the main air line to multiple tools. However, I did experience some issues with leaks. I tightened the connections as much as I could, but air still escaped. I had to use extra tape and sealant to finally get everything sealed up. Overall, the CEKER air fittings and tubing connectors are decent, but not without their faults. They get the job done, but require extra effort to prevent leaks.
