Great Long-Range Connector

As a result of my tests, I determined that this connector is perfect for long-range printing. The air flow is smooth and consistent, and it holds up well over time. Although the price is a bit higher than some other connectors on the market, the quality more than makes up for it.

Pros
  • Smooth and consistent air flow, holds up well over time.
Cons
  • Higher price than some other options.

Doesn't hold PTFE tubing well

I keep my filament in a cereal container dry box and use these connectors for teflon tubing from from the dry box to the printer. Due to the nature of my build, if my dryer is too close to the printer, the PTFE hose will push the hose further and further into the bin as I pull it back, causing failures. You get a lot for what you pay, but the internal teeth that grip the hose are weaker than the fittings that came with your printer.

Pros
  • Easy to use: top (black) fits into PTFE tubing and is self locking
Cons
  • Could have chosen a newer model

The hose is easy to insert, difficult to remove

I installed these on my Ender 3 Pro and they held the teflon tubing well - too well. When I had a clog and had to pull the hose out to free it, I couldn't pull the hose out without cutting it open and replacing the entire coupler. According to reviews, some connectors have a latch that requires you to push forward and then pull back to remove the hose. which you can't do if there's no room to move forward (ie - the tube is in the correct position relative to the nozzle). They are great and last

Pros
  • Application: Good fit and high performance effectively prevent blockages! Max operating temperature 280โ„ƒ
Cons
  • Cable is shorter than other picks
