Review on 🔌 LUTER Straight Pneumatic Filament Fitting by Mark Dahmer

Teflon hose is quite simple. Its teflon tubing, three rolls, cheap. Exactly what I wanted for my CR3. Installation was easy, unscrew the fittings, pull out the old pipe, cut the new one (MAKE SURE IT'S NICE AND SQUARE) and connect. The fittings appeared to be much larger and better quality than stock, but after using them and playing around with the printer for 3 days I finally determined that the blue/brass plug ID was the problem. The connector side is ok, works great with the tube. The INPUT side is much smaller than the original which caused a lot of drag resulting in ruined prints. To save yourself the hassle, find a drill that fits snugly into the socket that came with the printer and use that to drill. out of the blue/brass fitting - there shouldn't be a problem after that. Unbeatable in price, let's see how durable the fittings are in the next few weeks after printing. ADVANTAGES - Cheap. Teflon hose is OK. The black/steel hot-end fittings appear to be a nice upgrade to the stock fitting. Cons - The blue/brass extruder ports look like a good upgrade and can be a good upgrade with a little drilling. TLDR; Buy this for cheap PTFE tubing and some backup fittings.
