PTFE Bowden Tube (1M) 1PCS+ 6pcs KJH04-M6 Fittings + 6pcs JP4-01 Pneumatic Fittings with PTFE Tube Cutter for 3D Printer 1.75mm Filament

The KHJ04-M6 connector doesn't spring up to grab the tube requiring the user to lift the connector ring to lock the boden tube in place. With all the movement of the print head I felt that a clip to make certain the connector doesn't accidentally release the boden tube needed to be used.The clips that come with the kit are too large for the KHJ04-M6 connectors but do fit the JP4-01 connectors.I designed a clip for the KHJ04-M6 connector and uploaded it to Thingiverse and named it, Boden Tube Connector Clip, if anyone is interested.All in all I think this replacement parts kit is a good value.

I can't speak for all printers but I needed to replace the tubing for my Longer LK5 pro and these fit perfect. The tubing had to be cut to size and the clipper included do a great job for that. The blue clips are pre-attached on thr silver screws so you shouldn't have to worry about trying to handle them individually. Over all super easy to work with. I was able to assemble and attach it to my printer in less than 10 minutes.

Just what I needed to repair my longer LK5. The bowden tube cutter works very well.

I would recommend this kit to everyone who uses Bowden system ! As I'll need more, I'll buy it here again.The Bowden system uses PTFE tube so the filament slides easy and reduces friction that can cause all kinds of problems when 3D printing.

I needed new PTFE tubes and this was nice since I have multiple printers. The tube cutter is a nice addition as it ensures straight cuts so no filament can escape the sides.

If you don't cut the tubes perfectly perpendicularly, filament can seep into the extruder heatsink area, which will make you sad. The cutter thing this comes with cuts it straight, which is critical.Everything else in this package is the same as you'll get anywhere else, which is good.

I had a part quit working on my 3d printer. It was the Bowden tube fitting was wore out. The replacement parts came in and fixed my issue. Great replacement parts for the price. Seller was fast on the shipping

Definitely needed the tubing and the cutter, old one was clogging when I tried to print and wouldn’t unbind in the tubing.I do like that it came with replacement connectors, but sadly they did not fit my machine. I should have checked that before buying it.Ender 3 max. Stock hot end is a mm larger than what the connectors use. Otherwise exactly what I needed. They’ll probably last me a few years since I only needed .5 meters replaced.

The tube is 3x1.5mCoolThanks

When tightening the connector it just broke off and left it's threads inside my extruder drive.Thanks a lot, now I can spend more money fixing another part that wasn't even broken.Do NOT recommend, quality is really bad if it breaks when tightening.
