The clutch is not of the same quality as in the photo.

The fittings I received are NOT those shown in the pictures. The ones in the photos show FUSUN 4 printed on a black connector but the ones I received are NOT printed on plastic. DONTs are made very cheaply and are notorious for not releasing when they should and the extruder often breaks releasing filaments that collect everywhere. They'll work for a while, but that's all I can give them. Choose WITBOT instead.

Pros
  • PTFE hose Outside diameter: 4 mm. Thread: 6mm
Cons
  • Cord is shorter than others

Exactly what I needed and wanted: 1/8 " British Standard Pipe Thread for 4mm pipe

Exactly what I want and need is a 4mm fitting with 1/8" BMP pipe thread. The name says M10 and for tubes the pitch is usually 1mm but it is not. For 3D printers, one of the most popular threads is 1/8 BSPT/ISO 7 -1. Between positive success stories and one reviewer claiming it's not really an M10, I bet the description and bought it anyway: a success! "M10" in the description is wrong, but the flat faces fit a 10mm spanner For Use: Some PTFE tubing grips too well for my liking Time flows, once…

Pros
  • 10 x PC4-M10 Pneumatic Straight Quick Connector for E3D-V6 Long Range Extruder Bowden Extruder 3D Printer
Cons
  • Yes other interesting options

Only 6 out of 10 connections work.

This supplier put wrong plugs in first and sent PC4-M6 plugs instead of PC4-M10. The next day I received a new batch of correct connectors but after seeing some chrome plated parts in my bag I started testing each connector to see if it would actually snap onto the Bowden tube and found that only 6 out of 10 connectors would work. The other 4 didn't hold the hose at all, so this is a big mistake in the quality control of the connectors chosen. Not very happy with the plugs supplied but they…

Pros
  • Top (black) can be inserted 4mm PTFE tubing and self-locking
Cons
  • Not sure
