15mm White SPEEDFIT Collet Locking Clip - CM1815W - Pack of 10

Product Information

Other things you can do to improve performance include having the shortest bowden tube possible, while keeping bend radius no less than around 150mm. Initially push-fit fittings were being used for fuel systems and now they are an essential part involved with low-pressure power steering systems and aiding the development of greener engines.

The push-fit solutions can also be found in water purification systems. These food grade fittings have been designed specifically for fluid control and drinks dispensers meaning that when using water systems in offices and other public places, water is safe to drink, while systems are easy to maintain and repair. Those of you who've seen our new Gold V6 will have seen the swanky new Capricorn PTFE tubing and collet clips that it comes with. This blog post goes into more detail on the need for these upgrades, and how they work. TL;DR: Push the pipe into the fitting, up to the pipe stop. If the Speedfit Pipe has been cut correctly the insertion mark on the pipe will be level with the collet head. The ‘O’ ring on the Superseal Pipe Insert provides a secondary seal against the bore of the fitting. A good connection has been made.Don’t forget that bowden tubes can and do wear over time. Abrasive filament will gradually eat away at the inside of the tubing, and just the passage of filament with drive-wheel toothmarks on it will have an impact. Additionally, the ends where the couplings grip can get chewed up over time, but this is much reduced if you use our new collet clips. The spool weight myth is countered because you get the same no-drag effect with a direct extruder by running a guide tube from the spool holder to the extruder in the normal way, thus keeping a constant filament length between extruder and spool independent of carriage position. That’s right, plastic push-fit fittings are completely tool free. The pipe simply needs to be inserted within the fitting, where leak free connection is ensured with that same push-fit action, for which no tools are required. Because of this push-fit fittings are entirely demountable, meaning they can be disconnected and reused should a system need to be dismounted. Retractions try to counter this by “pre-pumping” at the start of extrusion and relieving pressure at the end of extrusion. The more nuanced pressure advance algorithms do a conceptually similar thing, but are continuously compensating during acceleration and deceleration. Whatever control method you use, it is not possible to gain control authority over a system that is inherently less responsive. You can compensate for the errors to an extent, but you can’t eliminate them. Your extruder has a finite amount of speed and acceleration which it can use for compensating.

You just need to increase retraction and your bowden system will be as precise as a direct extruder"Collet covers for use with standard Speedfit fittings, are available in white or in red or blue to allow colour coding of pipes. Friction in a standard v. Capricorn bowden tube: More friction in the tube means less force pushing filament through the HotEnd

Of course, tools need to be used to cut pipes to size and ensure for clean connections between pipes and fittings, but to create the connection itself – no tools are required. The amount of “stuff” on the print-head is much lower, and takes up less space. This can mean a smaller print head, a larger usable print volume, more extruders on one print head, or any combination of these factors.We have a new high-performance bowden tube , and ways of making our tube couplings grip the tube more securely using a pre-tensioning clip . These will make your bowden system more responsive and reliable. Read on to find out how. What is a bowden system?
