Saipor V6 Stainless Steel Throat Tube with Teflon(6pcs), All-Metal Hot End 1.75mm for E3D V6 Makerbot Reprap 3D Printers Accessories

I bought an all-metal genuine E3D V6 hot end for my Monoprice Select Mini V2, but I just didn't get on with the metal throat without the Teflon tube (spent hours trying everything suggested online but all prints eventually failed due to jamming/clogging).Anyway, decided to go back to a lined throat as I only print with PLA. These looked like a straight swap for the genuine E3D so got them the same day with Prime. I'm currently finishing my first print with these - no leaks, no heat creep and fits the genuine E3D V6 perfectly (exact same size as the original throat).The Teflon on some of them has been cut a bit poorly (not square) so I'd recommend putting a new sharp blade in your Stanley knife and gently refining it a bit first if you get the same issue. For the price I paid though, not an issue, can't expect the world for £6! Cheers!

Cheap throats for a printer with a ptfe lining. Not too much to say other than they have worked pefectly well through a couple of rolls of filament.

Just what I needed. No more clogging now.

Not so good

Purchased as I was getting constant hot end clogs that I traced to 'over upgrading' the bimetal heat breaks I'd fitted were unnecessary for printing PLA and allowing the material to stick. These throats are lined with PTFE and immediately resolved the problem, I'm currently using them with a V6 & a MK8 hotend and they've worked perfectly with PLA, PETG & TPU without a single clog. Be careful when changing the nozzle not to lose the PTFE liner and be careful about the maximum temperature (depending on exact composition PTFE can start to degrade between 230˚ to 260˚ and releases some pretty toxic gasses). A cheap and very effective upgrade for reliable printing.

Le filettature sono buone, le gole funzionano.
