Fail-safe tube fitting I found it at a specialized hardware store. The price is cheaper than Pushfit fitting. Housing screw: – M6, pitch is 0.9mm – Length is 6.00 mm Coupling housing width: 10.00 mm Locking screw: 8.00 mm It holds PTFE tube (OD 4.00 mm, ID 2.00 mm) firmly. It eliminates the tube movement once it's secured by the locking screw. The red filament is 1.75 mm PLA. There is no restriction against filament movement. 20161004_0124.jpg mod_embed_images_loadimage('bda56e08445688fb8147c2656ebf89f6', '/forum/thumbcache/99a/ae3/952/ca9/10e/72c/4a4/a79/3f2/516/e8_800x400.png', 'https://butterflyofdream.files.wordpress.com/2016/10/20161004_0124.jpg?w=640&h=428', 'https://reprap.org/forum/addon.php?4,module=embed_images,check_scaling=1,url=https%3A%2F%2Fbutterflyofdream.files.wordpress.com%2F2016%2F10%2F20161004_0124.jpg%3Fw%3D640%26amp%3Bh%3D428', '', 711987, 800, 400, 'Loading image ...', false); 20161004_0127.jpg mod_embed_images_loadimage('b204ef622ebdc8e8bef9e4d12b8de854', '/forum/thumbcache/5ec/3e3/421/fc3/34c/e77/beb/465/594/6b8/d2_800x400.png', 'https://butterflyofdream.files.wordpress.com/2016/10/20161004_0127.jpg?w=640&h=428', 'https://reprap.org/forum/addon.php?4,module=embed_images,check_scaling=1,url=https%3A%2F%2Fbutterflyofdream.files.wordpress.com%2F2016%2F10%2F20161004_0127.jpg%3Fw%3D640%26amp%3Bh%3D428', '', 711987, 800, 400, 'Loading image ...', false); This kind of fix becomes thing of the past. cdsc_00011.jpg mod_embed_images_loadimage('875c5b48ae1d35ffb07f34e24691f971', '/forum/thumbcache/20a/2ec/f51/d3c/300/79a/35a/1ed/c0e/371/6a_800x400.png', 'https://butterflyofdream.files.wordpress.com/2015/06/cdsc_00011.jpg?w=640', 'https://reprap.org/forum/addon.php?4,module=embed_images,check_scaling=1,url=https%3A%2F%2Fbutterflyofdream.files.wordpress.com%2F2015%2F06%2Fcdsc_00011.jpg%3Fw%3D640', '', 711987, 800, 400, 'Loading image ...', false); https://reprap.org/forum/read.php?4,711987,711987#msg-711987 Mon, 13 Apr 2026 04:41:06 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,711987,712652#msg-712652 Re: Fail-safe tube fitting https://reprap.org/forum/read.php?4,711987,712652#msg-712652 stephenrc Reprappers Sun, 09 Oct 2016 11:03:26 -0400 https://reprap.org/forum/read.php?4,711987,712590#msg-712590 Re: Fail-safe tube fitting https://reprap.org/forum/read.php?4,711987,712590#msg-712590
How does the little bead "clamp" on the tube? and how did the store describe this item?

Im looking into stronger bowden couplers atm to increase print speed so im developing this double coupler, but a simple metal piece is of course nicer to work with.]]> sungod3k Reprappers Sun, 09 Oct 2016 04:52:04 -0400 https://reprap.org/forum/read.php?4,711987,711987#msg-711987 Fail-safe tube fitting https://reprap.org/forum/read.php?4,711987,711987#msg-711987
