TM lightweight hose is great when I am teaching students in one of my framebuilding classes. They are a bit sturdier than Smith's Kevlar hose and won't get a hole if a bit of melted flux falls on them. However for me personally Smith's hose is the best option. They are the lightest and give no resistance to the torch handle when moving the flame around. It is necessary to remember not to place the hose underneath what you are brazing and also to not let them rest on the floor. If one is capable of not doing those 2 bad things, they are great.

Just to be clear, the hosing combination I recommend from the flashback arrestor with a B fitting is 12 1/2' of 3/16" Type T rubber hose with B fittings on each end. This is joined with the 10' (or what length it is) of Smith Kevlar hose with a B fitting on one end and an A fitting on the other. The 2 hoses are combined with a B/B male brass connector. The A end of the hose should go into the end of an A size check valve attached to the torch handle. Somehow or another you should hang these hoses from above so they are not touching the floor.

It is unfortunate that both TM Technologies and Paige Tools have disappeared. They were convenient. Welders Warehouse in the UK seems to have diminished its inventory of their multiport tips. Looking online now they seem to have only the smallest and largest tips in stock. They sold at a fantastic price too. However their ¼” X 36 tpi threads require using a die so they can be used on Smith’s ¼” X 32 tpi threads. https://www.thewelderswarehouse.com/...s-Nozzles.html

G-tec is a supplier of propane specific mixers, goosenecks, and tips to fit almost every American brand of torch handles. Their various mixers have threads that match a specific brand of torch handle and their goosenecks and tips all have the same Victor threads so they are interchangeable with each other and any mixer. They make both multi-port and single orifice tips. Those are very similar to Victor and Gentec TEN tips except they are made of brass. Their multi-port tips are made out of brass/copper and also designated as TEN so don’t get them confused with their single hole tips. They are much bigger than what we usually use so only the smallest sizes are worth buying. In some applications, their multipart tips are like a rosebud except with a sharp center flame. This can be useful when brazing a fork crown and want the big heat to warm up the mass and still use the center flame to clean the shorelines.
