380V/220V Heating Tube Thermocouples For Automatic Edgebanding Machine Parts

Replacing a dead glue-pot heater on an edgebander comes down to three numbers: diameter, length and voltage. This listing publishes all three, in five ready combinations: 8×135 mm at 220V or 380V, 12×128 mm at 220V or 380V, and 12.7×128 mm at 220V. The tube is stainless steel with a high-temperature lead wire, supplied new, with custom size, voltage, power and lead length made to order. If your pot bore measures one of those three diameters, this is the drop-in part.

A glue pot that runs cold halfway through a shift is almost always a heating-tube problem, and most shops meet the same three obstacles: the element fails with no warning, the replacement arrives in the wrong diameter and rattles in the bore, or the whole glue unit is pulled off the machine when only the tube was worn. None of those three puts an edge on a panel.

This listing is the tube itself: a glue-pot heating element in a stainless steel shell with a high-temperature lead wire, published in five size and voltage combinations, 8×135 mm at 220V or 380V, 12×128 mm at 220V or 380V, and 12.7×128 mm at 220V. Diameter and length decide whether the rod seats in the pot bore, so both are printed per combination instead of being hidden behind a generic range.

The tube is made for strong electrical and thermal conductivity, which is why the listing quotes fast heating, energy saving and high thermal efficiency instead of one headline wattage. Power is set per order, together with size and voltage, because the wattage a glue pot needs follows the pot it heats.

Every tube is new, and custom size, voltage and power are supported; lead wire length can be made to order too. One fitting note from the maker: the rod and the mold should sit tight, with no air gap.

What the part is, and what the listing actually commits to.

• Stainless steel tube — the outer shell is stainless steel, so the tube takes repeated heat cycles in a glue pot.
• Five size and voltage combinations — 8×135 mm and 12×128 mm in 220V and 380V, plus 12.7×128 mm in 220V.
• High-temperature lead wire — the lead is a high-temperature type and its length can be customised to reach your terminal block.
• Fast heating — specified alongside energy saving and high thermal efficiency, the other two stated properties of the tube.
• Strong electrical and thermal conductivity — the tube moves heat into the pot wall quickly instead of warming the air around it.
• Glue-pot application — sold as an edgebanding machine spare part in the woodworking machine accessories group; this is the tube that sits in the gluing pot.
• Custom size, voltage and power — send the size, voltage and power you need and the tube is made to that combination.
• New condition — every tube ships new; nothing here is reconditioned or pulled from a scrapped unit.
• Fit stated as a rule — the maker asks for a tight rod-to-mold fit, so diameter and length are published per part.
• Diameter printed per part — 8 mm, 12 mm and 12.7 mm are listed as plain numbers, so a caliper reading maps straight onto an order line.

When a glue-pot element dies, the usual options are an outside repair, a generic tube that may not fit, or a part matched to the bore.

• You order by bore, not by guess. Three diameters, 8 mm, 12 mm and 12.7 mm, and two voltages are printed on the page, so you compare a measured bore with a real number.
• One spare shelf covers both voltages. Because the same diameters exist in 220V and 380V, a mixed machine floor needs one spares bin, not two.
• Fit is treated as a specification. A tight rod-to-mold fit is the maker's own rule, so the tube is meant to touch the pot wall instead of heating an air gap.
• Lead length is yours to set. A glue-pot terminal is rarely where a stock lead ends; a custom length removes a splice from the hottest part of the machine.
• Wattage is matched to your pot. Size, voltage and power are quoted together, so you are not forced into a wattage picked for another pot.
• Stainless steel where it matters. The shell is stainless steel and the part is new, so the first heat cycle behaves like the one after it.
• Spares from one shelf. CNC vacuum accessories, vacuum pods and suction plates, chain pads and bracket rollers come from the same supplier.

It fits if your pot bore measures one of the three published diameters: 8 mm, 12 mm or 12.7 mm, with 135 mm or 128 mm of heated length. Measure the old tube's outer diameter and length before ordering; a tube that is 0.5 mm undersize will still slide in and will still underperform.

Five ready combinations: 8×135 mm at 220V or 380V, 12×128 mm at 220V or 380V, and 12.7×128 mm at 220V. Anything outside that list is a custom order, which the listing supports.

Take the value marked on the tube you are replacing. The two versions are the same physical part with a different element, so mixing them up is the one mistake that will not show up until the pot is switched on.

Yes. The lead is a high-temperature type and its length is customisable, so you can state the run you need to the terminal block instead of accepting a stock length.

Yes. Custom size, voltage and power are supported: send the size, the voltage and the power you want and the tube is built to that combination, lead wire length included.

Fast heating is one of the three specified performance properties, but no heat-up time is published, because it depends on the wattage you order and the mass of the pot around it. Quote your wattage and pot size and the answer stops being a range.

Because the maker's own instruction is that the heating rod and the mold must sit tight. Any air gap between tube and pot wall becomes a thermal resistance, and the element keeps drawing current while the glue stays cool.

Send the size, voltage and power you need plus the quantity. Price is quoted against that combination rather than published, and shipping runs by air, by sea or by express.
