The Morelli Telescopic Tube — .035″ is a stainless steel sleeve with a .035″ (0,90 mm) internal diameter, sized for the 0,9 mm round wire most commonly used in laboratory-built appliances. It sits between the .031″ and .055″ gauges and is used wherever an orthopedic or orthodontic appliance requires sliding movement over a wire or stem, including Mandibular Protraction Appliances (MPA) for Class II correction.
Key Features
Bore matched to 0,90 mm stock — the .035″ (0,90 mm) internal diameter is sized for the standard 0,9 mm round wire used in appliance frameworks
Mid gauge of the family — more clearance than the .031″ tube while keeping the assembly compact
Stainless steel construction — holds its shape through soldering, welding and daily intraoral loading
330 mm continuous length — enough stock to section several sliding elements from a single tube
Consistent internal bore — telescoping components travel without binding or lateral play
Pairs with 0,9 mm frameworks — matches Morelli components fabricated in 0,9 mm wire, such as palatal bars

Building on 0,9 mm wire?
The .035″ tube is the everyday gauge for standard framework wire — choose the .031″ (0,80 mm) tube for lighter stems or the .055″ (1,40 mm) tube for heavy-duty assemblies.
