Tech Specs
Product information
Nylatech MD Cast Nylon 6 Tube. Molybdenum-disulfide-modified cast PA6 for machined wear components.
Select your tube size
3–6 in outside diameter (OD). Select OD, then inside diameter (ID).
Sold each (EA): quantity 1 = one complete tube. Standard length: 52 in. Length is not a separate option.
Choosing MD
Consider MD when reviewing unfilled nylon for friction and wear requirements. Compare Natural as the unfilled baseline or MD-Oil when internal oil lubrication is also needed.
Tube is machining stock for bushings, sleeves and rings, not finished bearings or pressure-rated pipe. Nominal wall thickness = (OD − ID) ÷ 2.
Other tube grades: Natural · Natural-Oil · Blue · Oil-Filled · SL · MD-Oil · PVM · Super Black.
Allow for machining: dimensions are nominal stock sizes, not finished-part tolerances. Nylon absorbs moisture; consider dimensional change, temperature, chemicals and operating loads when specifying close-fitting parts.
