Product information

Nylatech MD Cast Nylon 6 Tube. Molybdenum-disulfide-modified cast PA6 for machined wear components.

Select your tube size

31–40 in outside diameter (OD). Select OD, then inside diameter (ID).

Sold each (EA): quantity 1 = one complete tube. Standard length: 26 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.
