Product information

Nylatech Super Black Cast Nylon 6 Tube. Black, heat- and UV-stabilized cast PA6 with heat-stabilized Blue properties.

Select your tube size

14.5–18 in outside diameter (OD). Select OD, then inside diameter (ID).

Sold each (EA): quantity 1 = one complete tube. Standard length is 26 or 52 in, fixed by the OD/ID combination; confirm the selected length. Length is not a separate option.

Choosing Super Black

Consider Super Black when black colour and heat/UV stabilization are required. Compare Blue when UV stabilization is not required, or Natural for general service.

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 · MD · Oil-Filled · SL · MD-Oil · PVM.

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.
