U-cup seal U-N6

lippedpolyurethanefor hydraulic applications

Description The U-cup N6 is a one-piece, single-acting sealing element made of thermoplastic polyurethane (TPU). It features a symmetrical U-profile that increases sealing force as system pressure rises, providing high stability against pressure peaks and excellent abrasion resistance. Standard TPU hardness is 93 Shore A; other hardnesses and colors are available on request.

Fields of application

• static
• dynamic
• single-acting
• double-acting (inactive)
• linear
• rotating (inactive)
• oscillating

Main use Predominantly for hydraulic applications where high pressure stability and abrasion resistance are required.
