Piston Seal

K49 is a two piece double-acting sealing set which consists of a 60SHR D polyurethane seal ring and a NBR elastomer ring as an energizer. K49 Piston Seal's proven performance is now
enhanced with the new generation where the K49 is now made of high performance PU6005
TPU and the design is modified for higher extrusion resistance.

High Performance TPU

PU6005 is a new generation 60SHR D TPU with advance mechanical properties and wide media compatibility. Among many applications and designs, the high extrusion and abrasion resistance of PU6005 makes it a perfect choice for the face seals of the piston seal designs with and energizer. Moreover PU6005 has good resistance against mineral oils, greases, water-based fluids, and aliphatic hydrocarbons. Although the operating temperature range varies due to the elastomer energizer, between -30 °C / +110 °C, it can go up to +125 °C for short intervals.

Compatible with hydraulic, mineral and water-based fluids (i.e. HEES, HEPG, HEPR, HFA, HFC, HFDU)
