DanaPneu P04 – wear resistant in dry air

DanaPneu P04 made of wear resistant UHMWPE is highly wear resistant even when running in dry air. Typically, several times longer service than when using advanced PTFE seals. DanaPneu P04 is available in standard UHMWPE DanaFlon 91 and the new temperature resistant UHMWPE DanaFlon 98.
For very high temperatures P04 is available in PTFE compounds like DanaFlon 16.
