The PTA profile is a double acting composite wiper seal composed of a filled PTFE friction ring with a sealing edge and a wiper edge,as well as two O-Rings as pre-load components. Double wiper for improvement of overall tightness, PTA is fitted preferably in combination with our Rod Seals. We recommend a bore hold for relieving pressure. No pressure release is needed for these seals with a good pump-back action. Where there is a combination of seals without sufficient pump-back capability a pressure-relieving hole is required. Morgan low friction wiper PTA is preferably fitted in combination with our rod seals OD series, B3 series or USR series
 
Design Standard
The size and tolerance of the groove and the product of the PTA Dust Ring comply with the PTI standard series of Merkel Company and WEMHF standard series of Trelleborg Company.
