Hallite Seals International Ltd. Rod Seals & Single Acting Piston Seals 511 Series

The Hallite 511 is a loaded U cup utilising a polyurethane or polyester shell energised by a high specification resilient O ring.At zero or low pressure, the O ring helps to increase the sealing force preventing any bypass. As pressure rises the sealing force increases and the O ring ensures complete lip actuation under most conditions.The symmetry of the seal allows it to be used on both rod and piston applications and its flexibility enables easy installation. Ideally suited for single acting applications, the Hallite 511 can also be fitted back to back for use in double acting applications.Feature s Flexible for easy installation Excellent resistance to abrasion Positive lip actuation Knife trimmed precision sealing lips Compact housing Wide range of sizeMaterialsSeal material - O-ring Standard Material:Polyurethan e (Black) - NBRLast digit of part no.10Polyester - NBRLast digit of part no.11Polyester - FKMLast digit of part no.12Hallite 361 TPU - NBRLast digit of part no.16For further information about the different 511 material variants we supply, please contact your local Hallite sales office.
