The Roll2Seal® bore seal cap is a sealing solution developed by Parker Prädifa for easy and effective closure of bores in non-pressurized applications. The clever design combined with an innovative assembly process enables simple and accurate installation of the seal, which rolls into its seat undamaged and without a lead-in chamfer. Roll2Seal® is both self-retaining and removable, allowing for repeat installation. By means of Finite Elements simulation the required geometry can be adapted to the desired bore diameters and the assembly processed checked. The effects of varying friction conditions and material properties can be predicted as well.The selection of the material depends on the thermal and mechanical requirements, starting with PA6.6 for the seal carrier and NBR for the triangular seal as the most cost-efficient choices. The sealing system, consisting of a plastic or metal cover and the seal, is available in pre-assembled form if desired.
Product Benefits:
Innovative geometry
No lead-in chamfer
No deburring
No lubrication required
Self-retaining static seal
Removable
Seal is immune to unbroken edges of the bore
Metal or plastic cover
Available in pre-assembled condition
Easy installation
Suitable for repeated and overhead installation
Space- and cost-saving
Range of Application:
Roll2Seal® bore seal caps are found
where bores already exist for subsequent installation of additional component assemblies but require effective temporary or permanent sealing (e.g. for test runs or shipping),
where lubrication during the assembly process is not possible and
where non-pressurized systems require reliable sealing without screw connections.
