This appraisal is for a range of VIPSeal metal-banded flexible couplings with metal shear rings.
This Issue 2 is a replacement for the previous version of the appraisal which had reached its 5-year expiry date.
Shear banded flexible couplings are designed for joining or repairing pipes of various material with the same or similar nominal internal diameters in low pressure sewerage or drainage pipeline systems. Where the difference in outside diameter of the pipes to be joined is greater than 16 mm an appropriate adaptor bush is utilised to facilitate leak proof jointing.
The range of nominal diameters is DN 100 to DN 600.
VIPSeal shear banded couplings are supplied with Grade 316 stainless steel metal bands, shear rings and fasteners. The sleeve and adaptor bushes are manufactured from EPDM rubber.
The couplings are not suitable for drinking water applications.
