Designed to accommodate specification breaks of similar nominal pipe sizes i.e. 6in 46 matching to 6in 52 would utilise a transition seal size 46/52
As from the 1st February 2011, the new colour coding will apply. All Techlok sealrings will be coated black irrespective of the material grade. This change has become necessary to ensure that materials are not mixed up due to colour confusion in the market place.
By removing all colour coding, it will now become mandatory that all users shall formally identify the sealring material grade by inspecting the marking data which is hard stamped on the parts.
Whilst the formal marking data has always been present, there is evidence that “casual” identification using the colour has become accepted in the marketplace, this has led to confusion as not all suppliers have followed the original colour coding.
There is also evidence that colour coding has been ignored resulting in incorrect materials being fitted. During the transition period we will be ensuring that this change is well highlighted in our packaging, and other measures will be adopted to improve clarity of the marking and understanding of the material selection.
