The notchless die drawn corners on Wrekin pressed tops gives the following benefits:

  • No sharp exposed edges
  • No cut exposed edges improve corrosion resistance
  • Continuous surface seal – better for avoiding water ingress and odours

double seal access coversThe double seal is achieved by a unique captive ‘O’ ring gasket under lateral compression in a specially designed lipped channel enhanced by the continuous surface of the cover at the corners. A second seal is achieved with an additional neoprene gasket vertically compressed in a channel. This double seal provides an enhanced level of resistance to gaseous and/or liquid ingress and/or egress under normal atmospheric pressure.
