Fittings
 
To complete the package Iplex also supplies Polyethylene pits, pit covers, collars, PVC fittings and other accessories.
 
Individual projects can require the use of specialist conduits or fittings. These are generally not available from standard product ranges and are often required in small volumes. Iplex Pipelines is the market leader in the custom adaptation of plastics technology to the design of special fittings. This capability is now available to telecommunications systems designers and contractors. Typical custom fitting requirements include supply of non-standard radius bends or production of adaptor couplings for PVC - Galvanised iron conduit connection.
