Universal Couplings

Group 1 1
Group 1 1


Our universal product family is a wide range of Couplings and Flange Adaptors designed to join pipes of different outside diameters (OD) with the same or different nominal bore. 

Due to the wide range tolerance on outside diameter (Up to 25mm), a single LAMINAR Universal Coupling can join ductile iron (DI), steel, UPVC, cast iron, AC and other rigid pipe materials. This makes choosing the right product easier and reduces the stock holdings to the minimum. This feature of LAMINAR Universal Couplings to join different pipe materials with different OD’s is an optimal choice for repair and permanent solutions.

The corrosion protection scheme for our Universal range is available in Fusion Bonded Epoxy (FBE), Epoxy paint and Galvanized finish as standard. Other coatings options are available on request.

LAMINAR Universal ranges have applications in the transmission of potable water, wastewater and sewage, as well as in the marine, mining, oil, gas and general industrial sectors. 

LAMINAR Universal Gaskets, EPDM or NBR materials, are designed to provide a leak-tight seal while allowing thermal expansion and contraction of the pipe up to 5mm per gasket. However, lubrication with a suitable, non-toxic soap solution is advised to facilitate the installation and avoid any potential damage due to load while seating. LAMINAR Universal range of products can be manufactured with double or full sleeves to prevent end pullout on PE and GRP pipes.
