Eurac Couplings

Eurac Couplings

Eurac Couplings are used to connect unthreaded or threaded pipework by providing an equalised pressure seal to the entire surface area without distorting the wall. They are available in galvanised steel, stainless steel and come with zinc plated bolts. Type H, 3 bolt Eurac couplings are supplied as standard, complete with a white food quality Nitrile gasket with eyelets for electrical conductivity. We also offer a 4 bolt version upon enquiry. 


Eurac couplings are used in pneumatic conveying (diluted and heavy concentration light particles), vacuum or pressure systems.

Key Features

  • Temperature: -30°C to +110°C (with white food quality white Nitrile gasket).
  • Effective way to connect unthreaded or threaded pipework.
  • Easy to install. 


Number of Bolts:  3 (as standard), 4 (upon request)
Material:  Galvanised steel (as standard), stainless steel (upon request)

Note: Stainless steel 304L couplings are also available upon request. Please replace the 'G' with an 'S' in the product code respectively. 4 bolt couplings are also supplied, please change '3B' to '4B' in the respective product code.

Note: We also offer Type L, Type M, Type HX and Type HL Eurac couplings. For more information please enquire.

Eurac Coupling Gaskets

Eurac Coupling Gaskets

Eurac coupling gaskets are available in a range of materials as shown in the table below. White food quality nitrile gaskets are supplied as standard with Type H couplings and come complete with eyelets fitted to support conductivity.  Please note: replacement gaskets are manufactured without eyelets as standard.  If you require eyelets or earthing strips, please specify at point of enquiry.
