Ex-stock flange drillings are available in the following sizes:

  • Table D flanges
  • 10/3 flanges
  • 16/3 flanges

Manufactured to the highest standards!

Truco supplies its full range of flanges, from 40 mm to 1 000 mm nominal bore sizes, according
various specifications of safety and durability, including SABS 1123.

Furthermore, Truco warranties its entire range of flanges against quality of material and bad workmanship.

Truco utilises the ‘drop forging’ method in the manufacturing of its flanges. Drop forging, where a
hammer is "dropped" onto the flange to deform it according to a specific shape, results in an
improved microstructure and stronger flange with better fatigue resistance – ultimately adding
strength and an assurance of longevity to your Truco flange.

Simple, fast pipe connecting!

Connect our flanges to any new or existing pipe system!

Our range of flanges serve as a joining or connecting piece for pipelines, where the connecting pipes also have flanges that
connect together through a simple bolting process. This simple process enables fast and durable installation!

Reusable split flanges


Made from a high-grade, corrosion-resistant aluminium alloy, the Truco’s
reusable split flange coupling consists of two halves with an internal helix,
which correspond to the spiral on the outside of the rubber hose. The
couplings are designed for fast, simple fitting and require no special tools.

The product is ideal for connecting new hoses or joining hoses to steel pipes
or for joining a rubber hose to HDPE pipe, as the hose can be cut to length on site.


  • Working pressures of up to 1000 kPa
  • Higher pressures using two flanges in tandem
  • Available for hose sizes ranging from 50 mm to 610 mm in internal diameter

Additional benefits

  • Eliminate the need to stock various hose lengths with built-in flanges
  • Reduce downtime in operations
  • Compatible with all major flange standards
