Ductile Iron Dimension Joints
Our ductile iron dimension joints are designed to compensate for longitudinal dimensional variations during pipe installation, solving the problem of pipes cut short or long on site. One end of the fitting is fixed, while the other incorporates an axially adjustable sliding socket that allows precise length adjustment without cutting, welding, or special fabrication.
Manufactured to ISO 2531 / EN 545 in high-grade ductile iron, the dimension joint maintains full pressure integrity while offering a flexible, watertight connection. It is the practical choice for trench installation where precise measurement is difficult, and where fittings, valves, or precast structures require exact alignment.
- Size Range: DN80-DN2000
- Axial Length Adjustment — Sliding socket compensates for pipe length tolerances and field cutting errors.
- No Cutting or Welding — Precise fit achieved by adjustment, not fabrication, saving installation time.
- Superior Material — Ductile iron body (GGG50) per ISO 2531 / EN 545.
- Pressure Ratings PN10 / PN16 / PN25 / PN40 — Available in pressure classes to suit municipal and industrial duty.
- Leak-Tight Sealing — EPDM rubber gaskets per EN 681-1 under full working pressure.
- Flexible Connection — Accommodates minor deflection while maintaining a secure joint.
- Corrosion Protection — 250 µm fusion-bonded epoxy coating, potable water approved.
- 100% Hydrostatically Tested — Pressure-tested before shipment.
- Ideal for Difficult Installations — Perfect for trenches, valve chambers, and connections to precast structures.
