HYMAX® LARGE DIAMETER COUPLINGS

Krausz HYMAX® wide range coupling solutions feature advanced engineering and innovative design, enabling fast installation, outstanding flexibility, and extreme durability in varied conditions. These benefits make the Krausz HYMAX® the high-performance, cost-effective choice for a broad variety of applications. A revolutionary product line, that has set a new industry standard, the HYMAX products have been field-proven in millions of installations worldwide.

HYMAX unique top-facing bolts enable easy installation access while its ready-to-use, stab-on design eliminates the need for extensive under-pipe digging and work. HYMAX’s dynamic pipe deflection of up to 4° per side, reduces the risk of damage and cracking of the pipe due to ground shifts and temperature changes.

NOTE: HYMAX LARGE DIAMETER PRODUCTS SIZES DN 350 TO DN 1500 ARE USING THE 2-LAYER DETACHABLE GASKET.

 

The KRAUSZ HYMAX and REPAMAX/REPAFLEX products received approval from the SVGW Institute according to the European standard EN-14525.

  • During installation, allows for up to 4° angular deflection on each end, as well as for misaligned pipes.
  • Absorbs post-installation dynamic pipe deflection of up to 4° on each end, reducing the risk of damage and cracking due to ground shifts and temperature changes.
  • Adapts to out-of-round pipe shape (up to 13mm), for optimum fit on both ends.

HIGH DURABILITY

  • High-quality sealing solution – Patented hydraulically assisted gasket features two-stage sealing: mechanical sealing that is effective under vacuum or non-pressure; and self-inflated gasket using water pressure.
  • Fusion-bonded epoxy coating enables an insulated product and prevents corrosion.
  • Nuts, bolts and other components are made of stainless steel.
  • Innovative radial closing design and sealing systems eliminate installation errors.
  • Advanced Molecular Anti-Galling (MAG) unique dry treatment process on nuts and bolts, based on embedded zinc, preventing galling and enabling repeated bolt tightening; it also eliminates the need for grease, preventing dust and dirt build-up.
  • One- piece design delivers fortified strength and enhanced flexibility.

COST-SAVING
Read More

  • Hymax products suit a wide range of pipe diameters, replacing the need to use dedicated-range products and thus reducing inventory costs and saving shelf space.
  • Fast and easy installation saves time and money.
