DEKS Stainless Steel Gibaults (or Gibault Joints/Couplings) are versatile pipe fittings used to connect or repair pipelines made from the same or different materials such as PVC, ductile iron (DI), asbestos cement (AC), cast iron (CI), or steel. The gibault design incorporates an EPDM rubber gasket positioned inside a metal barrel and tightened by stainless steel bolts and nuts, ensuring a watertight joint that allows minor angular deflection in water supply, wastewater, irrigation, and industrial pipeline systems.
The Gibault serves as an important solution for both new installations and the repair of pressurised pipelines, particularly where welding or solvent cementing is not feasible. DEKS offers two barrel-length versions, including Long Barrel and Short Barrel, both WSAA approved and suitable for pressure-rated applications, with size options ranging from DN80 to DN450.
Key Features:
Joining Versatility: suitable for DI, AC, PVC, CI, and steel pipelines
Sealing Mechanism: the EPDM gasket is compressed by metal end rings, creating a watertight seal while allowing minor angular deflection to accommodate vibration, ground settlement, or surface loading
Robust construction: a 316 stainless steel barrel combined with an EPDM gasket provides durability and corrosion resistance
Pressure capability: suitable for pipeline systems with working pressures up to 16 bar / 150 psi
Applications: Widely used in water supply networks, irrigation systems, wastewater lines, and industrial infrastructure
With their compatibility across multiple pipe materials, reliable sealing characteristics, and suitability for high-pressure operation, DEKS Stainless Steel Gibaults provide an effective means of connecting pipelines in water infrastructure, irrigation, and industrial systems. Available in sizes from DN80 to DN450 and in both Long and Short Barrel configurations, the range supports flexible installation requirements and maintains consistent performance under varying operating conditions.
