The Set: 2x Nut, EPDM Gasket and Female Adaptor 1-1/4″ provides a highly efficient and heavy-duty mechanical connection kit for modern commercial and high-capacity domestic hydronic systems. Installers utilise this dual-adaptor hardware set to create a secure, demountable bridge between primary 1-1/4″ distribution pipework and main manifold headers, low-loss headers, or plant room pump groups. Consequently, the configuration provides a streamlined solution for transitioning fluid streams while allowing individual components to be uncoupled effortlessly during future system servicing.
Furthermore, the premium brass and high-grade metal components deliver outstanding structural resistance against intense thermal expansion, extreme system pressures, and aggressive chemical water treatments. The inclusion of commercial-grade EPDM flat gaskets ensures an airtight, elastic seal that absorbs continuous hydraulic vibrations without weeping. Additionally, the free-spinning 1-1/4″ captive union nuts allow for perfect flush alignment during installation. Therefore, you can complete primary mechanical hookups rapidly while ensuring long-term, leak-proof system operation.
Key Technical Features
- Dual Modular Connection Set: Supplied as a complete matching set of two union nuts, female adaptors, and high-resilience gaskets. Consequently, it covers both the flow and return channels of a primary heating zone in a single package.
- Heavy-Duty 1-1/4″ Sizing Profile: Precision-engineered for high-volume hydronic networks requiring unhindered flow dynamics. Therefore, it prevents operational bottlenecks and optimises the efficiency of large radiant or heat pump loops.
- Premium EPDM Flat Gaskets: Features high-performance ethylene propylene diene monomer (EPDM) sealing washers. As a result, the joint provides exceptional resistance to hot water ageing, oxidation, and localised pressure drops.
- Independent Captive Union Nuts: The free-spinning 1-1/4″ nuts rotate independently of the female adaptors. Additionally, this flexible layout allows you to tighten the plumbing joint securely within confined utility cupboards without twisting rigid pipework.
- Corrosion-Resistant Metal Housing: Manufactured from premium, robust metal alloys designed to withstand continuous exposure to system moisture and heat. Subsequently, the components safeguard your mechanical room infrastructure from material degradation over decades of service.
