Hydro-Rain HRM 100 Manifold

Hydro-Rain HRM 100 Manifold

Product Description

HydroRain is truly "Built for Speed". The HRM 100 manifold components have a true 1" ID (inside diameter) and ultra smooth core to minimize friction and maximize flow. HRM 100 multi-outlet manifold components are tough, green - no glue or primers needed, and quicker and easier to put together than standard PVC manifolds. The buttress swivel connections with over-size O-rings are fast and allow more torque for a leakproof hand tightened seal. This will save installation time and money. Built to the highest industry specifications to ensure you’re getting watertight seals the first time, every time. 

Do not use teflon tape, pipe dope or glue on buttress thread connections.
