Fluidra - Collector Arm Link Coupling 1" (Pack of 4)

Fluidra – Collector Arm Link Coupling 1″ (Pack of 4)

This genuine Fluidra AstralPool 1″ collector arm link coupling is an internal PVC connector designed to join extension collector arms to standard collector arms inside large-format pool sand filters. Supplied as a pack of four units, it ensures a secure, leak-free connection within the filter’s lower manifold system. It is an essential spare for maintaining proper water distribution during both filtration and backwash cycles.

Compatibility

This coupling is a direct genuine spare part for the AstralPool Berlín Ø900 mm and Vesubio series large sand filters, including the valveless filter with a 35,000 l/h flow rate (Ø950 mm tank, Ø75 mm outlets). Always verify your filter model and collector arm thread size — a ¾” variant is also available for smaller manifold assemblies.

Why genuine matters

As an original Fluidra part, this coupling is manufactured to exact dimensional tolerances for a perfect fit on AstralPool collector arms. Using genuine components ensures the manifold maintains even water distribution across all laterals, protecting filter media and prolonging the service life of the entire filtration assembly.

Installation

The coupling slots between the standard collector arm and its extension arm, securing position 7 in the filter’s exploded parts diagram. No special tools are required, but it is advisable to shut down and depressurise the filter completely before replacing internal manifold components. Professional installation is recommended for first-time servicing of large commercial-grade filters.
