AstralPool - 1½" Threaded Union Set for Boreal Filter D400 - R0598200

AstralPool – 1½” Threaded Union Set for Boreal Filter D400

This is the genuine AstralPool 1½” threaded union set (position 8 in the official Fluidra exploded view) designed for the Boreal Filter D400 with Valve (WF000015). It provides a secure, leak-free threaded connection between the filter’s multiport valve and the pool pipework, and includes the necessary O-ring seal for a watertight joint. Replacing a worn or damaged union set restores the integrity of your filter circuit quickly and reliably.

Compatibilità

This union set is designed specifically for the AstralPool Boreal Filter D400 with Valve, parent SKU WF000015, covering filter diameters Ø400, Ø520, and Ø640 mm. It corresponds to position 8 in the official Fluidra/AstralPool exploded parts diagram. Always verify your filter’s model number before ordering to ensure correct fitment — a separate 2″ union set (R0598300) exists for larger Boreal models (Ø760 and Ø900).

Perché l'originale conta

Genuine AstralPool parts are manufactured to the exact tolerances of the original equipment, ensuring the union threads mate perfectly with the valve body and the O-ring seats properly to prevent leaks. Third-party unions may vary in thread pitch or material quality, risking drips, pressure loss, or damage to the valve inlet. Using an original part also keeps your filter installation compliant with manufacturer specifications.

Installazione

The union set is designed for straightforward hand-tight installation — no thread tape is required on the union connection, as the included O-ring provides the seal. Ensure the O-ring is correctly seated before threading the union onto the valve port. If you are unsure about your plumbing configuration, a qualified pool technician should carry out or supervise the installation.
