Bosta – O-ring 75 × 5.3 mm for Counter Current System Type STP

This is a genuine Bosta replacement O-ring measuring 75 × 5.3 mm, designed as a spare part for the Bosta Counter Current System Type STP. It provides a pressure-tight seal at critical joints within the system, preventing leaks and maintaining reliable water-tight performance during operation.

Compatibilità

This O-ring is a factory spare part for the Bosta Counter Current System Type STP range, which uses 75 mm pipe connections. Always cross-reference your system’s part number before ordering to confirm fitment, as counter current systems are available in multiple sizes and variants (including STP-SS models).

Perché l'originale conta

Genuine Bosta sealing components are manufactured to exact tolerances for the STP system’s housings and connection points. An incorrectly sized or substandard O-ring can lead to water ingress, pressure loss, or accelerated wear — making like-for-like replacement with an authentic part the safest and most cost-effective choice.

Installazione

Replace the O-ring whenever signs of leakage, deformation, or cracking appear at sealed joints. Ensure mating surfaces are clean and free of debris before fitting. For systems installed in pool walls or with complex pipework, professional installation is recommended to avoid disruption to the counter current unit.
