4 mm külső átmérőjű pneumatikus tömlő, 7 m – STP ellenáramú rendszer – 7026756

Bosta – Pneumatic Hose 4 mm OD, 7 m – STP Counter-Current System (Part No. 25)

This is the genuine Bosta replacement pneumatic hose (Part No. 25) for the STP series counter-current system. With a 4 mm outer diameter and a pre-cut length of 7 metres, it connects the poolside pneumatic push-button to the system’s pneumatic switch, transmitting the air impulse that starts and stops the counter-current unit safely without any electrical connection at the pool wall.

Kompatibilitás

Designed specifically for the Bosta STP and STP-SS counter-current systems (e.g. STP-2200 and STP-2200SS). Always verify your unit’s parts diagram before ordering — this hose is listed as item No. 25 in the official STP exploded-view diagram.

Miért fontos az eredetiség?

The pneumatic circuit relies on an airtight, pressure-stable hose to deliver a clean signal to the pneumatic switch every time. A genuine Bosta hose is manufactured to the exact bore and wall-thickness tolerances required by the STP system, ensuring reliable triggering and long service life in the wet pool environment.

Telepítés

The 7 m length provides ample reach for most standard poolside installations, allowing the push-button to be positioned conveniently on the pool coping or deck. Route the hose through conduit or along the pool surround, cut to the required length, and push-fit onto the button and switch ports. No special tools are required, but professional installation is recommended to maintain warranty coverage.
