This genuine Bosta inlet\/outlet nut is an OEM replacement fastening component for the STP series counter-current swimming systems, covering the 2200, 3000, and 4000 models. It secures the water inlet and outlet pipe connections at the pump housing, ensuring a leak-free, pressure-tight seal under the high flow rates these systems generate. Keeping this nut in perfect condition is essential for reliable, safe operation of your counter-current jet.<\/p>\n
Designed exclusively for the Bosta STP Counter Current System in the 2200 W, 3000 W, and 4000 W variants (including both standard and SS stainless-steel editions). These systems use a 75 mm pipe connection and deliver flow rates up to 55\u201380 m\u00b3\/h, placing significant mechanical stress on all hydraulic fittings. Always verify your STP model before ordering.<\/p>\n
As a hydraulic fastener exposed to continuous water pressure and pool chemicals, an off-brand substitute risks thread mismatch, premature corrosion, or failure under load. This genuine Bosta part is manufactured to the exact tolerances of the original equipment, ensuring a perfect fit and long service life without the risk of costly water ingress or downtime.<\/p>\n
Replacement is straightforward for a qualified pool technician: isolate and depressurise the system, remove the old nut, fit the new one by hand and torque to specification. We recommend inspecting the mating threads and any associated gaskets or O-rings at the same time and replacing them if worn to achieve a fully watertight joint.<\/p>","protected":false},"excerpt":{"rendered":"
