MwSt. **Verfügbarkeit:** Auf Lager **Artikelnummer:** 33107 **Marke:** KUS **Kategorie:** KUS Instruments ## Beschreibung #### **KUS Weld-On Mounting Adapter / Weld-On Flange with 1 1/4" BSP Female Thread – For Custom Metal Tanks** Build or modify your custom metal boat tank to a truly professional standard! The original **KUS welded mounting adapter (weld-on flange) with threads** is the perfect solution for shipyards, welders, and discerning DIY boat builders. The solid metal ring features a precisely cut **1 1/4" BSP female thread**. It is welded directly over the tank cutout and forms an extremely stable, warp-free, and permanently leak-proof base for your screw-in fuel level sensor. Forget about drilling screw holes or tedious counterboring inside the tank—this weld-on ring allows you to screw the precise KUS S3 dip-tube transmitters or the modern, digital NMEA 2000 transmitters from the NS3H series directly into the tank in a matter of seconds, with absolutely no leaks. --- #### ⚠️ **Important note on material selection (welded joint):** To guarantee an absolutely secure, material-compatible, and durable weld, the adapter’s material must match that of your tank. Please select the appropriate option from the dropdown menu above: - **Stainless steel version (AISI 316 / V4A):** For welding onto stainless steel tanks. - **Marine aluminum version:** For direct welding onto aluminum tanks. --- #### **Advantages & Technical Highlights at a Glance:** - **Highest material quality:** Depending on the version, manufactured from high-purity, saltwater- and fuel-resistant stainless steel (V4A) or seawater-resistant marine aluminum. - **Ingenious screw-in system:** Enables extremely fast sensor installation and removal (e.g., for cleaning purposes) without additional mounting screws. - **Precise thread:** Clean 1 1/4" BSP (British Standard Pipe) internal thread—compatible with all standard marine threaded sensors. - **Universal use:** Ideally suited for all types of custom-built metal tanks (gasoline, diesel, fresh water, gray water, and holding tanks). --- #### 🛠 Installation tip from Tenten-Boats: Complete your tank installation! Combine the threaded weld-on flange directly with the durable analog **KUS S3 screw-in sensors** or the digital high-tech **KUS NMEA 2000 holding tank sensor model NS3H** with protective cage. --- #### **Technical Data (Specifications):** **Property** **Specification / Value** **Manufacturer / Brand** KUS **Product Type** Weld-On Flange / Weld-On Adapter for Threaded Tank Sensors **Thread Specification** 1 1/4" BSP female thread (British Standard Pipe) **Material Options** V4A stainless steel (AISI 316) or seawater-resistant marine aluminum (depending on selection) **Compatibility** KUS S3 (analog) & KUS NS3H (digital NMEA 2000) ## Varianten ### Version - aluminium — Art.-Nr. 33107-A - stainless steel — Art.-Nr. 33107-B ## Bilder - https://tenten-boats.de/media/image/product/81884/lg/kus-schweiss-montageadapter-anschweissflansch-mit-1-1-4-bsp-innengewinde.jpg --- Kanonische Seite: https://tenten-boats.de/KUS-Weld-On-Mounting-Adapter-Weld-On-Flange-with-1-1-4-BSP-Female-Thread Strukturierte Daten (JSON-LD): https://tenten-boats.de/KUS-Weld-On-Mounting-Adapter-Weld-On-Flange-with-1-1-4-BSP-Female-Thread.json
