KUS Welding Mounting Adapter / Weld-On Flange with 1 1/4" BSP Female Thread - Stainless Steel

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 precision-cut 1 1/4" BSP internal 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 of the NS3H series directly into the tank in a matter of seconds and with absolutely no leaks.

Advantages & Technical Highlights at a Glance:

• Highest material quality: Depending on the variant, manufactured from high-purity, saltwater- and fuel-resistant stainless steel (V4A) or seawater-resistant marine aluminum.
• Ingenious screw-in system: Enables extremely quick 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 transmitters or the digital high-tech KUS NMEA 2000 holding tank transmitter, model NS3H, with protective cage.
