This thread adapter converts 1.5" NPT thread to 1.25" BSP for holding tank and fuel sender installations

The thread adapter - SHS to S3H - is a crucial component for retrofitting an S3-H or S3 sender into a tank that previously had a Wema SHS holding tank sender fitted. This adapter bridges the gap between older and newer tank sender systems, ensuring compatibility and ease of installation.

As Wema SHS senders have been discontinued, this adapter provides a seamless solution for upgrading to modern 1.25" BSP senders while utilizing existing 1.5" NPT threaded holes. This versatility makes it an essential tool for boat owners and marine technicians looking to update their tank monitoring systems without the need for extensive modifications.

Crafted from 100% brass, this thread adapter offers exceptional durability and corrosion resistance, making it ideal for marine environments. The included nitrile o-ring ensures a watertight seal, preventing leaks and maintaining the integrity of your holding tank or fuel system.

This thread adapter is an indispensable solution for boat owners looking to upgrade their tank monitoring systems while maintaining the use of existing tank openings. It simplifies the installation process and ensures compatibility between older tanks and modern sender units, making it a valuable addition to any marine maintenance toolkit.
