RUKO Soldering Tip Extension DIN 377, 2.1 mm

This RUKO extension bridges the gap between your soldering iron and hard-to-reach joints, adding 45 mm of reach without changing your tip's behaviour. It threads directly onto Weller WSP 80, WP 80, MPR 80, FE 75 and LR 21 irons, then accepts any 2.1 mm shaft tip on the other end.

Highlights

• Extends reach by 45 mm for precision work in confined spaces
• Compatible with Weller WSP 80, WP 80, MPR 80, FE 75, LR 21 irons and 2.1 mm tips
• High-grade heat-resistant metal alloy for durability up to 450°C
• ESD safe for sensitive electronics
• Screw-on installation, no tools required

In daily use

The extension transfers heat efficiently, so your tip reaches full working temperature without a noticeable drop. The metallic silver finish resists oxidation and solder splash, keeping maintenance low. Since it is a conductive part with no insulation, keep it clear of live circuits and grounded surfaces during use.
