Fluke TL175 TwistGuard™ Test Leads

The Fluke TL175 TwistGuard™ Test Leads are engineered with user safety and versatility in mind, making them an essential accessory for reliable electrical measurements. Their patented TwistGuard™ technology allows you to adjust the exposed probe length—from 19 mm for traditional testing to just 4 mm for maximum safety—ensuring compliance with modern electrical safety standards. The correct category rating (CAT II 1000 V, CAT III 1000 V, CAT IV 600 V) is always visible based on the selected tip exposure, giving technicians confidence that they are testing within safe limits.

In addition to adjustable tip length, the TL175 leads include Fluke’s WearGuard™ insulation, a dual-layer silicone jacket that signals when the leads are worn and need replacement. The outer black layer reveals a white inner layer upon damage, providing a clear visual cue for safety. Built for demanding environments, the silicone insulation remains flexible in cold conditions, resists high temperatures, and is paired with heavy-duty strain relief tested to withstand over 30,000 bends.

Designed for compatibility and convenience, the TL175 test leads use universal input plugs that work with any instrument accepting standard 4 mm shrouded banana connectors. Whether you’re working in CAT II, CAT III, or CAT IV-rated environments, these test leads deliver both peace of mind and long-lasting performance, all backed by Fluke’s reputation for safety and reliability.
