M3251 Description

Short technical summary and product information.

The Heyco M3251 is a Flex Liquid Tight Cordgrip designed for panel mounting with 1/2 NPT threads. It provides reliable strain relief and sealing for cables, wires, and tubing in demanding environments.

 

This cordgrip accepts cables with diameters from 0.170 to 0.450 inches (4.32 to 11.43 mm). The housing is made of Nylon 6/6 (PA66) with a Buna N or TPE sealing gland, offering resistance to salt water, weak acids, gasoline, alcohol, oil, grease, and common solvents. It features an integral sealing ring for a tight seal at the mounting panel without requiring an O-ring.

 

The M3251 is rated IP68, making it dust tight and waterproof. It operates at temperatures from -40°C to 115°C static and -20°C to 100°C dynamic. The flammability rating is UL 94V-2. Locknuts are not included. The flexible pigtail extender prevents sharp bends and extends cable life.
