Milwaukee 49-16-2414 1/2” ProPEX Expander Heads w/ RAPID SEAL Our Milwaukee 49-16-2414 1/2” ProPEX Expander Heads w/ RAPID SEAL are precision engineered for accurate expansions and auto-rotating compatibility. Milwaukee designed the RAPID SEAL™ expansion head segments to deliver you up to 65% faster sealing of connections as temperatures decrease, ultimately providing the fastest times to begin a pressure test.

Made from high strength steel, the chrome-plated segments, and black oxide ring combine durability and weather resistance. Optimized for use with M12 FUEL™ ProPEX® Expander, heads are compatible with Milwaukee® M12™ and M18™ Expanders except for the M18™ FORCE LOGIC™ ProPEX® Expansion Tool. Size markings on the ring and collar surface provide you with easy recognition at any orientation.
