PC/RP-305B - Broco PC/RP-305B 1/4" Collet and Washer Kit for Prime Cut Torch

Get Your Broco Torch Back in Action with the PC/RP-305B Collet Kit

If your Broco Prime Cut torch is sputtering, leaking oxygen, or just not gripping rods like it used to, it might be time to swap out the collet. The Broco PC/RP-305B 1/4" Collet Kit is the exact replacement you need to get back to slicing through steel, concrete, and cast iron without a hitch. This kit comes with everything required to refresh the front end of your torch setup for 1/4-inch rods: a durable brass collet and the essential sealing washer.

We know that out in the field, equipment takes a beating. Exothermic cutting generates intense heat, and eventually, even the toughest brass collets wear out. A loose collet causes arcing inside the head, which can ruin your torch body permanently. Don't risk your expensive equipment for the sake of a small part. Keeping a spare PC/RP-305B kit in your toolbox means you can perform a quick swap the moment you notice poor contact or a gas leak, minimizing downtime on the job site.

Installation is straightforward and restores the tight seal needed for efficient oxygen flow. The washer ensures that the oxygen goes exactly where it's supposed to—down the center of the burning rod—rather than leaking out the back. This maximizes the burn time of your rods and keeps the cut hot and fast. The brass collet is machined to bite into the rod securely, ensuring full amperage transfer for that instant ignition.

This kit is designed strictly for 1/4-inch rods. If you are switching between rod sizes, it is crucial to have the matching collet size installed to prevent accidents. Trust genuine Broco parts to keep your Prime Cut system running safely. Whether you are removing a seized pin on an excavator or cutting scrap, a fresh collet kit ensures your torch performs like new.
