PC-305A - Broco PC-305A 3/8-Inch Collet and Washer Kit for PC/A-20 Torch

Broco PC-305A Collet and Washer for PC/A-20 Exothermic Torches

The Broco PC-305A Torch Collet and Washer assembly is a critical replacement component designed exclusively for the Broco PC/A-20 Prime Cut exothermic cutting torch. Engineered to withstand the rigorous demands of industrial cutting, demolition, and maintenance applications, this collet ensures your torch operates at peak efficiency. It is specifically sized to accommodate 3/8-inch diameter cutting rods, providing a secure mechanical hold and optimal electrical continuity required for arc ignition.

Manufactured from high-quality brass, the PC-305A is built to resist corrosion and endure the high-heat environments typical of exothermic cutting operations. One of the standout features of this component is its knurled outer surface. This texture provides a solid, non-slip grip, allowing operators to tighten or loosen the collet by hand, even while wearing heavy protective welding gloves. This design consideration is essential for minimizing downtime during rod changes in the field.

Debris and slag are common byproducts of the cutting process that can often jam standard threads. To combat this, Broco has engineered this collet with Acme threads. This specialized thread profile is robust and resistant to binding, ensuring that dirt, sand, or slag does not seize the nut, allowing for smooth operation over the lifespan of the part. The included washer serves a vital function by creating a tight seal within the torch head, preventing oxygen leakage which is crucial for both safety and the performance of the cutting stream.

Regular maintenance of your exothermic torch is vital for safety. A worn collet can lead to loose rods, poor electrical contact, or dangerous gas leaks. Replacing your old collet with the genuine Broco PC-305A ensures your equipment remains reliable, safe, and ready for the toughest cutting jobs.
