0558009550 - ESAB PT-36 Nozzle Retaining Cup XR

Genuine ESAB Protection for PT-36 Torches

The ESAB Nozzle Retaining Cup XR (Part Number: 0558009550) is a critical component designed specifically for the high-performance PT-36 plasma cutting torch. In the demanding world of industrial plasma cutting, the integrity of your torch's front-end consumables dictates the quality of the cut and the longevity of the equipment. This retaining cup acts as the primary housing that secures the nozzle, swirl ring, and electrode in perfect concentric alignment, ensuring the plasma arc remains stable and focused.

Manufactured in the United States to ESAB's rigorous OEM standards, the XR series retaining cup is built to withstand the intense radiant heat and back-spatter associated with heavy-duty automated cutting. Unlike generic aftermarket replacements, this genuine ESAB part guarantees the correct thread pitch and thermal expansion properties required for the PT-36 system. Using non-OEM parts in high-amperage torches can lead to gas leaks, arcing faults, and even catastrophic torch head failure. By choosing the 0558009550, you are investing in the reliability and safety of your cutting operations.

Optimized Gas Flow and Durability

Beyond simply holding parts in place, the Nozzle Retaining Cup XR plays a vital role in gas dynamics. It helps channel the shielding gas around the arc, cooling the nozzle and protecting the cut zone from atmospheric contamination. Its robust physical dimensions (approximately 4.15 x 4.25 x 4.7 inches packaged) reflect a heavy-duty design capable of enduring the mechanical stresses of industrial environments. Regular inspection of the retaining cup is recommended; if you notice cracks, thread damage, or excessive burn marks, immediate replacement is necessary to maintain cut quality and prevent damage to the torch body.

Whether you are running a high-volume fabrication shop or a specialized manufacturing line, keeping your PT-36 torch outfitted with fresh, genuine consumables like the ESAB Nozzle Retaining Cup XR is essential for minimizing downtime and maximizing productivity.
