430-027055 - Hypertherm Silicone O-Ring Lubricant 1/4 oz

Hypertherm 027055 Silicone Grease for Plasma Torch Maintenance

The Hypertherm 027055 Silicone Grease is an essential maintenance consumable designed to prolong the life and performance of your plasma cutting system. Supplied in a convenient 1/4 oz (7g) tube, this high-quality silicone lubricant is specifically formulated to withstand the high temperatures and demanding environment of plasma cutting operations. It is the recommended lubricant for all Hypertherm plasma torch O-rings, ensuring a proper seal and preventing damage during consumable changes.

Regular maintenance of your plasma torch is critical for consistent cut quality and system reliability. Dry or cracked O-rings can lead to gas leaks, pressure loss, and even internal arcing that can damage the torch head. By applying a thin film of this silicone grease to the O-rings on your torch body and consumable stack, you ensure smooth installation of parts and maintain the integrity of the gas seal. This small tube provides enough lubricant for numerous applications, making it a cost-effective solution for protecting your investment.

This grease is chemically inert and non-conductive, making it safe for use near electrical components within the torch assembly. Unlike petroleum-based lubricants which can cause rubber O-rings to swell or degrade, this silicone formula preserves the elasticity and shape of the seals. Whether you are operating a Powermax system or a heavy-duty industrial plasma cutter, keeping a tube of Hypertherm 027055 on hand is a best practice for any professional fabricator.
