Hook set for O-ring and gasket removal, Rockforce RF-903G13, 3-piece

The Rockforce RF-903G13 hook set is a three-piece tool kit designed for safe and precise removal of O-rings and gaskets from grooves, housings and confined spaces. Each hook has a different shape and reach to access seals in a variety of positions while minimizing the risk of scratching or deforming adjacent components. The set is intended for workshop, automotive and maintenance environments where controlled seal extraction is required.

Advantages

The set provides targeted access to seals thanks to three distinct hook profiles that fit common O-ring and gasket geometries. Hardened tips and ergonomic handles improve control during extraction, reducing slippage and the chance of damage to mating surfaces. Lightweight and compact, the tools are easy to carry in a toolbox or on a service cart and allow technicians to remove seals quickly without relying on improvised tools.

Suitable for

• Removing O-rings from engine and hydraulic component grooves
• Extracting gaskets from housings and assemblies in confined spaces
• Workshop maintenance and routine service tasks requiring seal replacement
• Automotive repairs, mechanical servicing and light industrial maintenance

Key specifications

• Set composition: three hook shapes with varying bend angles and lengths
• Tip material: hardened steel for wear resistance
• Handle: ergonomically shaped for improved grip and control
• Finish: corrosion-resistant coating on metal parts
• Dimensions: compact sizes suitable for tight access areas

How to use

Select the hook shape that best reaches the seal without putting pressure on surrounding surfaces. Position the tip under the O-ring or gasket edge and apply steady, controlled leverage to lift the seal out of its groove. Work slowly around the circumference for circular seals, and use a different hook if access or angle changes. Inspect the seal seating area for damage and clean the groove before installing a new seal.

Usage recommendations

Use appropriate personal protective equipment and ensure components are secured before attempting extraction. Avoid excessive force that could damage sealing surfaces; if a seal is seized, apply a suitable penetrating lubricant and allow time to work before levering. Store the hooks in a protective pouch to maintain tip condition.
