Gas Struts 700mm

Dunn & Watson 700mm Gas Strut – Engineered for Endurance in Harsh Conditions

The Dunn & Watson 700mm Gas Strut is a high-performance component designed to provide reliable support and smooth operation in challenging environments. Ideal for applications such as camper trailers, caravans, 4WDs, toolboxes, and canopies, this gas strut ensures durability and consistent performance.

Key Features

• Stroke Length: 310mm

• Fully Extended Length: 700mm

• Cylinder Diameter: 22mm

• Shaft Diameter: 10mm

• Thread Size: M8

• End Fittings: Compatible with 13mm ball joints

Advanced Engineering for Superior Performance

• Advanced Skeleton Oil Seal Design: Features a premium L-shaped “Skeleton Oil Seal” that delivers superior sealing performance with reinforced structural integrity. This design resists deformation, protects against contaminants, and ensures minimal gas leakage even under high pressure and frequent use.

• Purity That Protects: Filled with 99.9999% pure nitrogen, these struts avoid the internal corrosion and degradation caused by oxygen or moisture in lower-purity fills—ensuring consistent performance and a significantly longer service life.

• Nitrocarburised Rods for Maximum Durability: Every strut features a nitrocarburised rod, offering far greater corrosion and wear resistance than standard chrome. This surface treatment prevents rust, reduces seal wear, and is ideal for marine, off-road, or industrial use—where cheaper struts often fail prematurely.

• More Oil. Bigger Cylinder. Longer Life: With more oil and a larger cylinder than the industry average, Dunn & Watson struts deliver smoother operation, better heat dissipation, and extended performance across their lifespan.

Available Force Ratings

The 700mm gas strut is available in multiple force ratings to suit different load requirements:

• 100N: Suitable for lightweight applications

• 200N: Designed for moderate loads

• 300N: Ideal for heavier loads

• 400N: For demanding applications requiring substantial support

• 500N: Suitable for heavier applications

• 600N: Designed for demanding loads

• 700N: For substantial support requirements

• 800N: For very heavy applications

• 900N: Suitable for extremely heavy loads

• 1000N: Designed for maximum support

• 1100N: For ultra-heavy applications

• 1200N: Maximum force rating for the most demanding applications

Note: The force rating is measured in Newtons (N), and the appropriate rating should be selected based on the weight and application requirements.

Durability and Testing

Dunn & Watson gas struts undergo rigorous testing to ensure reliability:

• Cycle Testing: Each strut is tested to 50,000 cycles to simulate long-term use.

• Corrosion Resistance: The shafts are subjected to 150 hours of salt exposure testing to assess corrosion resistance.

• Backup Seals: Manufactured with additional backup seals to ensure continued operation in the unlikely event of a primary seal failure.

Applications

This gas strut is versatile and can be utilized in various settings, including:

• Automotive: Assisting in the smooth operation of hatches, tailgates, and bonnets.

• Recreational Vehicles: Facilitating easy access to storage compartments and canopies.

• Industrial Equipment: Supporting lids, doors, and panels for efficient operation.

• Marine: Enhancing the functionality of boat compartments and storage areas.

Installation and Compatibility

The 700mm gas strut is designed for easy installation and is compatible with standard mounting brackets and fittings. It is essential to select the appropriate force rating based on the weight and application requirements to ensure optimal performance.
