Gas Strut Replacement Finder

Identify matching Trailer Parts Direct gas struts from the specifications of the gas strut you are replacing. This tool is for like-for-like replacement identification only.

Replacement identification only. This finder does not calculate, design or specify gas struts for new installations and must not be used to increase or decrease the Newton rating of an existing installation.

1. Are you replacing an existing gas strut, or selecting gas struts for a new installation?

2. What Newton rating is printed on your existing gas strut?

Look for a sticker, etched or printed number on the strut body, usually shown as 100N, 300N, 500N or similar. Enter the same rating as the strut being replaced.

3. What is the fully extended length from centre of eye to centre of eye?

Measure the existing strut fully extended from the centre of one mounting point to the centre of the mounting point at the opposite end.

4. What is the compressed length?

Optional. If already known, enter the centre-to-centre compressed length. Do not remove or manually compress a strut merely to obtain this measurement.

5. What diameter is the strut shaft / gas cylinder?

This identifies the existing product series. The finder will prefer this series when equally close, but may show a different series if it is the closest same-Newton replacement within 50mm.

6. What end fitting is fitted to your existing gas strut?

7. Installation Environment

Protected examples include inside a toolbox, 4WD canopy, caravan tunnel boot or another primary structure preventing constant exposure. Exposed applications may use standard steel, but 316 stainless is recommended. Marine or other corrosive environments return 316 stainless steel only.

Before ordering: independently confirm the Newton rating, extended length, compressed length where available, shaft/cylinder size, material and end fittings against the existing gas strut. If the specifications do not match, do not assume a similar-looking strut is suitable.

I confirm that I am replacing an existing gas strut and have checked the specifications entered against the strut being removed. I understand this finder identifies matching catalogue products and does not design or certify my installation.

Gas Strut Safety - Read Before Removal or Installation

Always independently support the lid, hatch, door or panel before removing or installing a gas strut. Never work beneath a panel supported only by gas struts.
Gas struts contain pressurised gas and stored energy. Do not drill, puncture, cut, crush, weld, open or deliberately damage a pressurised gas strut. Follow the manufacturer's disposal instructions.
Do not expose gas struts to excessive heat, flame or conditions outside the manufacturer's specified operating limits.
Do not install or reuse a strut that is bent, dented, badly corroded, leaking, mechanically modified or otherwise damaged.
Avoid scratching, painting, greasing, contaminating or damaging the piston rod.
Do not subject the strut to side-loading, bending or misalignment. Existing mounting points and fittings must allow the strut to move freely without binding.
Do not exceed the intended stroke or use the strut as a mechanical end stop unless the original application was designed that way.
Keep hands and body parts clear of hinges, brackets, pinch points and moving panels during removal and installation.
If the existing specifications cannot be positively identified, the replacement does not match, or you are unsure about safe removal or installation, stop and seek professional assistance.

When installing gas struts in marine or outdoor applications, choosing the right material is essential. The Dunn & Watson 150mm Stainless Steel Gas Strut is manufactured from high-quality 316 stainless steel to provide enhanced protection against corrosion while delivering dependable support for compact lids and access panels.

Ideal for Marine and Outdoor Use

Whether fitted to a boat storage hatch, caravan access door, camper trailer compartment or 4WD toolbox, the 316 stainless steel construction makes this strut particularly suited to locations exposed to humidity, moisture and coastal conditions.

Its compact design provides a practical solution where longer gas struts cannot be accommodated.

Engineered for Long-Term Performance

Dunn & Watson stainless steel gas springs incorporate an advanced L-shaped skeleton oil seal designed to minimise nitrogen leakage and maintain consistent pressure.

The high-purity nitrogen filling, combined with generous internal lubrication, helps deliver reliable extension and controlled movement through repeated use.

Multiple Force Ratings Available

Choose from force ratings between 50N and 200N to suit your installation requirements. Whether replacing a worn gas strut or installing a new lift support, the 150mm 316 stainless steel gas spring delivers quality construction in a space-saving design.
