A gas strut that will not hold a canopy door, toolbox lid or machinery guard safely is more than an inconvenience. It can interrupt work, damage equipment and create a lifting hazard. This Australian gas strut warranty guide explains what a two-year warranty is designed to protect, what to check before making a claim, and how correct selection and installation help avoid problems in the first place.
For replacement struts, warranty support starts with getting the specification right. A strut can look identical to the old unit yet be wrong in force, length, end fitting or orientation. That mismatch can cause poor operation and may be mistaken for a product fault.
What a gas strut warranty is intended to cover
A standard two-year warranty provides confidence that a gas strut is supplied free from manufacturing defects and will perform as intended when it is correctly selected, fitted and used within its rated application. At Gas Struts, this applies to the supplied product under the applicable warranty terms.
A manufacturing fault may show up as a strut that loses pressure unusually early, has a defective seal, leaks oil or gas, binds internally, or has an end fitting failure under normal use. The key question is whether the strut has failed because of a defect in the product, rather than because it has been overloaded, incorrectly installed or exposed to conditions outside its intended use.
Gas struts are sealed, pressurised components. They are not generally repairable in the field. If a genuine defect is confirmed, the practical remedy is normally replacement of the affected strut, subject to the warranty terms and assessment of the application.
The Australia gas strut warranty guide: start with fitment
The most useful warranty check is often done before the strut is fitted. Record the details of the original part and compare them with the replacement specification. This protects the buyer and gives the supplier the information needed to identify a mismatch quickly.
Check the extended length from centre of end fitting to centre of end fitting, the compressed length, the rod diameter and cylinder diameter, and the type of end fittings at each end. The force rating, usually marked in Newtons as N, matters just as much. A 400N strut and a 700N strut may share similar physical dimensions, but they will behave very differently on a lid or hatch.
Also consider how the item is used. A caravan boot door, ute canopy, marine hatch and industrial access panel may all need a similar-looking strut, but the load, mounting geometry, opening angle and environmental exposure are different. If the panel has been modified, fitted with extra accessories or changed from its original design, the previous force rating may no longer be suitable.
For a pair of struts, replace both where practical. One new strut combined with one weak, aged strut can leave the load unevenly supported. It also makes it harder to diagnose whether the remaining issue is with the part or the application.
Conditions that can affect a warranty assessment
Warranty is not a substitute for appropriate installation and care. Gas struts have defined travel, force and mounting requirements. Forcing a strut beyond its closed or open length can damage internal seals or end connections. Using a higher-force unit to compensate for poor mounting geometry can overload hinges, brackets and the item being lifted.
The rod should be protected from damage. Scratches, dents, paint overspray, welding residue and corrosive contamination can damage the seal as the rod moves through it. In outdoor, marine, agricultural and mining environments, regular cleaning and application-appropriate materials are especially relevant.
Mounting orientation can matter too. Many gas struts are designed to operate rod-down when closed so internal lubrication supports seal performance. There are exceptions, particularly in specialised applications, so follow the specification provided for the strut rather than relying on a general rule alone.
Normal wear, accidental damage, corrosion caused by unsuitable exposure, modification, misuse and damage from incorrect installation may not be treated as manufacturing defects. The applicable product warranty terms determine each case. If there is any doubt before installation, ask for technical guidance rather than altering brackets or forcing a strut into position.
Check the whole lifting system before reporting a fault
A strut is often blamed when the real issue sits elsewhere in the assembly. Before removing the unit or lodging a warranty enquiry, inspect the hinges, pivots, brackets and lid alignment. A bent bracket, seized hinge or misaligned canopy door increases the force needed to operate the panel and can make a sound strut feel weak.
Look for a load change as well. Added spare wheels, drawer systems, solar panels, insulation, tools or aftermarket accessories can significantly alter the weight and balance of a hatch or lid. Cold weather can also make gas struts feel slower and less forceful temporarily. This is a normal characteristic of gas pressure, not necessarily a fault, although a strut that cannot support its load in ordinary operating conditions should be assessed.
If the strut is hard to compress by hand, that does not prove it is working correctly or incorrectly. Gas struts are designed to work through the geometry of the installed application. Testing them off the vehicle or equipment can be misleading and, with higher-force units, unsafe.
Information that speeds up a warranty claim
Clear information makes it easier to determine whether the issue is a product defect, an incorrect specification or an installation problem. Keep your proof of purchase and the product details where possible. A clear photograph of the printed part number or force marking is useful, along with images showing the strut fitted at both open and closed positions.
When contacting the supplier, describe the application and fault in practical terms. State whether the strut will not extend, will not hold the load, leaks, binds, has a damaged fitting or behaves differently from the matching strut. Include the number of struts fitted, their mounting points, and whether the problem began immediately after installation or developed over time.
For custom installations, provide the lid or panel weight, the distance between mounting points when open and closed, the intended opening angle, and photographs of the setup. These details may show that a revised force rating or mounting position is needed. That is not a failed warranty claim – it is a faster path to a safe working result.
Do not dispose of the strut before the assessment is complete unless instructed to do so. The supplier may need to inspect the component, verify the marking and assess the failure pattern. Avoid dismantling, drilling or modifying a suspect strut. Gas struts are pressurised and must be handled as supplied.
Installation practices that protect your coverage
Use the correct ball studs, brackets, pins or eye fittings for the strut and application. Secure retaining clips properly, but do not lever them off unnecessarily during removal. Support the lid, door or hatch independently before disconnecting a strut. Never rely on a single weakened strut to hold a heavy panel overhead.
Do not clamp the cylinder in a vice, grip the polished rod with pliers or apply heat near the unit. If an end fitting is threaded, use the intended fitting surfaces and avoid twisting the rod. After installation, cycle the application carefully several times and check that the strut reaches neither end of its travel before the lid or mechanism does.
For trade, fleet and maintenance teams, recording the part number, force rating, installation date and application in maintenance records is worthwhile. It supports planned replacement, helps identify repeated issues and makes any warranty enquiry much more straightforward.
A warranty is there for the uncommon event that a correctly selected and fitted gas strut has a genuine product fault. The better the application details and installation checks at the start, the faster the answer will be if something does not perform as expected – and the safer the equipment will remain in daily use.
