Shell Naturelle S4 Stern Tube Fluid 100

Shell Naturelle S4 Stern Tube Fluid 100 is a non-emulsifying synthetic fluid specifically developed for use in stern tubes. Manufactured from fully saturated esters, Shell Naturelle S4 Stern Tube Fluid 100 is designed to offer superior lubrication performance while also being readily biodegradable ａnd having low ecotoxicity.

Designed to offer superior lubrication performance

Fully saturated esters ensure excellent resistance to oxidation ａnd hydrolysis while offering high-temperature thermal stability.

Excellent hydrolytic stability

A non-emulsifying fluid with excellent water separation ａnd anti-foaming characteristics that helps to maintain equipment performance.

Environmentally considerate

• EU Eco Labelled
• Independently certified as VGP compliant

Increased wear protection

Ashless (zinc-free) additives provide protection over a wide range of conditions.

Shell Naturelle Fluid HF-E 46 ａnd 68

Cutting Operating Costs

Hydraulic fluids that fail to protect your equipment from wear ａnd corrosion can increase maintenance costs ａnd reduce equipment availability. Shell Naturelle HF-E helps to lower maintenance costs by offering excellent wear protection over a wide temperature range. The naturally high shear stable viscosity index (VI) of Shell Naturelle HF-E helps to deliver responsive performance from cold start to full-load, heavy-duty operation.

Shell Naturelle Fluid HF-E is blended from synthetic base stocks with a naturally high VI of 180–190. The absence of viscosity modifier additives means the fluid is shear stable (i.e., there is no loss of viscosity control under high shear operating conditions) ａnd offers multigrade performance with no loss of VI during use. The viscosity–temperature curve is much flatter than that of conventional hydraulic fluids.

Shell Naturelle S4 Gear Fluid 68, 100 ａnd 150

Prematurely worn components can mean additional maintenance costs ａnd reduced equipment availability. Shell Naturelle S4 Gear Fluid can help to lower maintenance costs by offering outstanding anti-wear ａnd load-carrying performance through their high-quality, synthetic ester base fluid ａnd advanced non-toxic anti-wear additives.

If water ａnd air contaminate your oil, its ability to reduce friction ａnd keep your gears working efficiently may be compromised. Shell Naturelle S4 Gear Fluids help to cut operating costs by maintaining system efficiency through their excellent water separating, load-carrying ａnd anti-wear characteristics.

Shell Naturelle S4 Gear Fluid meets industry standard DIN 51517/3 CLP-E, including full water separation in less than 30 minutes according to DIN ISO 6614.

Longer Service Life

Fully saturated esters ensure excellent resistance to oxidation ａnd hydrolysis while offering high-temperature thermal stability. Shell Naturelle S4 Gear Fluid offers the potential to extend oil service life compared with conventional mineral gear oils.

Load Carrying ａnd Wear Protection 

Shell Naturelle S4 Gear Fluid is formulated to have excellent loadcarrying capacity ａnd anti-scuffing performance. Advanced non-toxic additives provide protection over a wide range of conditions ａnd ensure long component life, even under shock-loading conditions. All Shell Naturelle S4 Gear Fluid grades pass the FZG load test above load stage 13 according to ISO 14635 A20.
