No, this hose is designed specifically for air and coolant and is not compatible with fuel or oil contact.
The inner bore diameter for this specific model is 25mm.
No, fixings and clamps are not included; you will need to source 25mm-compatible clamps separately.
You can trim the leg lengths using a very sharp utility knife or a fine-tooth blade, ensuring the cut is straight for a proper seal.
4-ply refers to the four layers of reinforcing fabric embedded within the silicone, which significantly increases the pressure rating and durability.
Ensure the pipe ends are cleaned with degreaser and use a high-quality T-bolt clamp for a more even distribution of clamping force.
Verify that the hose bend is not forced into a radius tighter than its design allows, which can cause wall deformation.
Immediately replace the hose if it feels soft or mushy, as this usually indicates contact with incompatible fluids like oil or fuel.
To install, ensure the mating surfaces of your pipes are clean and free of debris. Slide the hose onto the pipe ends and secure them with appropriate worm-gear or T-bolt clamps (not included). Avoid over-tightening clamps, as this may damage the silicone layers. While the silicone is resistant to coolant and air, it is essential to keep the hose clear of fuel or oil mist, as these chemicals will degrade the material over time. Regular inspections are recommended to ensure clamps remain secure and the hose shows no signs of external abrasion.
