LHSS have produced a new type of silicone hose, specifically designed and formulated for use on Fuel Cell and Hybrid vehicles such as Auto Silicone Hoses. Our FCSH range of hoses are lined with a technically advanced, clear silicone which has been developed to minimise the risk of contamination to fluid or air carried by the hose.
Conventional silicone can contain trace level extractable materials which, can be a slight risk to fuel cell and hybrid systems. LHSS – FCSH hoses offer all of the service benefits expected from normal silicone hoses, such as high temperature resistance and low temperature flexibility.
FCSH hoses are suitable for use in a wide range of chemical fluid/gas transfer applications where the risk of contamination needs to be minimised. Auto Silicone Hoses are also ideal for applications such as, motorsport, bus, truck, rail and static generator applications.
Leyland Hose & Silicone Turbo-charger and Inter-cooler hoses, offer the highest degree of reliability under extreme under bonnet applications. Manufactured from only the highest quality components, hoses are offered from the design stage to your complete solution for turbo and inter-cooler applications. Our constructions are thoroughly tested and proven at temperatures up to 230°C on our multi-directional test rig, giving our customers confidence in the performance and reliability of Leyland Hose & Silicone CAC hoses.
Where fuel or oil mist is present, normal silicone material will absorb and degrade rapidly during service. LHSS offers superior, fluorosilicone lined hoses, to resist fuel, oil and diesel. Using the highest quality fluorosilicone material as a liner, our unique manufacturing process enables us to achieve an inter ply bond strength of almost double that found when tested against several competitor hoses. LHSS use only 100% fluorosilicone. However, we remain competitive due to our efficient manufacturing process, where many competitors use ‘diluted’ fluorosilicone material in order to reduce cost.
Part marking including specific customer logo, part numbers and traceability options.
High temperature reflective sleeving, providing protection in specific vulnerable areas for example, close to turbo or exhaust systems.
Anti-abrasion sleeving. This can provide protection where a hose is likely to come in to contact with moving or, vibrating components.
Hose Clamps: Leyland Hose & Silicone recommend and can provide a range of clips, ideal for all hose clamping solutions.
Our dedicated factory is equipped with an extensive range of test equipment which allows LHSS to monitor, maintain and provide materials and product to both customer and our own unique and demanding specifications.
All product used in our hose building process, is supplied with customer certification. We carry out our own in-house testing to verify batch to batch consistency.
In addition, LHSS are able to carry out product testing. Our factory has the facilities to carry out burst pressure testing, heat ageing, vibration and flex testing and pressure cycle testing.
At Leyland Hose and Silicone, our priority is to ensure we can offer our customers a consistent and high quality Auto silicone hose, out-performing many other hoses offered on the market today.
LHSS manufacture silicone hoses to the highest standard, designed to operate under the most extreme conditions found anywhere in today's modern engines. They are manufactured using high quality silicone from world-leading suppliers. The woven and knitted meta-aramid fabric reinforcement used, is of the highest quality, supplied by leading UK manufacturers.
Our standard range of hoses are made using 3, 4 or 5 plies of fabric depending on diameter, with wall thickness and construction dependent on service conditions and flexibility required. Our materials and specification are carefully chosen, to provide a hose which offers easy fitting combined with maximum performance.
Where a high vacuum resistance is required, for example on off highway or most modern Euro 6 standard engines, hoses can be constructed with either a wire helix built within the wall or, with internal, stainless steel springs.
Polyester – For ‘Cold-side’ hoses or, hoses where service temperature does not exceed 180°C.
Weight: 190gsm +/ - 17gsm
Burst pressure: 16Bar (232 psi)
Tensile strength: 75-80 Kgf Temperature range: -50°C up to 180°C
Woven or Knitted Meta-aramid – For ‘Hot-side’ hoses or where service temperatures reach 230°C.
Temperature range: -50°C up to 230°C.
Woven meta-aramid gives higher stiffness and burst pressure when required. Specialist manufacturing techniques allow us to impart higher strength with good flexibility in both radial and axial directions when building convoluted turbo-charger hoses.
