Silicone Turbo-charger (charge air cooler) Hoses
Manufactured from only the highest quality silicones and reinforcement fabrics, LHSS silicone hoses are designed to operate at temperatures from -50°C up to +250°C and at operating pressures up to 6 bar. Bespoke hoses can be manufactured to withstand significantly higher pressures where required.
Our silicone hoses offer superior reliability even when operating under the extreme conditions found on modern Euro 6 engines. Our air intake hoses can be manufactured to withstand the low, negative pressures experienced on many modern engine systems, while maintaining good flexibility. Our Turbo-charger and intake hoses are used by many OE vehicle manufacturers in Euro 5 and Euro 6 applications.
Our multi-directional test rig allows Leyland Hose & Silicone to prove our Turbo-charger (CAC) and intake hoses, under severe conditions at up to 230°C.
LHSS silicone hoses are specifically designed for use in the turbo-charger and intake systems on trucks, buses, passenger cars, generators, railway engines and many other vehicle and industrial applications where either rigid or flexible connections where either rigid or flexible connections with high, multi-directional movement are required.
Leyland Hose and silicone produce a wide range of straight sleeves, shaped non-convoluted hoses and convoluted hoses (bellows). Convoluted hoses are produced with both conventional cuffed ends or, with V-band connections.
V-band clamp hoses are particularly useful where space limitations restrict fitting of the hose. They are ideal for joining pipes of similar or differing diameters – reducers, turbo chargers, intercoolers and air intake systems.
LHSS manufacture charge air cooler hoses for both hot and cold-side applications. See under construction section for more details.
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 silicone and UK sourced fabrics, 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.
Fuel and Oil Resistance
Where fuel or oil mist is present, normal silicone material will absorb and degrade rapidly during service. Leyland Hose & Silicone offer 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
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.
Material Specification – Silicone Compound

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.
Straight sleeves up to 152mm diameter as standard, shaped hoses, straight convoluted hoses – with or without stainless steel rings, elbows, elbows with convolutions – with or without stainless steel rings, reducer elbows and straights.
Produced in a variety of complex shapes, with or without convolutions for added flexibility. Leyland Hose & Silicone produce intake hoses with multi outlets. Air sensors can be built into the hose wall. Wire reinforced hoses for high vacuum resistance are also produced.
Leyland Hose and Silicone manufacture silicone hoses to the highest standard, designed to operate under the most extreme conditions found anywhere in today’s modern engines. LHSS silicone hoses 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 offer 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.
Production and Technical Options
- Part making 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.
Custom Designed and Bespoke Hoses
LHSS have ‘in-house’ tool manufacturing capability. In addition, we have the support of local and other tool manufacturers.
This allows us to offer a wide range of product options, from simple elbow hoses to complex shapes, bellows and large intake hoses. Leyland Hose and Silicone also offers a design service for non-standard applications, providing full technical and 3D drawings for approval and future reference.
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 silicone hose, out-performing many other hoses offered on the market today.
Benefits of Silicone Turbo-Charger Hose
Ideal for where engine movement may be severe
The inherent heat and flame resistance helps improve the safety, performance and durability
Higher flexibility than convectional materials such as EPDM
Hoses perform over a much wider temperature range (-50ºC to +250ºC)
