Blue Silicone Hose in Straight Lengths (Imperial & Metric)

Description

Automotive Silicone Hose
Our modern and highly flexible manufacturing process allows our production facility to cope with a wide range of products and a diverse customer base. We produce specialist one off prototypes, low volume parts and high volume production for the bus, truck and automotive markets. Having our own dedicated factory means we can focus on specific requirements and tailor our production to the ever changing needs of our customers.

General

Good physical and chemical compatibility with coolant and corrosion inhibitors.
For conveyance of oil and fuel, a fluorosilicone liner is required (see our FSH product line).
Standard colour is blue but other colours are available upon request.
All hoses to meet or exceed SAE J20R1 class A.

Production and Technical Options
We offer part number 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: Megaflex recommend and can provide a range of clips, ideal for all hose clamping solutions. See our fittings section for more details.

Construction
We manufacture silicone hoses to the highest standard designed to operate under the most extreme conditions found anywhere in today’s modern engines. Our silicone hoses are manufactured using high quality silicone from world leading suppliers. The woven and knitted polyester fabric reinforcement used is of the highest quality and supplied by leading UK manufacturers.

Our standard range of hoses are constructed using 3 4 or 5 plies of fabric depending on diameter with a minimum wall thickness of 4.5mm. Other construction options are provided according to service conditions and specific customer requirements. Our materials and specifications are carefully chosen to provide a hose which offer easy fitting combined with maximum performance.

A range of sprung stainless steel wire or nylon cord reinforced silicone hoses are also offered. These can be used in applications where a great deal of flexibility is required high working pressures up to 30 bar are experienced or high vacuum or suction is applied. Our range of wire reinforced hoses can be supplied as a smooth uniform hose or with a spiral convoluted or castellated form providing much greater flexibility. These hoses can be used in any vehicle systems industrial applications wind turbines and any high or low pressure systems.

Custom Designed and Bespoke Hoses
We 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. We also offer a design service for non-standard applications providing full technical and 3D drawings for approval and future reference.

Applications
Our silicone hoses are specifically designed for use in coolant systems on trucks buses passenger cars generators railway engines and many other vehicle and industrial applications where connections are required between rigid or flexible metal pipes. They are ideal for joining pipes of similar or differing diameters – reducers. Available in standard sizes from 6mm to 152mm diameter with diameters greater than 152mm made to specific customer requirements. Our automotive silicone hoses meet or exceed the requirements of SAE J20 R1 Class A."
