45 Degree Silicone Hose for Air and Piping Systems
A 45 degree silicone hose is used to connect pipes or fittings at an angle. The preformed 45 degree bend provides a gradual change of direction and is ideal for pipework that cannot be routed in a completely straight line. QSP Products supplies 45 degree silicone elbows in various internal diameters, with blue and black available as standard colours.
45° silicone hoses can be used in air, intercooler and compatible coolant systems. They are widely used in automotive and motorsport applications as well as machine building, industrial equipment and other technical installations.
When should you use a 45 degree silicone hose?
A 45 degree silicone elbow is suitable when two connections are not positioned directly in line and the pipework needs to make a gradual change in direction. The angle is less severe than a 90 degree bend and therefore provides different routing possibilities.
This can be useful when pipework needs to pass around an engine component, bodywork, machinery or another obstruction. By combining different pipes and silicone elbows, the system can be adapted to the available installation space.
45 degree silicone hose for air and intercooler systems
When constructing air intake, turbo and intercooler systems, aluminium pipes are not always positioned in a straight line. A 45 degree silicone hose can connect two pipe sections while providing the required directional change.
The preformed shape avoids the need to force a straight silicone hose into an unsuitable bend and helps the hose maintain its intended geometry.
45 degree silicone hose for coolant systems
A 45 degree silicone hose can also be used in compatible cooling systems. Typical applications include connections between aluminium coolant pipes and components positioned at an angle to each other.
QSP silicone hose has an operating temperature range from -60°C to +180°C and provides resistance to hot and cold water. Compatibility should always be checked when using specific coolant formulations.
VMQ silicone with polyester reinforcement
QSP silicone hose is manufactured from Silicone VMQ (Vinyl Methyl) with polyester reinforcement layers. Depending on the specification, wall thickness ranges from 4 to 5 mm. The hoses contain a minimum of three layers, while larger diameters can have four or more layers.
This reinforced construction combines the flexibility and permanent elasticity of silicone with additional dimensional stability for a wide range of technical applications.
Working pressure of 45 degree silicone hose
The permitted working pressure of QSP silicone hose depends on its internal diameter. Smaller and larger diameters therefore do not necessarily have the same pressure rating.
For pressurised systems, always check the technical specifications of the individual hose size and use the product within its specified operating limits.
Which size 45 degree silicone hose do I need?
QSP silicone hose dimensions are specified according to the internal diameter (I.D.). QSP aluminium pipes are specified according to their outside diameter (O.D.), making it straightforward to match both components.
For example, a 51 mm O.D. aluminium pipe requires a silicone connection with a 51 mm I.D. If you are unsure of the required size, measure the outside diameter of the pipe or fitting before selecting the hose.
Combine 45 degree silicone elbows with aluminium pipes
45 degree silicone elbows can be combined with aluminium pipework to create custom piping systems. Straight aluminium tubes can form the longer sections, while silicone elbows provide the required changes in direction.
QSP Products also supplies aluminium tubes, aluminium bends, connectors, reducers and hose clamps, allowing different components to be combined into a complete system.
Why use a preformed 45 degree silicone elbow?
Although straight silicone hose is flexible, forcing it into a significant bend is not always desirable. Excessive bending can create unnecessary mechanical stress or affect the shape of the hose.
A preformed 45 degree silicone hose already incorporates the required angle, allowing the pipework to change direction without forcing a straight hose into position.
Installing a 45 degree silicone hose
Slide both ends of the silicone elbow sufficiently over the pipes or fittings and secure each connection with at least one suitable hose clamp.
Install the hose without unnecessary pulling or twisting forces. Avoid contact with sharp edges, moving components and extremely hot parts.
Resistance to ageing, moisture, ozone and UV
QSP silicone hose is resistant to ageing and moisture and offers very good weather-resistant properties. The material remains permanently elastic and also provides resistance to ozone and UV.
These properties make 45 degree silicone elbows suitable for a variety of technical environments involving changing temperatures and environmental conditions.
45 degree silicone elbows for automotive and motorsport
45 degree silicone elbows are widely used for custom pipework in automotive and motorsport applications. Typical examples include race cars, rally cars, off-road vehicles, kit cars and modified road cars with custom air, intercooler or coolant systems.
Different hose shapes and diameters allow pipework to be routed around engines and other vehicle components according to the available space.
Suitable for industry and machine building
A 45 degree silicone hose is not limited to vehicle applications. Silicone elbows can also be used in machine building, industrial installations, agricultural machinery and other technical systems where pipework needs to change direction.
The combination of flexibility, temperature resistance and resistance to ageing makes silicone suitable for a wide range of technical environments.
Chemical resistance of silicone hose
QSP silicone hose provides resistance to hot and cold water, hot air, ozone, UV and diluted acids and bases. Compatibility should always be verified for specific chemical applications.
Standard silicone has limited applicability with oils, lubricants, greases, OAT antifreeze and coolants based on organic acids. Where additional resistance to these fluids or fuels is required, a suitable oil-resistant hose should be selected.
45, 90, 135 or 180 degree silicone hose?
The correct silicone elbow depends mainly on the position of the connections and the required pipe route. A 45 degree elbow provides a relatively gradual directional change, while a 90 degree elbow is designed for right-angle connections. 135 and 180 degree hoses can be used where more significant directional changes or return connections are required.
Combining different elbows with straight silicone hose and aluminium pipework makes it possible to create a custom piping system.
Complete range of silicone hose connections
In addition to 45 degree silicone elbows, QSP Products supplies straight silicone hose, 90 degree, 135 degree and 180 degree elbows, silicone couplers, reducers, T-pieces, bellows and vacuum hoses.
QSP Products keeps approximately 18,000 silicone hoses in stock in a wide variety of shapes and diameters. Blue and black are the standard colours, allowing many commonly used configurations to be supplied directly from stock.
