Our Services
Here at Silflex, we’re proud of the complete end-to-end service we provide for silicone hose design, development, and production. From sourcing specialist components to manufacturing to tight tolerances, from the engineering of complex assemblies to validating performance in our in-house test facility – we control every stage to ensure quality, reliability, and compliance.
Component Sourcing
High-performance hose systems rely on more than just a high-quality silicone. Fittings, inserts, reinforcement materials, clamps, and specialist liners all play a critical role in ensuring mechanical integrity, chemical compatibility, and overall endurance.
Silflex manages the sourcing of every component used within our hose assemblies, working with trusted suppliers and certified manufacturers to guarantee reliability and full material traceability.
What Silflex provides:
- The procurement of high-quality hose inserts, fittings, and connectors
- Sourcing of specialist materials including FKM/Viton Profuel Liner, Silgiene®, and fire-retardant silicones
- Controlled supply chain with full traceability
- Materials selected for temperature, pressure, chemical, and regulatory requirements
- Support for OEM-specific or application-specific component standards
Our sourcing processes ensure that every hose assembly is built from materials engineered for the highest level of performance.
Hose Design
Our Hose Design Capabilities
- Custom shapes, bends, reducers, elbows, and multi-branch configurations
- Design for tight routing paths and confined spaces
- Pressure-rated and vacuum-rated constructions
- Specification of reinforcement materials (polyester, Nomex®, wire helix, etc.)
- Integration of specialist liners: Silgiene® and FKM/Viton Profuel
- CAD-based design and dimensional modelling
- Support with prototype development and validation
From high-temperature turbocharger hoses to sterile pharmaceutical tubing, our design team ensures your solution is engineered precisely for its environment.
Hose Insert Design
Standard inserts readily available on the market often fail to meet the requirements of our customers applications. Silflex creates custom inserts which perfectly match the silicone hose assemblies to enhance system durability, improve fluid flow and enhance the overall system performance.
Capabilities Include
- Custom metal, composite, or polymer insert design
- Smooth-bore, stepped, or profiled insert geometries
- Corrosion-resistant materials for marine and industrial environments
- Fuel- and oil-resistant designs for automotive, truck, bus, and off-highway applications
- Optimised design for pressure retention and mechanical stability
- Perfect integration with bespoke hose shapes
- Development of inserts for prototype or volume production
By designing inserts specifically for each application, we reduce the risk of leaks, improve performance, and eliminate common failure points.
Hose Manufacturing
Silflex silicone hoses are manufactured using established processes, high-quality silicone materials, and precision tooling – ensuring consistent, repeatable performance across every production batch. Our manufacturing capabilities cover simple straight lengths through to complex assemblies with tight tolerances and specialist reinforcement.
Manufacturing Strengths
- Mandrel-built hoses in a wide range of sizes
- Multiple reinforcement options (polyester, Nomex®, wire helix, glass-fibre braid)
- One-piece assemblies to eliminate joint failures
- Multi-layer hose construction for high-temperature or high-pressure environments
- Controlled curing and finishing processes for consistent wall thickness
- Convoluted and castellated options for increased flexibility
- Rapid prototyping and short lead times for custom builds
- Scalable production for OEM volumes
Every hose is built for reliability in some of the world’s most demanding environments.
Hose Testing Lab
Performance, safety, and compliance are at the core of every Silflex product, and we have built a reputation for quality that we are enormously proud of. Our in-house testing service validates hose performance through rigorous mechanical, thermal, and pressure testing, ensuring each product meets the exact requirements of its application.
Our Testing Capabilities
- Pressure testing with full documentation
- Vacuum testing for negative-pressure systems
- Burst testing for safety margin verification
- Heat-ageing and thermal-cycling tests
- Chemical compatibility testing
- Dimensional inspection and tolerance validation
- Material testing for hardness, elongation, and tensile strength
- Traceability, certification, and compliance reporting
Whether you require testing for internal quality assurance, third-party certification, or industry compliance, our lab provides the data and documentation needed for complete confidence.
Tooling Manufacturing
Precision tooling is the basis of every high-performance silicone hose we make. All our tooling is designed and manufactured in-house, giving us total control over accuracy, consistency, and quality of production. This capability enables us to create highly complex hose geometries that fit perfectly within confined engine bays, industrial systems, and specialised equipment.
Our tooling processes support straight lengths, elbows, reducers, multi-branch assemblies, convoluted hoses, and fully bespoke shapes engineered to match exact installation paths. By rapidly developing the tooling and with strict dimensional control, we ensure that every hose starts with precision and ends with guaranteed performance.
Our Tooling Capabilities
- CAD-designed mandrels and tooling for consistent geometry
- Rapid prototype tooling for fast development cycles
- Tight-radius and complex multi-plane shapes
- Tooling solutions for multi-layer and high-temperature constructions
- Controlled tolerances for repeatable, high-volume manufacturing
- Cost-effective tooling options for OEM production
By manufacturing our own tooling, we eliminate uncertainty, shorten lead times, and ensure every hose is built to the highest standards of accuracy and reliability.
Specialist Range
