Silicone hoses and bellows - All types & sizes

Silicone hoses and bellows are used across fluid transfer, air intake and exhaust systems, vibration isolation, and expansion joint applications. In maritime contexts they can be specified where regulatory certification is required; Lloyd's Register-certified silicone hoses and bellows are available for marine installations. Selection depends on the medium being handled, temperature range, mechanical movement and required certification. For application-specific guidance and compatibility checks, you can contact our team for technical advice.

Silicone hoses provide elasticity, flexibility over a wide temperature range and resistance to ozone and UV exposure. They typically exhibit good electrical insulation properties and recovery from compression. Chemical compatibility varies by compound and reinforcement, and mechanical strength depends on reinforcement construction. For critical applications, confirm the specific silicone compound and reinforcement type against operational demands and relevant certifications such as Lloyd's Register where applicable. Our team can assist in interpreting material data for your requirements.

Selecting silicone hoses involves assessing operating temperature, system pressure, fluid or gas compatibility, required diameter, mechanical movement, and end‑connection type. Consider reinforcement layers, wall thickness and any regulatory or classification requirements relevant to the application, including maritime certification where applicable. For installations subject to vibration or cyclic motion, choose designs rated for flexing. If you need help matching product features to system parameters, contact our technical team for tailored advice.

Inspect silicone hoses regularly for surface cracking, hardening, softening, bulging, delamination, leaks or changes in flexibility. Maintenance typically involves cleaning with compatible, non‑aggressive detergents and avoiding solvents that may attack the compound. Replace hoses that show irreversible deterioration, leakage or mechanical damage, or that no longer meet functional or certification requirements. For maintenance schedules and end‑of‑life assessment specific to your operating conditions, consult our technical team for recommendations.
