Pharmaceutical-Grade Pressure-Resistant Silicone Tubing & Crimped Tubing

Customized solutions for high-pressure fluid transmission

In biopharmaceutical manufacturing, fluid transfer occurs under harsh conditions such as high pressure, high flow rates, vacuum, and repeated CIP/SIP cycles—demanding piping with exceptional pressure resistance and longer service life.
LePure Biotech’s pharmaceutical-grade pressure-resistant silicone hose series delivers outstanding pressure resistance, flexibility, and resistance to aging. Constructed as a composite of high-purity medical-grade silicone and a high-strength reinforcement layer, it is manufactured via precision extrusion with enhanced process. Custom integrated crimped assemblies are available in a full range of sizes, ideal for high-pressure fluid transfer and long-term circulation applications.
The entire series complies with GMP, USP Class VI, and ISO 10993 biosafety standards, delivering safe, stable, and traceable quality assurance for high-pressure fluid transfer in biopharmaceutical process.
