Silicone Seals & Gaskets,
Standard Dies, Custom Sections
Solid and foam silicone sealing strips, cords and custom profiles — D-shape, O-shape, P-shape, E-shape and beyond. Most standard sections run on existing dies with no tooling cost, and every profile can be delivered cut-to-length or with adhesive backing.
Product Overview
Sealing Strips That Start From Your Gap
Good sealing is geometry plus material. YUTIAN covers both: a deep library of standard cross-section dies — so most profiles need no tooling — and solid or foam silicone formulations tuned to your compression, temperature and environment.
With over 1,141 seals and gaskets part numbers produced over the past decade, chances are your section already has a die.

Manufacturing & Quality
From Compound to Qualified Product
Three coordinated bases — raw material, functional compounds and precision extrusion — under one quality system.
Quality Control at Each Stage
- Incoming material inspection — compound properties verified before production
- Cross-section dimensional checks — profile geometry verified during extrusion
- Adhesive bonding quality — backing adhesion checked before shipment
- Final inspection & traceability — batch records from compound to shipment
Monthly averages: ≥ 95% self-inspection pass rate, ≥ 99% customer acceptance rate. In-house laboratory covering GC-MS, tensile, burst, thermal aging and UV weathering tests.
