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.

SectionsD-shape, O-shape (cord), P-shape, E-shape, hollow, rectangular and custom
MaterialsSolid Shore A 30–80; foam Shore C 25–85 — per sealing load
Delivery FormContinuous coils, cut-to-length, spliced rings, adhesive-backed

With over 1,141 seals and gaskets part numbers produced over the past decade, chances are your section already has a die.

Technical FAQ

Questions Engineers Ask First

My section is non-standard. What does tooling really cost?
Non-standard cross-sections require a new die; tooling cost and lead time are quoted individually based on your drawing and volume — there is no flat fee. Share the section drawing and target quantity for a specific quotation.
Can you supply gaskets ready for my assembly line?
Yes — cut-to-length, spliced rings and adhesive-backed strips are standard finishing options, so your line gets parts that fit the assembly step directly.
Can you make custom / non-standard profiles? Is tooling required?
Yes. Most extruded profiles (D-shape, O-shape, solid, hollow, custom sections) can be produced with our existing dies. Non-standard cross-sections require a new die; tooling cost and lead time are quoted individually based on your drawing and volume — there is no flat fee.
Can you cut to length? Do you offer bonding?
Yes, we cut to your required length; special cutting and splicing/bonding are available. Whether cutting is charged depends on the process and quantity.
What colors are available?
Standard colors include black, white, transparent, red, blue and grey. We can color-match to a RAL number or your sample. Special colors may affect price — quoted per order.
What is the MOQ? Do you sell short lengths?
Free samples are available for stock products. After sample approval, order MOQ is typically 500–1,000 meters depending on the product (confirmed in the quote). For the sample stage, even a few meters can be arranged.
Are samples free? How fast can you provide them?
Stock samples are free of charge; shipping is paid by the customer. Custom sample tooling is evaluated by process. Sampling typically takes 3–7 days.
