How we use information

We use collected information to respond to product inquiries, provide seal material and structure recommendations, prepare quotations, support sample confirmation, process orders, arrange delivery, provide after-sales service, improve website content and protect website security.

For industrial applications such as vacuum pumps, air compressors, fluid equipment, mixers, pumps, valves, food and pharmaceutical equipment, semiconductor tools and precision industrial systems, submitted parameters help us evaluate suitable PTFE, FFKM, elastomer, spring and metal sealing solutions.

Inquiry forms, operating conditions and drawings

Forms on this website may request contact details, product requirements, equipment names, operating parameters, media information, drawings, photos, existing model numbers or other seal-selection data.

These materials are used only for product selection, technical communication, quotation confirmation, sample development, order execution, quality traceability and customer service. We do not sell, rent or illegally provide your personal information, drawings, operating-condition data or commercial requirements to third parties.

If drawings, sample photos or technical files involve confidentiality requirements, please tell us when submitting them. We will take reasonable confidentiality measures and limit access to internal technical, sales, quality and production personnel who need the information for business purposes.

If comments are enabled, we may collect data shown in the comment form, visitor IP address and browser user agent to help detect spam and protect the website. If you upload images, drawings or other files, please note that files may contain hidden metadata such as EXIF GPS location, device information or author information. You should remove any information you do not wish to transmit before uploading.
