Because H-Seals are manufacutured on CNC lathes, custom configurations are often no more expensive than standard H-Seals. We are happy to provide quotations for short run as well as high-volume production orders.

Prototype, First Article & Short Runs

Once your custom configuration has been designed and you are ready to order prototypes or a short run for testing, we will provide you with a quotation for 10, 20, 50 or 100 pieces. Lead times very but are generally 4 - 10 weeks.
