About Us

Custom Plastic Gaskets for Your Application

Flexiparts produces a wide range of plastic gaskets from durable materials, CNC-machined or molded according to customer specifications. We handle various types and materials for sealing, insulation, vibration control, and chemical resistance.

Design Plastic Gasket Suggestion

When specifying a plastic gasket, consider sealing surface conditions, compression, operational temperature, and chemical exposure. Define key dimensions such as thickness, inner and outer diameter, and groove fitment, and select materials based on pressure, environment, and insulation needs. Adding features like ribs or lips can improve sealing and assembly, while consistent wall thickness ensures reliable production quality.
