Silicone Valves & Membranes Medical Grade

Silicone Valves & Membranes

Duckbill, umbrella and slit valves with precisely tuned crack pressures — molded for repeatability at volume.

MOQ: Per project — pilot volumes welcome Customizable

Key Features

  • Crack pressure tuned to your spec window, verified per cavity
  • Stable across high-cycle fatigue testing
  • Rapid prototype tooling for valve geometry iterations

Product Description

One-way valves and membranes where opening pressure is the whole product. We mold duckbill, umbrella, cross-slit and custom geometries, tuning durometer and geometry until crack pressure sits inside your specified window — then hold it across millions of cycles. Typical applications include drainage, dispensing, respiratory interfaces and diagnostic consumables.
