GORE® Automotive Vents – PPAP: An Overview

United States

PPAP (Production Part Approval Process) is integral to the ISO/TS 16949 Quality System.

It defines generic requirements for production part approval. It ensures that parts manufacturers, like Gore, document our capability to consistently meet your product specifications when manufacturing that product at quoted production levels.


There are different PPAP Levels, each with different types of documentation. As you might expect, Level 1 involves the least amount of documentation. But a higher number does not always mean more documentation. As shown below, Level 3 actually requires the most documentation.

You choose the Level that meets your needs. Whether you choose Level 1, 2, 3, or 4, Gore has streamlined the process to eliminate complexity and confusion — so you get your completed PPAP documents promptly and accurately!

When Is a PPAP Needed?

  • When a customer is purchasing a GORE® Automotive Vent for the first time. (This includes current customers who begin purchasing parts from a different manufacturing facility.)
  • When a customer or Gore has made any change that affects the form, fit, or function of the GORE® Automotive Vent.
  • When a customer requests it. Customers may request a PPAP for reasons such as annual recertification or a change in engineering drawings.

When a PPAP is needed, Gore is not permitted to ship parts to the customer until customer has signed and returned the Parts Submission Warrant form, which signals completion of the PPAP approval process.

Are There Exceptions?

Yes, a customer may sign a waiver so that product can be shipped before PPAP Approval is complete. There are two types of waivers:

  • Waiver of PPAP just for the first shipment. This allows an order to be processed and the first shipment to be sent out, even though the PPAP Approval process is not yet completed.
  • Waiver that attests that no PPAP is needed. Therefore, Gore is free to process your initial & all future orders and ship product without delay.

Your Gore representative can help you establish a waiver, if you require one.
