What is the difference between Genuine VW and these?
Performance and material wise, they are identical.
The only difference is the molding technique.
Genuine and OEM seals are made from long extrusions of this rubber in the profile the seal needs to be, then cut to the desired thickness.
This is why the ends have a matte texture, while the sides are smooth.
These seals are compression molded, which uses a full mold of the exact seal shape. The elastomer is inserted into the mold and then the other side is brought into contact with the other half, compressing it Then the rubber is vulcanized and goes through a deflashing process to remove extremely thin “material” that oozes out between the two halves of the molds. This results in uniform finish on all sides of the part.
Then the rubber seals is cured, inspected, and packaged and shipped.
Practically there is no functional difference for this application, since it doesn’t need incredible tolerances.
But compression molding has better tolerances overall, particularly in Z. So that’s kind of cool.
Who is making them? How can the quality be trusted?
These seals were reverse-engineered and manufactured by NIYOK SEAL in Taiwan to OE material and tolerance specs.
I chose this company to produce the intake seals because I have worked with them since 2022 and their quality is superb. All our HNBR o-rings have come from them.
The specific Viton compound was developed from performance and environmental test on the genuine seals, from European manufacturer Solvay/Syensqo
All seals go through AOI dimensional check, with material report on each production run.
SUSTDI guarantees 100% perfect fitment and exact OEM performance with these seals.
INCLUDES SHIPPING.
