What does II. quality mean?
Products in the second quality category are 100% functional, but they may have a minor defect that does not affect the functionality of the product itself. Each product is inspected and only then released for sale.
All defects are individually mentioned for each product.
The products of the second quality category also come with a 2-year warranty.
The PolarStar R107 Solenoid Valve is a critical component used in all generations of the Fusion Engine – from the original GEN1 to the latest production models. This is a genuine, purpose-built valve designed specifically for PolarStar systems, offering higher performance and longer lifespan compared to standard off-the-shelf options.
Equipped with 4.7-watt coils, the R107 delivers faster response times and more precise operation during firing. It also features a tighter internal seal, significantly reducing air leaks and enhancing overall system reliability, even under heavy use.
If you're serious about maximizing the potential of your PolarStar HPA setup, the R107 is a must-have upgrade. It is fully compatible with all Fusion Engine generations and is the go-to choice for players demanding top-tier performance and durability.
