Our product has 200,000 times piston durability testing .

The central shaft is made of all-copper material ,with high-quality surface treatment, which perform much better ,without deformation or oxidation.

Our products development and production under the engineers from.

Shell material using Americn which is more sturdy and durable.

We use American imports Dupont nylon PA66-GF30, not easy to deform.
The valve cage cushion uses imported ACM material ,-30 -150 degree temperature resistance, the screw hole position error less than 2mm and convenient for installation.
Flatness error with cylinder head less than 3mm, better sealing performance.

Our raw material from Dupont , same as OE product ,Using FVMQ and HNBR as core raw material .
Better material used for the seal in comparison with original product.Will still restore after being deformed by 3times.
We have well-made molds.Installation dimension tolerance less than 0.2mm.
The filter purchased from the same factory as MANN.

Our product with more scientific internal structure to ensure the service life.
