Tuning FAC Firing valve seal gasket compatible with Hatsan BT65
These seals were manufactured
in Poland according to Serwis Wiatrowy's design.
By using a higher-grade material, we were able to modify the original design to achieve more efficient valve venting. This means our seal increases the muzzle velocity while maintaining the same hammer spring preload.
They distinguish themselves
from their original counterparts by their precision craftsmanship and
the use of significantly superior materials – high-quality, self-lubricating
polymers. The seals are often made from a material harder than the
original.
They are produced in small
batches to avoid so-called "stock aging,"
which ensures they maintain their optimal parameters, strength, and durability.
External diameter: 13mm.
The product is packaged in
transparent wrapping, allowing for inspection prior to installation.
