V-Mach Pistol Seal 16J for Weihrauch HW85 | HW95 | HW98
PS-HW85/95/98-12
New
Premium Part: V-MACH Piston Seal
Piston seals help airguns keep stable air compression, which improves velocity consistency and accuracy. With less friction inside the chamber, the piston moves more smoothly and transfers energy more efficiently.
For competitive shooters, this means tighter shot groups, reduced vibration, and more predictable performance over long sessions. Modern polymer seals also last longer, keeping the rifle performing at its peak.
This is a custom piston seal for the Weihrauch HW50S, HW57 and HW99S models tailored for the best shooters.

More info
Piston seals in airguns play a crucial role in maintaining consistent air compression, which directly affects velocity stability and shot-to-shot precision.
Premium custom piston seal, from the V-MACH tuning house for the Weihrauch HW50S, HW57 and HW99S models, for those expecting the best performance and the best results.
A high‑quality seal reduces friction inside the compression chamber, allowing smoother piston movement and more efficient energy transfer.
For top shooters, this translates into tighter velocity spreads, improved pellet flight consistency, and better control over long‑range accuracy. Modern seals made from advanced polymers also resist wear, keeping performance stable over many thousands of shots.
Upgrading to a premium piston seal can therefore elevate an airgun’s overall feel, reduce vibration, and deliver the kind of repeatability that competitive shooters rely on to stay at the top of their game.
Compatibility:
- Weihrauch HW50S
- Weihrauch HW57
- Weihrauch HW99S
