Weihrauch Piston Seal 9069 for HW35, HW80 and HW90. Precision replacement seal for optimum compression and consistent performance.
The Weihrauch Piston Seal 9069 is a precision replacement piston seal designed to restore the compression and performance of your Weihrauch HW35, HW80, or HW90 air rifle. A worn piston seal is one of the most common causes of reduced power, inconsistent velocity, and poor shot-to-shot performance. Replacing the seal restores proper compression and helps your rifle perform as intended.
Before installing the new piston seal, make sure the compression cylinder is thoroughly cleaned and completely free from oil, grease, and dirt. A clean cylinder ensures the seal can bed in correctly, providing maximum compression and a long service life.
For older HW35 rifles originally fitted with a leather piston seal, an additional piston seal adapter (8622) is required to install this modern synthetic seal.
Compatible with:
Manufactured to original specifications, the 9069 piston seal provides an accurate fit, excellent sealing performance, and outstanding durability, making it the ideal replacement for maintenance, repairs, or a complete air rifle overhaul.
