HW57 Piston Seal

The Weihrauch HW 57 piston seal 9076 is a precision replacement part designed to restore the compression and performance of your Weihrauch HW 57 air rifle. A worn piston seal is one of the most common causes of reduced power and inconsistent shooting performance, often together with a weakened mainspring.

When replacing the piston seal, it is important to thoroughly clean the compression cylinder and ensure that the inside of the cylinder tube is free from oil, grease, and dirt before installation. A clean cylinder helps the new seal bed in correctly and contributes to reliable long-term performance.

Manufactured to precise specifications, this HW 57 piston seal provides an accurate fit, excellent sealing properties, and long service life. It is the ideal replacement for routine maintenance, repairs, or restoring your Weihrauch HW 57 to its original performance.
