Diana 30071600 Piston Seal
Description
Description
The Diana 30071600 is an original manufacturer replacement piston seal designed for a wide range of Diana spring-powered air rifles. The piston seal is the critical wear component that forms a compression-tight fit between the piston head and the cylinder bore — its condition directly determines the power output, consistency, and efficiency of any spring-piston airgun.
Measuring 28 mm in diameter, this seal is compatible with the majority of Diana's large-frame spring-piston platform spanning several decades of production, including the Diana 34, 48, 52, 54 Airking, 60, 66, 75, 280 Classic, 300R, 340 N-TEC, 460 Magnum, and related models. When performance has declined — indicated by reduced velocity, inconsistent shots, or audible loss of compression — a piston seal replacement is typically the first and most effective maintenance step.
As a genuine Diana OEM part (part number 30071600), this seal is manufactured to the exact tolerances specified for the original production rifles, ensuring a correct fit without modification. It is suitable for owners and gunsmiths carrying out routine maintenance, overhaul, and restoration work on Diana spring-piston airguns.
