Weihrauch HW97/ HW77 Lightweight Piston - 26mm


Weihrauch HW97/ HW77 Lightweight Piston - 26mm

This genuine factory piston which we modify will improve your Weihrauch springer 'lock time' thanks to less moving mass. This should aid in repeatable accuracy as well as reduced recoil.

This item is compatible with the following air rifles:
- Weihrauch HW97

- Weihrauch HW77

- Possibly other rifles in the HW range, ordered at customers' own risk.

This Lightweight piston is a direct replacement for the standard Weihrauch 26mm piston.

Please measure the diameter of your piston before purchasing as some early Weihrauch spring rifles run a 25mm piston, not 26mm!

Piston seal upgrade
This item is supplied with a standard piston seal but this can be swap for a upgraded piston seal.

Standard seal - The OEM seal that your spring rifle leaves the factory with.

Eco seal - This is a uprated version of the factory seal, designed to give you better sealing on the compression stroke as well as being harder wearing than the standard seal.

Red seal - This is a special design, CNC made piston seal. Made from high quality Molybdenum disulphide impregnated Polyurethane, permanently lubricated and rated to 1000 bar. This offers even better sealing than the ECO and standard seal as well as being even harder wearing due to the design and material it has been made from.

Both the Eco seal and Red seal are made and supplied by Custom Air Seals Australia.
