Put an end to the leaking of those otherwise good pistols. Will also fit Daisy 780/790. The kit includes high performance oil-resistant o-rings including a transfer port seal which helps to stop the blow-off and waste of CO2 bypassing the transfer port, resulting in higher velocity! (The original design does not have any seal.)

Installation is easy, pin punch required. Comes with instructions, but give it to a gunsmith if you feel uncomfortable. Note: some of our our o-ring dimensions are different from the originals to compensate for the poorly engineered groove dimensions. Guns fitted with our seals hold pressure much longer.

Make sure you order for the correct caliber as seal dimensions differ.

When ordering a seal kit, optionally add a spare o-ring for the piercing body; as it is frequently exposed, it may get damaged by dirt or wears out sooner.

 Replacement piston (part #62; Kolben) for Walther LP2 and LP3 out of stock

After half a century, the piston seals of nearly all Walther LP2 and Walther LP3 are decaying, due to low quality mineral oils or the inferior Ballistol used as a chamber lube. Nowadays, much better products, like synthetic oils, are readily available.

Simply install this new design with our two oil-resistant o-rings. Guns fitted with this piston usually shoot 350fps.

2 replacement seals and installing instructions are provided.
