Pelengas Polyurethane Piston (13 mm Barrel, Mares Jet, Omer, Beuchat, Tigullio / Cressi, Asso)

The polyurethane piston 13 mm by Pelengas is a patented solution designed for optimal performance in underwater hunting. It fits barrels with a 13 mm diameter and is compatible with popular speargun models, including Mares Jet, Omer, Beuchat, and Tigullio OR Cressi, Asso.

Made from high-strength polyurethane using hot casting technology, this piston resists deformation, shock, and compression. The embedded hardened sear catch and a single sealing O-ring ensure smooth and reliable operation. A standout feature is the oil metering effect, which automatically lubricates the barrel as the piston moves, enhancing performance and extending lifespan, especially in saltwater use.

This polyurethane piston for 13 mm not only maintains consistent pressure but also minimises internal wear thanks to its gentle contact with the barrel walls.
