<h6>More info</h6>
<p><strong>Producer: Airsoft parts</strong><br /> The piston head is made of a structural plastic TECAFORM also known as <strong>POM</strong> on the CNC machine. Nine holes are drilled on the front side.The air stream flows through these holes during compression thus expanding the O-ring which provides for better sealing of the space between the piston head and the cylinder.</p>
<p>The centre of the piston head is passed through by the lock nut, which spreads the clamping force over a larger area and therefore prevents breakage of the bolt from the body of the piston head.</p>
<p>This piston head also incorporates an <strong>axial ball bearing</strong>.</p>
<p><strong>!! NBU piston</strong> <strong>head</strong> has modified dimensions. For this reason, it is only possible to combine with the <strong>NBU cylinder</strong>.<strong> !!</strong></p>
<p><strong>Advantages:</strong></p>
<ul>
<li>High resistance</li>
<li>Perfect sealing plus  guide rings</li>
<li>Axial ball bearing for easy spring rotation</li>
<li>Plastic nut that reduces total weight</li>
</ul>
