Product Code: Yellow-Piston Cup 3"
Phenolic Fabric Piston Cup is a high-strength hemispherical piston support component for high-pressure plunger pumps, molded from fabric-reinforced phenolic resin with woven texture reinforcement. It provides axial support and radial guidance, bears heavy radial loads, stabilizes piston movement, prevents shaft eccentricity and abrasion, and protects sealing components. It features ultra-high pressure resistance, excellent wear resistance, self-lubricating and dimensional stability. Available in Yellow (Premium Grade, Higher Price) with high-density fabric for heavy-duty equipment, and Black (Standard Grade) for general plunger pumps, ideal for ultra-high pressure plunger pumps, water jet equipment and industrial cleaning machinery.
