Hello! Welcome to the official website of Xinxiang Xingda Filter Co., Ltd.!
Product Overview
The Center Tube, also known as the Core Tube or Inner Skeleton, is the critical structural backbone of any high-quality filter element. Designed to withstand high differential pressures and extreme flow conditions, our center tubes ensure the mechanical integrity of the filter assembly. Whether for automotive, industrial, or hydraulic applications, a robust center tube prevents filter collapse and guarantees consistent filtration performance.
Superior Structural Integrity: Engineered to support the filter media (pleats) effectively, preventing deformation under high pressure differentials.
Optimized Flow Design: Precision-engineered perforation patterns (round holes, slotted, or spiral) maximize the open area, reducing flow resistance and pressure drop.
Corrosion Resistance: Available in various materials including galvanized steel, stainless steel (304/316L), and engineering plastics to suit aggressive fluid environments.
Versatile End Configurations: Customizable end caps, threads, and sealing surfaces ensure a perfect fit for various filter housings.
