Φ55 Quartz Tube Fitting (Internal Core Type)

This product is a Φ55 quartz tube connector (with an internal core), manufactured from high-purity quartz and featuring a precision internal-core design. It is compatible with Φ55 quartz tubes and is used for precise alignment and connection in quartz tubing systems, gas-line transmission, or sealed transitions. As a quartz vacuum/ambient-pressure tubing connection component, it offers excellent light transmittance, corrosion resistance, and reliable sealing performance.

Key features:
1. Core-embedded design for precise alignment: The precision core-embedded design enables accurate positioning and tight coupling of the Φ55 quartz tube, ensuring no loosening or misalignment after installation. This guarantees smooth gas flow and prevents medium leakage.
2. Compatible with Φ55 specifications and highly versatile: Specifically designed for Φ55 quartz tubes, it is compatible with all standard Φ55 quartz tubing systems and can be directly connected to quartz tubes, valves, fittings, and other components of the same specification—no additional adapters required, ensuring broad compatibility.
3. High-purity quartz material with outstanding performance: Utilizing high-transmittance, high-purity quartz, this material boasts exceptional light transmittance and is free from impurity interference. It also exhibits excellent resistance to high temperatures and corrosion, making it suitable for a wide range of complex media and high-temperature applications.
4. Reliable sealing and versatile applicability: Featuring a dedicated sealing design, this product delivers outstanding sealing performance, making it suitable for a wide range of operating conditions, including vacuum and atmospheric pressure, with an extremely low leak rate to ensure stable operation of the piping system.
5. Smooth inner wall for excellent flow conductance: The quartz material features a smooth, burr-free inner surface with no dead corners, resulting in high fluid conductance, minimal dust accumulation, easy cleaning and maintenance, and prevention of residual contamination.
6. Robust Structure and Easy Installation: The overall structural design is rational, with excellent rigidity that resists breakage and deformation, and the installation process is straightforward, enabling rapid connection and secure fixation of quartz tubing.
