Copper Press Fittings for VRF Systems | EN12541 & ASME B16.22

Copper Press Fittings For VRF System play a central role in modern variable refrigerant flow (VRF) and VRV air conditioning installations. Unlike traditional brazed joints, press fittings use a mechanical crimp that compresses the copper tube and fitting together, creating a hermetic seal without flame, flux, or filler metal. This method reduces fire risk, avoids oxidation inside the pipe, and preserves refrigerant cleanliness, which is critical for compressor reliability and energy efficiency in VRF systems. As a Zhejiang-based manufacturer with a global outlook and more than 19 years of development, we produce Copper Press Fittings For VRF System using high-precision machining and rigorous inspection. Our principal range includes End Feed Fittings, Press Fittings, Solder Ring Fittings, and ACR Fittings, all widely applied in plumbing pipe connection systems, air conditioning and refrigeration connection systems, gas systems, and medical piping systems. For international contractors and distributors, this means consistent quality that meets EN12541, ASME B16.22, and AS 3688 standards, simplifying specification and approval across markets. Installation efficiency is a major benefit. A single press tool completes each joint in seconds, allowing faster commissioning of large VRF networks and reducing dependence on highly skilled brazing labor. The flame-free process also protects heat-sensitive components and insulation, which is important in retrofit and occupied-building projects. Additionally, copper’s natural corrosion resistance and compatibility with common refrigerants extend system life and reduce maintenance costs. Choosing the right fittings requires attention to tube size, wall thickness, sealing O-ring material, and press tool compatibility. Our Copper Press Fittings For VRF System are engineered for dimensional accuracy and stable sealing performance across temperature and pressure cycles. With a customer-focused approach, we continue optimizing our product portfolio and quality to support efficient, eco-friendly refrigeration and HVAC piping worldwide.
