Precision Engineering for Reliable ConnectionsEvery union fitting is manufactured to DIN/ISO standards with a tolerance of 0.05 mm, ensuring compatibility and reliable sealing in critical plumbing and pneumatic systems. The brass construction, combined with a nickel-plated surface treatment, delivers high tensile and yield strength for robust performance.
Versatile Applications and Superior Corrosion ResistanceEngineered for use with water, air, or oil, this fitting is ideal for pipe coupling tasks in diverse environments. The nickel-plated brass material offers significant resistance to corrosion, making it suitable for both indoor and outdoor applications, even in challenging industrial settings.
FAQs of Union Fitting:
Q: How do I install the brass union fitting with threaded BSP connections?
A: Begin by ensuring all pipe ends and the union fitting threads are clean and free of debris. Align the male and female BSP threaded ends, then hand-tighten before using a wrench to secure the connection. The metal-to-metal sealing design ensures a robust, leak-proof joint suitable for water, air, or oil systems.
Q: What advantages does the nickel-plated CW614N brass provide compared to standard brass fittings?
A: The CW614N brass offers excellent machinability and strength, while the nickel plating enhances corrosion resistance and provides a smooth, durable finish. This combination makes the fitting ideal for extended use in harsh or humid environments.
Q: When should this union fitting be used in plumbing or pneumatic applications?
A: This union fitting should be used when a reliable and easily disassembled connection is needed between two pipes, especially in systems handling water, air, or oil, and operating up to 10 bar pressure and between -20C to +120C.
Q: Where can this fitting be applied apart from domestic plumbing?
A: Beyond residential plumbing, it is suitable for industrial pneumatic setups, machinery installations, hydraulic lines, and any setting that requires a robust, corrosion-resistant, and leak-proof coupling between pipes.
Q: What is the process for ensuring leak-proof performance in this fitting?
A: The fitting is engineered with high-precision threads and employs a metal-to-metal sealing mechanism. During installation, proper tightening ensures a leak-proof joint. Its rigid design and precise tolerance further prevent gaps or misalignment.
Q: How does the smooth finish and nickel coating benefit the user over time?
A: The smooth nickel-plated finish minimizes friction during installation, eases cleaning, and provides lasting resistance to oxidation and tarnish. This prolongs the life of the fitting and reduces maintenance costs.
Q: What are the key benefits of choosing this union fitting over alternatives?
A: Users benefit from superior corrosion resistance, precise construction, reliable leak-proof sealing, easy installation, and compatibility with a wide range of operating media and environments, all backed by adherence to international quality standards.
