Frequently Asked Questions for Fluid Fittings Bulk Procurement

Q: Are your brass fittings suitable for high-pressure refrigeration systems?
A: Yes. Our HVAC Brass Fittings and Solid Brass Fittings are manufactured from high-strength alloys and undergo rigorous pressure testing, fully complying with the safety requirements of AC Brass Fittings in high-pressure environments.
A: Propress Brass Fittings provide a fast, flame-free connection, saving installation time and suitable for sites sensitive to open flames. Traditional brazing (using Copper To Copper Fittings) offers the highest permanent sealing and strength, suitable for critical Refrigeration Copper Fittings lines.
A: Capillary Copper Fittings are among our most precise components. We strictly control the internal diameter tolerance through specialized drawing and cutting techniques, ensuring the accuracy of refrigerant flow, and they are widely used in refrigerators, air conditioners, and other Refrigeration Copper Fittings systems.
A: Yes. In addition to standard 3/16 Brass Fittings and 3/8 Copper Fittings, we support custom manufacturing of different specifications of Copper Fittings and Brass Fittings based on customer drawings and flow requirements.
