ORRO Manufacturing Co., Ltd. supplies non-metallic precision parts for HVAC and refrigeration equipment, where constant temperature cycling, refrigerant exposure and condensation demand materials that stay flexible and leak-free over decades of service.
Typical Parts
- EPDM and silicone gaskets — long-life sealing for air handlers, ducts and refrigerant connections
- POM damper gears and linkages — quiet, low-friction actuation for dampers and valves
- Nylon fan bushings and bearings — self-lubricating support for fan shafts and blower wheels
- PTFE valve seats and seals — chemically resistant sealing for refrigerant and control valves
- Rubber vibration isolators — noise and vibration damping for compressors and fans
Material Advantages
- EPDM: Outstanding resistance to steam, ozone, UV and weather over a wide temperature range
- Silicone: Flexible from -60°C to 230°C, ideal for extreme-temperature sealing
- POM: Low friction and high stiffness for quiet, precise damper and valve mechanisms
- Nylon: Self-lubricating and quiet-running for fan and blower shaft support
