Q: What is the maximum operating temperature?
A: The standard collar is rated for continuous use from -20°C to 80°C. For higher temperature requirements, we can provide custom formulations (e.g., glass-filled PP) on request. -
Q: Can the inner diameter be customized?
A: Yes, we offer custom sizes. Please contact us with your specific ID, OD, and pressure requirements, and we will provide a quotation. -
Q: How does the 1000 PSI rating compare to metal collars?
