Frequently Asked Questions (FAQ)
Q: What's the key difference between CB-SP-10M-3 and your stainless models?
A: CB-SP-10M-3 uses carbon steel, optimized for non-corrosive applications. Stainless models like CB-SPM-10F-A are intended for high-corrosion environments like marine or chemical processing.
Q: Can I use CB-SP-10M-3 in saltwater or coastal areas?
A: No. For environments with high salt exposure or aggressive fluids, we recommend 316 stainless models.
Q: Is the carbon steel coupling strong enough for high-pressure hydraulics?
A: Absolutely. It supports up to 5000 PSI depending on size, and is fully ISO 7241-A compliant.
Q: Can I get the CB-SP-10M-3 with different seals?
A: Yes. While NBR is standard, Viton and EPDM are available upon request for improved temperature or chemical resistance.
