Description of Change

CPC is discontinuing the HFC39 product line. This discontinuation applies to the amber-colored polysulfone HFCs manufactured with a 316L stainless steel valve spring. These discontinued HFC39 products have direct replacements available in the recently launched HFC Disconnect product line.

 The HFC Disconnect product line is manufactured with an Alloy C-276 valve spring rather than 316L stainless steel. Aside from the different valve spring, the HFC Disconnect product line is identical in geometry and functionality to the HFC39 product line and is manufactured from the same polysulfone and silicone materials. HFC Disconnect products will not change as a result of the HFC39 product line discontinuation.

Affected Products

Please see Appendix A within any of the notifications linked below for a list of part numbers that will be discontinued. Within those same notification letters, please reference Appendix B for direct replacement part numbers. The last date to place an order for any of the discontinued products is 26 November 2025.

Reason for Change

With the addition of the HFC Disconnect product line to CPC’s portfolio, there is a level of redundancy within the HFC39 and HFC Disconnect product lines. The additional value that the HFC Disconnect products bring to the market has led CPC to discontinue the HFC39 version of the products. Additional value includes but is not limited to:

• An Alloy C-276 valve spring for additional chemical resistance
• Products sold as connected sets to reduce manufacturing time and quantity of SKUs
• Protective thumb latch cover on connected sets to prevent accidental disconnection
• Protective thumb latch on connected sets to prevent accidental reconnection
• Laser-marked item and lot number for traceability
