Recently, our ACR Copper Fittings have received UL Certification and got 1000 PSI Working Pressure and a maximum abnormal pressure of 1500 PSI. This applies to our ACR Copper Fittings that are up to and including 7/8″ size.
As an industry leader with our ACR Copper Fittings and plan to keep doing so by consistently outdoing ourselves in quality and service. With zero reported failures since 1999, and the quality of our fittings consistently being one step ahead of the competition; the sky is the limit for NDL.
