​The PTHC Series NPT Standard Flow fittings by GROCO are 90-degree pipe-to-hose adapters constructed from C83600 bronze.They feature standard flow design, meaning the hose inner diameter matches the pipe size (e.g., the PTHC-750 model has 3/4" NPT threads and accommodates a 3/4" ID hose).Available in sizes ranging from 1/2" to 5", these fittings are UL Listed 647B.However, they are not compliant with the NSF-61 lead-free standard and should not be used in potable water systems.

• Standard Flow - the hose ID that fits is the same as the pipe size (ie: PTHC-750 has 3/4" NPT threads and accepts 3/4" ID hose)
• C83600 Bronze - not compliant with NSF-61 lead-free standard.  DO NOT use with potable water systems
