Empire Universal HPA Tank Regulator Fill Nipple Assembly

The Empire Universal HPA Tank Regulator Fill Nipple Assembly (40609) is a replacement fill fitting for compatible Empire compressed-air tank regulators.

The integrated back-check system functions as a one-way valve, allowing compressed air or nitrogen into the tank during filling while preventing air from escaping back through the fill nipple.

The assembly includes the fill nipple and back-check strut with an O-ring seal, making it suitable for replacing a leaking, damaged, contaminated, or worn fill-nipple assembly.
