Parker RK119B Relieving Diaphragm Valve Assembly Repair Kit for R119 Series Regulator

• Applicable for 3/4" to 1" R119 series regulator

For years my R119 air "relieving" regulator has been working on/off, or leaking air. I cleaned and lubed it with marginal improvement. Well, this kit fixed it and it is working beautifully now.

There is no lube with the kit for the O rings and inner valve assembly.

Other than that it's great.
