These OMS Valve End Plugs for Rotating Crossbar Manifolds convert the modular valves used with OMS 200 Bar (V-200RC) and OMS 300 Bar (V-300RC) Rotating Cross Bar Manifolds to single right and left valves. These blanking plugs also fit San-o-Sub modular manifold valves, plus those by a number of other brands who actually use manifold valves rebranded from San-o-Sub.
The picture shows the plug with its two O-rings ready to be inserted into a valve. (Valve not included.)
The Right Hand blanking port valve plug has right-hand (normal) threads.
The Left Hand blanking port valve plug has left-hand (reverse) threads. It has notches cut into the nut head, so that it can be easily differentiated from the right hand blanking plug.
