Valve Plug with Pressure Gauge R1/8"

Complete valve plug with a built-in valve and internal R1/8" thread for a pressure gauge. Occupies one of the positions in the Junior pump's valve block.

Application

The plug closes one of the valve positions in the pump's valve block while also functioning as a valve at that location and providing an R1/8" thread for connecting a pressure gauge that monitors working pressure. This design combines two functions in a single part, unlike simpler pressure gauge plugs without their own valve mechanism.

Symptoms – when to replace

• Drop in working pressure despite a sound pump and sound remaining valves in the block.
• Water leak where the plug seats in the valve block.
• Leak at the connection between the pressure gauge and the R1/8" thread, despite the gauge being properly tightened.
• Uneven pump operation indicating malfunction of the valve mechanism built into the plug.

How to choose the right part

Selection is based on reference number 43067 – this variant differs from the neighboring plug 43066 by having the R1/8" pressure gauge thread, so when ordering, confirm whether a gauge is actually fitted at that position in the valve block.

When replacing, compare with the removed plug regarding the presence of the pressure gauge port – swapping it for the version without a port (43066) will make it impossible to connect a gauge at that position.

How does this plug differ from the 43066 version used in the same Junior series?|This variant (43067) has an additional R1/8" thread for a pressure gauge, while the 43066 is a plug with a built-in valve but no option to connect a gauge at that location.

Does the system need to be drained of water before removing this plug?|Yes, replacement requires depressurizing the high-pressure system – it's best to shut off the water supply and release pressure by opening the gun before starting disassembly.

The pressure gauge connected to this plug shows unstable pressure readings – is that the plug's fault?|Unstable readings are more often caused by the gauge itself or air in the system than by the valve built into the plug – it's worth checking the gauge separately first, before replacing the whole plug.
