Self servicing maintenance without the need for a vice or specialised equipment. You can now easily undo the area with the regulator knob that has an M8 Hex / Allen key head and clean out your regulator if you have a contaminant get in there.

These are high-quality parts made for a high-quality regulator.

The main reason you might replace these parts is because:

1. You have gas leaking through your diaphragm. (this is extremely uncommon)
2. The gasket on around the edge of your diaphragm is worn out. (this is also extremely uncommon)
3. You have a pressure creep issue. (this is the most likely need to purchase this assembly)

Troubleshooting:
– Regulator Pressure Creep
Regulator creep is normally caused by contamination getting into the seat and seat cap assembly of your regulator. This is normally a result of gas leakage over the seat and seat cap assembly causing high-pressure gas to leak into the low-pressure gas side of the regulator. As this happens your regulator will “creep” up in pressure until the pressure relief valve activates. Replacing these parts in your regulator will fix this issue and only takes a few minutes to replace.
