alcoengine locking nut- replacement  for alcoengine pot or reflux column.

Brass M47 thread

Purpose

• It locks the column or condenser in place on the boiler lid so it seals tightly and won’t rotate or loosen during operation.

• Works in combination with a silicone or PTFE seal to ensure a vapour-tight fit.

• Provides a solid, corrosion-resistant fastening compared with plastic alternatives.

Construction

• Made from solid brass for strength and heat resistance.

• Has a female thread that matches the male thread on the AlcoEngine column 

• The brass allows for repeated tightening/loosening without stripping threads or deforming under heat.

Where It’s Used

• Fits all AlcoEngine reflux and pot still condensers.

• Typically sits under the lid, securing the condenser from beneath.
