Dixon Holedall internal expansion stem, 50mm (2")

This Dixon Holedall internal expansion stem is carbon steel with a grooved end. The stem sits inside the hose and is held by an internally expanded ferrule, which suits concrete placement, plaster and grout, food, air and pharmaceutical hose and wherever flow capacity matters. There are five sizes, from IXV20 for 32mm (1-1/4") to IXV64 for 100mm (4") hose ID.

Dixon's maximum recommended working pressure for internally expanded IXM, IXV and IXH couplings is 600 PSI for hose from 25mm to 75mm and 500 PSI for 100mm hose, at 21°C ambient. For hose that uses ferrules IXF64-2 to IXF64-5. Holedall stems and ferrules are designed to be used together as a coupling system and not to use other manufacturers' stems or ferrules, for safety reasons. A Holedall internally expanded coupling needs strict adherence to the ferrule OD range for each hose end.

Where this product is used

• Grooved-end hose connections on concrete placement, plaster and grout, food, air and pharmaceutical hose
• Hose assemblies where the bore through the fitting needs to stay large for flow

Key specifications

Choosing the right option

Order the stem by the hose inside diameter and the ferrule by the measured hose outside diameter; use a diameter tape for that measurement. One expansion tool is needed for each hose ID. Testing each hose assembly to 1-1/2 times its working pressure for 15 minutes without leakage or coupling movement.

Dixon also offers a 75mm grooved stem (IXV48) that is not.
