Gasket for pressure hose for Jura Nespresso N coffee machines

If water is leaking from your Jura coffee machine underneath the unit or into the drip tray, the cause is often a worn or damaged seal on the pressure hose. This O-ring 63444N is exactly the part that will restore the integrity of the pressure system.

When does this part need replacing? (Fault symptoms)

This O-ring typically fails when you see any of these symptoms:

• Water leaking from underneath the coffee machine or into the drip tray, even though the tank is not overfilled
• Visible dripping or moisture at pressure hose connections inside the coffee machine
• The coffee machine makes hissing or sputtering sounds during coffee preparation due to pressure loss
• Coffee flows unevenly, slowly or not at all, because pressure is escaping through the damaged seal

Compatibility: Which models is this part for?

This universal O-ring is designed for pressure hoses in Jura Nespresso N coffee machines. It can be used for any hose secured with a clamp. Specific Jura models compatible with this seal 63444N are not fully specified in the manufacturer's technical documentation – we recommend verifying visual compatibility before ordering or contacting our expert technical support.

Technical properties

The O-ring is made from food-grade MVQ material (methyl-vinyl-silicone rubber), which is heat-resistant and designed for contact with drinking water and food. MVQ material maintains its sealing properties even at the high temperatures and pressures present in Jura fully automatic coffee machines.
