O-rings for De'Longhi Fully Automatic Espresso Machines, Repair Parts, Set of 2, 44mm These are O-rings for repairing De'Longhi fully automatic espresso machines. ・This is a set of 2 O-rings. ・The size is 44mm (genuine parts are 45mm). ・The ring thickness is 4mm. ・Made of heat-resistant silicone!! Excellent elasticity and heat resistance. The ring's inner diameter is 44mm, slightly smaller than the genuine 45mm. There is no problem with installation or coffee extraction. With the genuine size, the high water tightness increases the resistance of the moving parts, and the accumulation of debris over long-term use increases the resistance and puts a load on the mechanism. The 44mm size allows the moving parts to move smoothly even with long-term use, preventing breakdowns. Available for immediate purchase. No price reduction. No individual sales.
