Rocket Espresso Water Tank Base O-Ring – 31x4mm Silicone

Fix a leaking water tank on your Rocket Espresso machine with this silicone O-ring (0310-40, 31.00 x 4.00mm). This is the thicker 4mm seal for the water tank base connection — recommended when the standard 3.53mm seal is not providing a sufficient seal. Made from food-safe silicone for heat and chemical resistance.

Specifications

  • Part code: 0310-40
  • Dimensions: 31.00 x 4.00mm
  • Material: Silicone
  • Note: Thicker than the standard 3.53mm seal — provides a tighter fit but may make tank insertion/removal slightly firmer

Standard Alternative

If you prefer the standard thickness seal: O-Ring OR 04131 / OR 0139 – 32.93 x 3.53mm Silicone (part 1786210)

Compatibility

  • Rocket Espresso machines with base water tank connection
  • ECM Giotto, ECM Cellini
  • La Pavoni Giotto, La Pavoni Cellini

When to Replace

  • Water leaking from the base of the water tank
  • O-ring is cracked, deformed, or has lost elasticity
  • Tank is not seating correctly in the machine

Frequently Asked Questions

Why is this O-ring thicker than the standard one?
The 4mm seal provides a tighter fit than the standard 3.53mm seal and is the recommended solution when the standard seal is not stopping the leak. Note that the thicker seal makes the tank slightly harder to insert and remove.
Can I install this myself?
Yes — O-ring replacement is a simple DIY task. Remove the water tank, pull off the old O-ring, clean the groove, and fit the new seal. No tools required.
