Duckbill valves, membrane cylinder and tee fitting for the LU05, the parts that quietly cost you suction.
Price last checked at the retailer and subject to change. The button opens the retailer listing in a new tab.
The wear parts of a wearable pump, packed together. Duckbill valves soften with every wash and every warm cycle, and a soft valve stops sealing, which shows up as a pump that feels weaker with nothing visibly wrong. The membrane cylinder and the tee fitting in the same path are here too, sized for the Lulia LU05.
LU05 only, and parts from other pumps that look identical will not seal.

When suction drops, most people turn the level up. The valve is usually the actual answer. Silicone that has gone slack no longer closes fully between pulses, and no setting compensates for that.
That is the ordinary lifespan under daily use. Heavy pumping and hot washes shorten it, light use stretches it. A clearer signal than any schedule: hold the valve up and look at the slit. If it gapes open at rest, it is done.
Valve, membrane cylinder and tee fitting fail the same quiet way, and chasing them one at a time means three rounds of guessing. Changing the set at once settles the question of whether the parts are the problem.
Made for the Lulia LU05. Parts from other pumps sometimes look identical and sit wrong by a fraction, which is enough to leak.

This page describes equipment. It is not medical advice. If pumping hurts, or output changes suddenly, talk to a lactation consultant or your clinician rather than turning the level up.
