Sealing Membrane (set of 2)

for replacement of membrane inside the lid with opening (extra lid not included) 

The sealing properties of this silicone membrane keep the urine canister closed from the insideensuring that liquid is unable to escape from the canister into your toilet and that any smells are kept away. Even if there is any splash from bumpy roads or tipping, this membrane stays put and keeps your space clean and smelling fresh. In this video, you can see how well the membrane closure is able to keep liquids in where they belong: 

 

If you are a full-timer using your Trelino® on a regular basis, the membrane should be replaced every 3 months in order to maintain the fit and sealing properties. For weekend warriors or part time users, this piece should be replaced every 6 months.  

Scope of delivery

  • 2 x silicone membrane (ca. 1.57 in.)

Membrane lifespan

We love our Trelino, however the membrane closure on the urine container doesn’t stay closed for more than a couple of weeks. We’re on our second one.

The rubber pee valves are not like the original at the end they have a gap

Please advise if I've received 2 defective valves.

Hello Nancy,Thank you for your feedback and for bringing this to our attention. We’re sorry to hear about your experience. Could you please contact our customer service team at hello@mytrelino.com? To assist you as quickly as possible, we kindly ask that you include photos of the defective membranes in your email. If the item is indeed damaged, we will of course send you a replacement right away.
Please note that the membranes are always slightly open by design to prevent the membrane lips from sticking together. Additionally, this slight opening allows air to escape from the canister, preventing internal blockage when liquid passes through. Without this feature, there would be a risk of overflow. We hope this explanation helps clarify their functionality, and we look forward to resolving this matter for you promptly. Best regards, your Trelino Team.
