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.)

Loved this Trelino and all the spare parts

Amazing service, product and easy to use. Have already recommended it to others.

Spare parts.

I live on the road retired to my travel trailer. I like to keep extra parts for most important items so when I ordered my trelino I ordered these inexpensive items just to be prepared.


Works as it's intended. I do however wish Trelino offered all the products to USA customers as they do to their European market.

Be prepared

Living full time in my Campervan requires me to be ready with all my Trellino products. 2 Membranes can last me more than 2 months. Can’t live without them.
