Description

Urine Canister Membrane Replacement for Trelino® Composting Toilets Leak and Odour Control

Stop leaks and smells before they become a problem. These Trelino® membrane closures are designed to maintain a tight seal inside your urine canister, helping keep your setup clean and odour-free.

The silicone membrane creates a tight internal seal inside the canister, stopping liquid from escaping back into the toilet while helping keep smells contained.

Swap them out regularly to keep your toilet performing as it should. A fresh membrane helps prevent splashes from escaping, even on rough roads or uneven ground.

Made from flexible silicone, they are easy to replace and clean. A small but essential part that keeps your composting toilet working reliably over time.

Key Features & Benefits

  • Maintains a secure seal to prevent leaks and splashes
  • Helps reduce odours from the urine canister
  • Made from flexible, durable silicone
  • Easy to replace inside the lid
  • Supports long-term performance of your toilet

Prevent Leaks from Your Composting Toilet While Travelling

The membrane forms a tight seal inside the lid, helping stop liquid from escaping back into the toilet. It stays in place during movement, reducing the risk of spills when travelling.

Reduce Toilet Odours at the Source

A well-fitted membrane helps keep smells contained inside the canister. Replacing worn membranes keeps odour control working as it should over time.

Keep Your Toilet Sealed Properly 

With regular use, the membrane naturally wears over time. Replacing it every 2–3 months for full-time use, or around every 6 months for occasional use, helps maintain a proper seal and prevents leaks or odours.

Replace the Membrane in Seconds

Designed to fit directly into the lid, the membrane can be swapped out in seconds. No tools required, making it easy to keep your system running properly wherever you are.
