    Unused membrane LIfespan

    Sheesh!! I sure have a lot of posts on this forum. Is there any records that I could Break? Anyways I got a good deal on A membrane well rather 2, but I won't need to use the other one for a while. How long can they last on the shelf? I could sell it but don't wanna!. Thanks

    If they are factory sealed, I think they will last for years....not sure, I'll get back to you. If they are opened and allowed to dry out they are shot.
