I cannot yet attest to the durability as I just received it, although it is made with a heavier plastic. So, it seems to be fairly durable. Screwing off the standard Valterra grey tank cap was nearly impossible to remove by myself... even with those plastic wrenches! Took me 15 minutes to remove the original and replace with this handled version. I can now easily turn it with one hand! Wish I'd known about these sooner!!!
