Best use case: This cap is the right choice when your original Perko water fill cap has been lost, cracked, or damaged and you need a direct replacement. Its a small part that makes a big difference a missing or ill-fitting cap can allow water, dirt, or fuel vapours to enter the fill port. Confirm your existing fitting is a compatible Perko water deck fill before ordering.
